Speaker Help!!

Hey Everyone. This is my first time asking for help on this forum. I have a DEH80-PRS head-unit installed and put in Rockford Fosgate power series speakers in the front doors and rear deck. I want to power them with an amp (T-400-4). I have no idea how to hook it up to my system. Please help. Also, is it possible to hook it up to the stock unit? I have no preference but just really want to install this. I wasn't sure how to make the wiring connections. I know how to run the rca cables just not sure on the speaker wire. Thanks.

Here is the amp:

I am no expert in electronics but have messed around enough to get myself into trouble with audio, so please provide dumbed-down instructions for me. This would be greatly appreciated.

welcome

first you need an amp install kit. you amp isn't very powerful so you can get away with a 8 gauge kit. though i'd recommend a 4 gauge kit, just in case you ever wanted to run bigger amp, you don't have to spend the extra money on the 2nd kit.

8 gauge
http://www.woofersetc.com/p-6427-spk...-600-watt.aspx

4 gauge
http://www.woofersetc.com/p-10205-sk...ation-kit.aspx

in that kit will be everything you need.

step 1 is to disconnect the battery (very important)

step 2 is to run the red 4 gauge wire from that battery to a fuse under the hood, then from the fuse back to the trunk. there is a grommet just over the brake pedal you can run the wire through. run it to the amp

step 3. use the black wire for ground using a metal screw to some unpainted area in the trunk. then run it to the amp

step 4. run the remote wire (usually its a small gauge, and light blue) from the back of the head unit, to the amp

step 5. run the rca cables (look like any other rca's you would find on a tv, or dvd player) from the HU to the amp along the PASSENGERS side of the car. not the drivers because that's where your power wire comes from the hood and it can cause signal noise.

step 6. run the speaker wires from the amp to the speakers, left and right, pos and neg.

step 7. put the battery back on, and see if it works. it will power right up if you did everything correct. then just tune it and rock out.

Thanks a lot for the post...I haven't bought an amp yet...any suggestions? Also, my biggest concern is running wire to the front door speakers...is it hard to run the wiring to them. I know how to run all of the wiring through the panels to the battery (had a sub) but not into the doors. I will most likely be getting 4 gauge kit. I was going to go with the T-400-4 because I have power series speakers but will take any suggestions for these speakers:

6x9:

4x6:

Any suggestions for amps? Thanks again for all of your help. I really appreciate it.

door speakers are pretty easy, but its also VERY VERY easy to break off the reflector on the door panel to get to the screw behind it.

here is a how to guide, post 4, 5, and 6

I don't know if your running a sub or not, but if you are not the bass is going to come from the rear 6x9s. you don't want a speaker that does not deliver the bass. I made this mistake with a pair of alpine type r's years ago. the bass was just flat because the speaker couldn't go down that low. the 6x9 you listed goes down to 50 which is okay, but not that great.

i'm a man of options so here are a few I would recommend. all sound great, and will give you the full range of sound

http://www.woofersetc.com/p-6692-692...-speakers.aspx

http://www.woofersetc.com/p-6391-ts-...-speakers.aspx

http://www.onlinecarstereo.com/CarAu...KFC-X6900.aspx

also don't be fooled by "4" or "5" way speakers. there really no better then a 3 way speaker, they just add a little tweeter, and jack up the price.

as far as 4x6's go bass doesn't really matter, you want really good mids and highs, and good sensitivity rating (how loud it is) to keep up with your 6x9s. I like the plate speakers but to each there own.

some options

http://www.onlinecarstereo.com/CarAu..._KFC-X460.aspx

http://www.onlinecarstereo.com/CarAu...er_TSP462.aspx

honestly the best advice I can give you is to listen to everything you can and see for yourself what you do or don't like. I can sit here all day and list every speaker I like, but that doesn't matter, what you buy isn't going into my car, its going into yours. with that being said don't sell yourself short just going into chain places (best buy, walmart, abc warehouse) venture out to private shops that sell other brands then the big chain stores. its (usually) a lot better stuff, and its usually about the same price.

Good advise metallman. The speakers will be the biggest piece to effect your sound. My best advise is to be comparisons. Since there aren't many shops around anymore, but you aren't going super high budget, check out best buy to get a good listen. Bring your favorite CDs with you, and don't be afraid to crank it up. Make sure you verify that the deck that is powering them is flat ( bass, mid and treble are at 0), and compare them against each other. Get an idea of how different tweeters sound ( silk dome, metal dome, plastic done...) and how different mid cones sound. Also see if you try to A/B with and without an amp. Most 4x6 and 6x9s are made to run off deck power and might not really benefit from an external amp. You should notice an I crease in mid-bass and increase in clarity of highs, but if you don't hear the benefit then don't spend the money.

If you do get an amp for the speakers, you can either connect up to the factory speaker wire that is already run ( found either at the back of your deck or at the factory amp in the trunk), or you can run all new wires. You won't see much benefit in upgrading from 20 gauge factory wire to 16 as the speakers you have/want are not real high powered. If you do run new speaker wire, make sure at when you run it into the doors that you use the factory rubber grommet that is used for the factory door wiring. It will keep it stealth, clean, and protected.

I would suggest maybe a 5 channel amp to run your speakers and a sub. Even if you add the sub later, it will save you on cost and trouble if you just get a decent 5 channel amp now.
