2 12's or 1 15?

[Jphipps187]

Right now i have 2 12" Kicker cvrs and im debating on selling them to get 1 15" kicker L7. What do you guys think about that idea. Is 1 15 better than 2 12's? I listen to my music laud and i like heavy bass, should i go for the 15 or what?

[Metallman56]

imo i'm pretty sure the L7 would be louder. there a very loud sub, they just dont sound all that great.

[Jake]

1 15 > 2 12's

[llsht14]

1 15inch sub has a greater surface area then 2 12" subs. I would go with the L7.

[cardude007617]

i would go with a 15, just not a L7. check out Lanzar 15s (jake seems happy with his) or other competition brands.

[llsht14]

If your going with a round sub get a diamond audio sub. You can beat the hell outta them and they hold up great. Not to mention they sound awsome. You will pay for them tho.

[cardude007617]

heh^ gotta pay to play lol. personally i would never go with a "name brand" outfit for subs and amps. Kicker, RF, sony (well duh there) etc etc. you can do better, for the same or sometimes even less money and you will get a product that will hold up better and sound better than the mainstream brands. anyone seriously into car audio that knows anything will agree to that too.

[llsht14]

well i have my diamond audio subs and i think they are kick ass and no one is gonna change my mind. haha

[cardude007617]

whats ur thinking about 2 15s?

[llsht14]

he should get two 15" subs if he wants to pound the **** outta him self haha. It would be pretty loud. Or you could go with a kicker 18" sub

[ryanbgb22]

6 8in subs ftw!

[Grreen99GT]

whats ur thinking about 2 15s?

whats your thinking about being prematurely deaf???

[llsht14]

^lol lol lol lol lol

[Jake]

Hes being serious lol. I had 4 12's in my old grand am and I honestly did notice my hearing decreasing so I sold em and have 1 15 now.

[Tonyyank]

15 all the way, no L7 though...I had a Orion 15 and I absolutly LOVED it!!! HAd to get rid of it, was going deaf!!

[jperryss]

1 15inch sub has a greater surface area then 2 12" subs.

No it doesn't.

[Ajaxus]

15= ~176 sqin
2 12's= ~226 sqin

So the 15 has less..but it's still a significantly large area.


I personally started with two twelves, I miss my trunk space. I'm going to a nice shallow mount 15, I expect to get back TONS of trunk space and still blow the 12s out of the water.

Trunk space is nice. :D

Are you fu&*in retarded.. gotta play to pay... coming from someone that doesnt want to pay. Then you come off with that lame post there. You need to read, watch and learn before you open your mouth.

You stay in your cheap world.

Here is a qtip, use it to dry the wetness behind the ears ....

[cardude007617]

dude, your 37, you have a CAREER (i hope). im stuck detailing cars at 8 dollars an hour (not bad money actually for a 17 year old) but you can afford to drop 2-300 dollars on speakers. i think i have a pretty nice system for a 17 year old to be driving around with. you must have no respect and are just one of those ignorant people that believe what ever they think is correct and their stuff is the greatest. I'm open to other people' s thinking and brands. Hense why I got my ass out of best buy and into different brands that would own anything best buy could dream of selling.

[Tonyyank]

BTW Sony is teh ghey.....

I had a entire system under $700 and blew $2000 system away in high school!!!

[Mendoza]

I would stick with a single L7 in a slot port box. If your trying to save trunk space i would go sealed but i am pretty sure even sealed requires a big box.

[Rosado]

No my point is that, you are telling people that you would never use a name brand. WHY not? Wouldnt you want to better what ever you have. I guess not.
Respect, I have alot of respect for people on this board. Ignorant LOl far from it my freind. If your asking for an opion I will give it. Either u can afford it or not, its still an opion. Just rember those cheap RCA that was giving you noise. Hence the work cheap. Can you score, u bet u can but it has to be right, not just ordinary. As far as bestbuys goes, thats mainstream, commerical,, but i will say this, every once in a while they have something really good ( or at least the one around me does). When was the last time you seen best buy carry a stroker sub?

[notsoaveragej0e]

lol, I read the first post and was like... wait... how does that make sense?

[cardude007617]

iv not been into car audio for very long, so i really didnt pay close close attention to what Best buy had in stock. but id guess never on the CV stroker. and to comment on those rcas, i emailed the guy before i bought em and he said they were as good if not better than most mainstream brands. i believed him and had to go and grab some stingers a week later (working great btw). its too bad they dont carry the "better" brands like RE, CV, the better maxxonics stuff, Fi, Lanzar, CDT, MA, and some american brands like Zapco and MMATS would never hurt either..... touche?

, I read the first post and was like... wait... how does that make sense?

haha ya....even going the simple way of adding the diameters up 12+12=1 24in so to speak, that still more than 1 15..... unless im missing something to figure in here

[Tonyyank]

Something to do with apple pi :D

[ryanbgb22]

u claim to be all into car audio...but apparently you have never done any real research...or taken a junior high math class for that matter. A=pi*r^2

[jperryss]

I had a entire system under $700 and blew $2000 system away in high school!!!

Isn't it funny how that works? I'm in about $950 (headunit, 5-ch amp, tweeters, mids, and a pair of 15" subs) plus another $200 for sound deadening, wires, etc. and I'm extremely happy with the results. It's amazing what kind of deals you can get if you have patience, are willing to experiment with gear a little bit, and willing to make things fit where they normally wouldn't fit.

Oh yes, I would get these kids that would love my set up and I would trade subs and amps like frickin baseball cards!! But I would try it out in my car and see if it was worth the trade. In some cases I'd be like gimme $50 buck and I'll trade, they would do it, they would put wrong amps to it and blow it...Lots of people out there "think" they know about car audio. You dont know until you've had like 3 systems and blow something :D lol

what kinda 5ch amp u got to push 2 15s with? i dont recall seeing any pictures or lists of your system ever

[Jphipps187]

im not going to change brands, i want to stick with kicker, so what Sub (singular) would you recomend me get to replace to 12" CVRs? L7 solobaric? SoloX (if it will even fit in my trunk)?, or something else?

[llsht14]

15= ~176 sqin
2 12's= ~226 sqin

I meant a square 15" sub but its 225 so its close haha

sorry about my adding.

Anyways is anyone gonna back me up here saying that diamond audio will blow away any of those off brands like lanzar and crap?

I bet my setup of:

Alpine Iva-d300 Indash Multimedia Station
Rockford Fosgate t5002 Amp
Diamond Audio 12" D6 Subwoofers in a transmission line box
Boston acoustics highs

will blow away any off brand system in sound quality anyday of the week. And spl unless its a van with a wall of ****ty subs or somthing

[jperryss]

what kinda 5ch amp u got to push 2 15s with? i dont recall seeing any pictures or lists of your system ever

The amp is a Precision Power DCX800.5, got it BNIB off eBay last year: 50x4 + 200x1. Because of the way my subs are installed, I was able to get away with using way less power than the 15s can take. RMS rating on the subs is 750w each, but they're only getting 200w apiece (wired for 2-ohms, amp is putting out ~400w total) and they still get very close to maximum excursion with the small amount of power I'm sending to them. And as a bonus, I still get to keep most of my trunk space.

My tweets and mids were all raw drivers purchased from PartsExpress (http://www.partsexpress.com). Sound deadening and Ensolite (noise blocking foam) were purchased from Rick at Raamaudio (http://raamaudio.com/cgi-bin/index.cgi).

In case anyone wants to know where my $950 went:
Headunit: Pioneer Premier DEH-P880PRS ($290 on eBay)
Amp: PPI DCX800.5 ($250 on eBay)
Tweets: Dayton Reference RS28 large format aluminum dome tweeters (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=275-130) $90/pair
Mids: Dayton Reference RS180 7" woofers (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-374) $66/pair
Subs: Image Dynamics 'OEM' overstockers $250/pair

And here's how I installed my subs:
http://www.grandamgt.com/forum/showthread.php?t=68606

They're in now, trunk still looks like crap because I haven't had the time to recarpet it, but it sounds great. I'll post more pics once everything's FINALLY finished, it looks too crappy to advertise right now, LOL.

[cardude007617]

ohhh ****ttt your the guy with the infinite baffel set up! i remember seeing that while back and goin holy crud.....nice. im wondering tho, how do u have your mids and tweets mounted......
i asked about the 5ch cuz i know they dont put out loads of power, and was curious how u could run 2 15s off of one ever.

very interesting tho, got any pics of it done

You should be sponsored by like god.................:asshat

wow are we off topic.........sorry.... so to the OP, how extreme in SPL do u want to go?

[jperryss]

Diamond makes decent stuff. I've never run any of their product myself, but I've heard some of their component speakers and they were pretty nice.

I bet my setup of:

Alpine Iva-d300 Indash Multimedia Station
Rockford Fosgate t5002 Amp
Diamond Audio 12" D6 Subwoofers in a transmission line box
Boston acoustics highs

LOLZ

You have subs and you have 'highs'. No mids? And if you have mids, they're mounted in those swiss-cheese stock door panels?

Also, you only have one 2-channel amp. Are you running everything else off of 22w from the headunit?

I bet your system sounds like every other person's who says "my system will blow anything away" but doesn't know nearly as much as they think they do. Overpowering bass, shrill highs, and terrible midbass/midrange.

Does that define your interpretation of 'sound quality'? If so then congratulations, you've got me beat.

[bigstribs]

i have a 12in solo x if u really wanna go kicker.... need to get rid of because i am moving pm me if your interested. shiping weight is around 65lbs. let me know what ya think

[llsht14]

well smart ass. For you information i think i know what im talking about. I install it for a living. I have that rockford powering my diamonds. And a alpine v12 4 channel powering my boston acoustics 6x9 speakers in the back and 1200 dollar component system in the front.

[jperryss]

My mids are mounted in the stock door locations. I surface-mounted them so as to avoid any rear (or front) clearance issues. The door panel is sandwiched between the speaker in front and a 1/2" thick MDF baffle in back, with a few layers of deadener on the backside. Not the BEST way to do it, but it works and is very solid, considering. The backside of the door panel also has quite a bit of deadener on it to minimize vibrations. Even with the subs switched off, the punch (for lack of a better word) from those mids is impressive, enough to make my mirrors shake a little.

The tweets are down in the kickpanels, flush-mounted (for now) and firing directly across the car at each other. Hard-dome tweeters are easier to tame when they're not pointed directly at you, which I learned from my old Kappa tweets that I had in my sail panels last year.

I'm not running any rear deck speakers.

I have no decent pics right now. Someone is making me some MDF rings, one pair to angle the tweeters slightly up and towards the cabin, the other pair so I can make a nice set of grills for the mids. Then I need to re-carpet the trunk. Then you guys'll get pics. :D

But yeah, WAY off topic. LOL

[jperryss]

So? What '1200 dollar component system' do you have up-front? And how's it installed? No sound-deadening (Dynamat, etc.) anywhere in the cabin? The 'best' speaker system means NOTHING if it's not installed to perform the way it's supposed to. You could have $4000 door speakers, but if you just slapped them in place of the stockers, then you've wasted $3900.

And that's kinda the point I've been trying to get across. Expensive equipment means NOTHING, the install is way more important. It's not always worth spending $400+ on speakers, when your current $50 speakers may have plenty of untapped potential.

And sorry, the fact that you install for a living doesn't impress me. 95% of installers don't get paid for doing an excellent job, they get paid for doing a mediocre job and getting it done fast. I've had enough shoddy work done by 'reputable' installers to just do everything myself, unless it's beyond my abilities. Like fiberglassing, which I suck at.

NOTE: That wasn't an attack on you or anyone's installing abilities, which I know nothing about. I'm just trying to find out if you're 'all mouth' or not. You sound like a typical "MINEZ THE BEST LOL!!!111!1" punk, but I'm hoping you can prove me wrong. Got some more details, or pics even?

[bigstribs]

so anyone interested in that solo x :D

cough cough BEST BUY!!!!! sorry, my freind had a system installed at BB and like this kid's ground has to be like 4 feet long.....and me and my freind cant figure out where it goes for the life of us... (there are seat bolts just like any other car...) i was going to have my stuff installed there but i looked at it and thought screw this, i can do better work and im 17 doing my first system ever

[notsoaveragej0e]

EDIT: never mind, Nate said he was talking about a square sub.

[chevy355blazer]

Ok i went from a single eclipe aluminum 12 to a 15 eclipse titanimummummum i didnt think it was loud enough. but i listened to a freind who has two jl w7 with 1000 watt amp. with a really good box. its 10 times louder than 2 12s i got my amp a 1/4 of the way turned up his is 1/2 and hes pissed cuz mines louder. just watchur box size ur gonna lose ur trunk tho. lol:leg
