I just had an AvicX-930BT installed to replace my Avic-D3 which was damaged in an accident. My problem is only my door speakers are working. I have a Kicker sub amp feeding an enclosed box with a Kicker Comp CV-12 sub and it 's not working. I had my stereo shop do the install, I'm just wondering if anyone has any ideas.

tons of ideals, but it all come down to either being a bad unit or an install F up.

regardless, its going to take some trouble shooting to figure this out.

does the amp even turn on?

is the sub channel turned on?

is the signal coming out of the AVIC?

are the RCA's plugged in to the right connectors?

is the signal making it through the RCA cables?

is the amp outputting amplified signal?

are the subs blown?
