That is a very nice system.. but i'm olny looking at some subs.. and need help with wiring it.. mostly if i need a crossover, when keeping the 6x9's

Did you even bother to read the list I posted? That's the exact equipment.

Pick and choose.

Both subs are running on the mono 650 amp, and all the speakers in the car are on the 450. You pull out all your pre-existing ***.

Hey man all you really need is two 10s or a 12. JL audio is my favorite. just get a mono amp, 800 rms or so will do. I'd go with phoenix gold. No need for crossovers, just ajust from the controls on the deck to take bass out of inside speakers. The subs will be all you need.

yes you can run just some 10's in your trunk use the RCA converter kit and then use the wire tapping clips to jump from your rear speaker wires to convert the signal to run in the RCA jacks. run a power wire, remote wire, and ground wire to your amp. then hook up the RCA's on your amp to the RCA's on your converter kit and you will have both rear speakers and subs. if you need any other information just e-mail me directly and i can show you the places to find the stock speakers to RCA converter. and you choose your own speakers and amp. i'll even tell you how to hook everything up.

RCA converters suck so bad. The sound quality is terrible, and occasional a high note will squeeze through, causing damage to the subs.

If you are only looking for a little more bass, go with pioneer, kenwood, or a similar name brand. If you want alot of bass, go with JL Audio, Alpine, or Audiobahn

Get yourself a new head unit with a subout function, wire an amp up to it. Then you can control how much bass you want, and if you want all the bass reverted to the subs. This leaves you the option of putting all vocals and midrange through your speakers, and all the bass to your subs.

and this folks.. is called truth.

Very nice work there by SC Customs.

What do you guys offer for the GT Spyder? I would love some subs but the trunk is so **** small.

I don't sell a "drop in universal" fit solution. But, a single 10% corner sub would work fine - otherwise, you can ditch your rear seat and use that entire area to create something over the top.

I have a website, and I have a contact us now link where you can get specific quotes based on what you provide. Don't ask - "How much for an audio system", because that would be about as brilliant as asking a store "How much for shoes". You have to layout what you want or find something similiar, or even sketch an idea and from there - we can ballpark it.

Obviously, any major work we would need your vehicle.

I have an 04 and I am doing something similiar.

The correct way to do this would be replace the head unit wit ha unit that has a "SUB OUT" or RCA output.

This can get costly for a nice one.

If you want to keep the infinity system then you will need a Line Out Converter or LOC.
This same item is also called a High-Low Converter.

This will allow you to run an RCA line to the trunk where you may put any AMP YOU wish, and choose whatever speaker set up YOU like.

~2 suggestions if I may~

1. Choose a larger wire for the power and ground work if your gonna get a large amp, and dont tap your rear speaker or you risk engins noise in your speakers.

2. If you want Bass a crossover is necessary only if you have full range speakers setup. If you want Bass buy a Bass Box and a Bass Amp and no Crossover necessary.

i like his paint hehe. hella cleeen.

dude i totally agree that RCA converters suck, some people refuse to replace a head unit and recently thats all i have been replying to is i want to run subs without replacing my head unit. i just had a blurry moment between couple posts is all.

Get an aftermarket headunit, if you dont, your wasting your money with wanting more bass.Phoenix Gold kicks ****. I have one 10" PG Xenon 800 watts and it is indestructable Ive also got the PG amp, no crossover necessary!Also high pass filter on the headunit is nice to keep highs off the sub and bass off your tweeters and deep bass off your 6x9's. food 4 thought.

Um a good amp will have a HPF on it. And Phoenix Gold kicks @$$? I don't think so, Audiobahn is the way you wanna go for amps, or the best even though they're ridiculously expensive, but they are the best, is Rockford.

Old PG... Rocks Cocks

New PG... Sucks hairy man balls

i wouldnt mind getting a new head unit.. but my gts has a 6cd in the dash, and i dont have alot to spend.!. and im probably gunna take the $$ set aside for the woofers and get an xbox 360..

Yes but if you get a new headunit then you either have to get new speakers or you have to continue to use the factory stock Infinity amp under your seat with your stock speakers otherwise the headunit will blow the factory speakers. But it's up to you.

I prefer PG over almost everything in the clarity/quality sound range Also amp has HPF and subsonic filter etc etc Competion Speakers are a different category and most people dont actually by that stuff for there car, especially if it is a fast car.

also HPF on your headunit mallows the bass to your sub only. you wouldnt have to blow your surround speakers unless your listening to distorted music(by way of turning it up to loud).You could get pioneer yellow ? 6x9's those can handle anything your stk radio can put out.350 w?
