I did not make this setup in the car, the original owner of the car did but here it is:

2 Phoenix Gold amps
2 pioneer tweeters, 2 6" door speakers, 2 6" speakers behind the seats
The subwoofer is a 10" infinity

The car is an S2000 btw.

The guy did a real clean job of all of the wiring and even left the wires for the subwoofer out so when I get one. I put the black and red wires to the subwoofer box and I hear the sub getting power, but it does not put out any sound. I have two other cables that look like they plug into the amp. Each amp has an input and output area for two cables. Each amp has the inputs currently plugged in.

Btw, one amp is for the behind the seat speakers, and the other is for the tweeters/door speakers. Hope this is enough information. Like I said, it's getting power but is not making any sound.

I don't know very much about audio and wiring. And the only reason I went out on my own is because the previous owner said all you need is a subwoofer and to run wires to these two and connect them. Had I known it would be more involved than that, I would have taken it somewhere, but now I may as well do this myself, with the help of some HTers

 

Is the head unit he was using still in the car? How do you know the sub is getting power if there is no sound?

 

Yes its the same head unit. I know it's getting power because when I connect the red and black wires I can hear it turn on.

 

you should have a power a ground and an on/off wire from the headunit. then speaker wire from subs to the amp.

 

Hear the speaker turn on? What does that sound like? Have you checked all the settings and connections on the amps?

 

Sounds to me like there is no sub amp and he is connecting the sub amps power and ground to the sub, "I can hear it turn on" [POOOooooop hummmm]94

 

Thats kind of what I'm thinking FCM.

Are you sure you are connecting the sub to an amp not the power and ground wires? Post up some pics. My guess is there is wiring to hook an amp up and you need to put an amp in with the sub. That would explain why you have the other wires there which I'm assuming are RCA's. Are they the type of plugs you'd plug into your tv set for a dvd player?

Post up some pics of the setup and I'm sure someone could help you more.
