Okay I have two JL audio W3 12''. They RMS at 300 and Peak at like 600 or 700 and are 4ohms. What kind of amp would be the best, should I bridge them or not or what, an dI don't have much money, around 300-400 to spend. I can get a 725 watt rockfordfosgate amp for $250. So should I do that or what? Thanks guys.

You can get a JBL 1200 watt amp for about 270. I have the 600 watt amp and love it.

Are they D2, D4, or D6? That will be a factor in which amp to get, so let us know. It'll say on the back of the sub. Let us know so we can give better advice....

What model # is that Punch amp? Not recomending anything until I know some specifics! ;)

The foolproof choice of course is the JL Audio 500/1, it's the perfect match for a pair of 12W3's, doesn't care which impedance they are, and is just an all around kickass amplifier. You can find them around $350 to $400 online, retail is $599.

What kinda box are they in, or are youplanning on getting one? This will make a bigger difference than the amp!!! If getting a cheaper amp means you can get a better box, that's the way to go!!

I am doing a custom sealed box and they are D4. I am not sure the spec on the rockford amp, so I dunno. Thankyou for all your help though.

If they're D4, get a good 500 to 800 watt 2 channel amp, or the JL 500/1 (it's the only monoblock that makes full power into 4 ohms). You could also get a monoblock amp like the JBL ones everybody likes that's stable into 1 ohm, but I wouldn't recomend it. That Punch amp will probably do the job if you want, but get back to me with the model # so we'll know for sure, otherwise any QUALITY 2 channel amp in the 500 to 800 watt range.

If you're getting the box custom made anyway, go ported, you'll thank yourself later. ;)

I am going with the JL 500/1. At Car toys around here, I can get a referbished on with a warrenty for like $269. So I am thinking that, b/c I am hidding the amp anyway, thanks for you help, I'll put pics up when I get done with it all.

Where are you hiding it at?

Car Toys is an excellent company, they'll take good care of you. I used to work for them up in Seattle. Tell your salesperson that you know a guy who worked at the home store who's employee number was 597. He'll sh*t himself on the spot. :lol:

Anyway, for that Price, don't even comsider anything else - the 500/1 rocks. Do get a ported box, though! :thumbs:

Thankyou for all your help, I am thinking about putting the amp under the cover for the spare and take the spare tire out, or Building another part onto the box itself. thnakyou for all your help and let me know if you have any suggestions

You can always put it where I put it, just make sure to buy an extra fan to keep it cool. Check the pics out at my car domain site.

Okay i fI am getting the 500/1 JL audio amp. The guy said when hooking it up, that each sub would be getting 500 watts, but I would think that they would only get 250 each. So can you clear up all this. B/c I don't want just 250 to each sub, but I want 500 to each.

Thanks

JL rates both their woofers and their amps very conservatively, but very accurately compared to other brands.

Regardless of the actual power involved, trust me when I say the 500/1 will push two 12w3's right to their considerable limits. ;)

dude I have the exact setup you are considering.... 2 JL 12W3's running off of a JL 500/1 amp. It is impressive and I don't think you would be disappointed! As for saying that the speakers could handle more, they definitely can, I have two friends running the same amp on 1 (one) 12w3 and neither have blown a speaker. So you could even run the JL1000/1 if you wanted. Just my .02

Tell me if this is true, one of my friends told me that you can blow your speakers easier if you underpower them than overpower them. Obviously you can blow them if you put alot more power than you can handle, but he said most people blow speakers because they are underpowered. Is that true?

I have definitely heard the same thing about underpowering speakers being a bigger cause of speakers blowing up. it was explained to me before why it works like that, but my memory is shot. I guess when you overpower a speaker it doesn't necessarily make the sub louder but makes it respond much quicker, making it hit a lot faster.

Underpowering can blow a speker because the listener is more likely to run it to full clipping and thus blow it with a distorted signal, wheras overpowering will allow you too keep things tuned down and clean, and you'll only risk thermal failure - which is only a problem if you jam on it too long at full power.

As for the 500/1 W3 combo - I dunno, man.... I've blown pairs of 12w3's with a 500/1, and I've nearly finished off a pair W6v2's with the 1000/1. I wouldn't hesitate to put the 1000 to 3 12w3's, but 2...? I dunno....

so does the 500/1 JL audio amp run 500 watts to each sub or 250? B/c if that is the case I might get the JL audio 300/2 or a rockford 350/2 amp. Let me know what you think?

Thanks,
Jon

AmIGrand

It'll run about 300 to 350 each. Don't worry about it, it POUNDS. I've done that combo in many, many systems, and have yet to be disappointed. ;)

I am probably going to get the 500/1 jl. Okay, the guy at car toys said that it would run 500 watts to each sub since I am havignt wo subs. B/c something like it drops down to 2 ohms and double the power, is that right?

well from what I have have heard and read in the **** that came with my amp, that dude is telling you wrong. what makes the jl amps so awesome is the fact that you can show the amp anywere from I think a .5 or maybe a 1 ohm load up to like a 4 or 5 ohm load and it still puts out it's rated power (500 watts). the amps maybe be underated and actually put out more than what they say. Either way there is no worry of blowing the speakers with that amp, supposedly that amp is designed to be the perfect match for two 12W3's.

I would expect someone at Car Toys to know their sh*t a little better. Like uratool said, the JL amps output is mostly unaffected by impedance. They put out rated power into any load between 1.5 and 4 ohms.

Dude, quit stressin' it - it's the right amp for those woofers!!!
