i had a pioneer avec z1 installed in my g35 coupe 6mt. everything worked. i recently installed an amp kit and ran all the wires. now i'm not hearing any sounds from any speakers. the amp turns on also. what rca outlet do i connect from behind the head unit? is it the subwoofer out? could that be the problem? the head unit also turns on just no sound. thanks for the help.

 

Your effort into a question really affects the amount we can help you here.

Is the amp power a sub?
Is the amp powering speakers?
Is the amp a 2 channel? 4 channel? 6 channel?
Did you have bose before?
Do you still have have any factory components install, if so which?
Did you do it all yourself?
What wires did you run? "All" doesn't help here.
Where did you ground it?
What model of amp is it?
Did you install a sub?

 

jus a fyi u do kno the head unit has rca out to the amp but u gotta redirect the speaker wires from the amp back to the speaker wire harness in back of the head unit. u did that right? lol

 

yes the amp is power to a sub, 2 channel amp, yes i have bose before, front and rear speakers factory, the pioneer avic z1 came with car and it looks like it was done at shop by looking at the wires, i ran the power wire from the battery to the amp, the remote from behind the head unit to the amp, and theres 4 pairs of rcas behind the head unit i used the subwoofer out/something i can't remember, i grounded it where the spare tire goes. the amp turns on but why do i have no sound coming from the speakers?

 

what do you mean redirect the speaker wires from the amp back to the head unit? what speaker wires are you referring to?

 

So you do have sound coming from the subwoofer?

First guess from this would be that you didn't connect the amp turn-on wire for the Bose amp when you spliced your amp into it.

Here's how it should be wired:
Z1's front and rear RCAs go to the Bose amp through stock wiring (Metra 70-7551 harness or equivalent was probably installed by whomever did the Z1).
Z1's subwoofer RCAs run through new RCA wires to the subwoofer amp.
Make sure the amp turn-on wire is connected behind the headunit so that both amps are turning on.

 

sorry i meant "jus a fyi u do kno the head unit has rca out to the amp but u gotta redirect the speaker wires from the amp back to the speaker wire harness in back of the head unit"

 

the sub didn't actually make noise. since i have an aftermarket head unit and aftermarket amp for the subwoofer do i need to do anything to the stock amp or stock amp harness?

 

Is your amp power light coming on?

I assume you have this amp hooked up to a new sub?

Did you mess with the existing connection from the Z1 to the Bose amp, such as the RCA connections? BTW, on the Z1 I believe there is only 3 sets of RCA outs, not 4. Are you sure you hooked the sub RCAs up to the amp and not the Video outs?

 

You shouldn't have to. Actually, let me rephrase that. I didn't have to. As long as it was all working before, unless you disconnected something it should still work.

 

the rca harness does have 3. the one i plugged in was subwoofer out/non fading. could i have possibly i have switched rcas that's why no sound is coming out?

 

the only thing i did was splice the remote wire of the radio harness and ran it to my amp and connect the rca subwoofer out to the amp also. then i had no sound at all. i disconnected the remote wire and hooked it back up to the regular harness and unplugged the rcas and the sound came back on.

 

The remote wire needs to be connected to both the new amp and the regular harness.

 

so this is the picture of how the remote wire is connected just from the head unit to the harness. I need to splice it and keep them both connected and then run another wire from this harness to the amp? like a three way? also when i had everything hooked up remote to the amp and rcas subwoofer out to the amp, my amp turned on. the issue was just there was no sound.

 

also the rcas i'm suppose to connect is the subwoofer out/non fading to the amp right?
