2005 Xterra SE problem

So I love my steering wheel controls, paid for them and want to use them. So I have upgraded the front and rear speakers, ran new wire, installed an audio control LC8 (ya I know I only needed the 6 but I didn't know if I would install it before the amp or after) and at JL 500/5 amp in that little place in the back.

So the LC8 allows you to a) install it after the Factory rockford amp and send RCA signals to a new amp or b) remove the rockford amp completely, install this in its place (receiving inputs from the deck) and then send RCA signals to an aftermarket amp.

So my install is rockford deck, LC8, amp and then speakers. I installed everything and I am not getting any signal from the deck. The LC8 line converter is power up, but when I test the 4 sets of signals form the deck there is nothing( the signals are front LR +- and rear LR +-).

There was 2 grounds to the amp. I thought there may been a reason so I hooked them up to the line convertor.

The deck powers up and seems to play CD's and get radio.

Does anyone have any ideas what the deal is? I have installed stereos before and have never come across this.

Cheers

Welcome to the Club!

I too have done stero work in the past. I have not dealt with the Rockford unit in the new Xterra's as that was an option I didn't want. (aftermarket for everything)

Have you tried swapping the LC8 so that it is after the factory amp? Just a bit of speculation here, but since the Rockford unit is technically a non-powered unit (relies upon the amplifier to provide power to the speakers) that the signal is too weak from the back of the deck to the LC8. The multiple grounds might also be an issue.

What do you mean 2 grounds to the amp? explain a little further. What model number Amp are you using? by running new wire, do you mean all the way from the speakers to the amplifier?

It's hard to troubleshoot via the internet, but keep posting, and we'll keep troubleshooting.

Thanks for the welcome to the forums.

So no I have not install the original amp back and then put the LC8 line convertor after the factory amp. I will have to try that to eliminate that.

As for the ground, on the schematic it shows 2 lines coming from the original amp (ie pin 3 and pin 8), they join up and then go to ground. This is the ground that I used for the line convertor.

I have used a multimeter to check the voltage coming from the deck(on all 4 channels) and there is nothing there.

Yes I did run new wire all the way from the speakers to the new amp. I am disconnected from the Xterra system except for the inputs from the deck.

Ah, apologies, I didn't realise you had removed it entirely. I thought you had simply bypassed it. very strange you are getting no signal at all from the multimeter.

Let me know if you swap in the factory amp and then what happens. Wonder if there could have been a short in the radio itself?
