Aftermarket Stereo Install Help !!!!
 
Hi guys installing a JVC double din head unit and have ran into a bit of trouble i purchased a scosche CR4000 replacement interface which included the canbus adapter i wired all the colours from the adapter to the aftermarket head unit and all matched up. The unit turns on and all functions/video work correctly except for some strange reason i cant get any sound what so ever. Also its a 2010 with the infinity sound system. The adapter i purchased is definitely for a premium sound system or so it says Any help would be appreciated thanks.

P.s I have just read this "In Premium Amplified Systems only two input channels can be used from the aftermarket radio" would this have something to do with my problem does this mean i have to wire all 4 speakers to 2 wires hence why they tell you that you lose the ability to control balance and fader?

i cant seem to find anything about your model of interface.. the cr4000 isnt even on scosche's web page. unless i am missing something.

i personally had to bit the bullet and spend over 100 bucks on the one from Pac-audio

Pac-Audio.com Product Details | iPod Integration for your car and More by Pac-Audio - Connecting you to the future

and yes only two inputs.. might want to start there..

good luck

post what you find or fix.

Sorry probs a dumb question but does that mean all four speakers are wired to only 2 on the adapter. also if i was to bypass the speakers past the adapter would that work without throwing codes but still use the adapter for the power supply.

Also the adapter i bought cost me $80 on ebay so gonna try get the money back and buy the pac audio one. the frustrating part is im getting picture but no sound

Wire the front pairs from the HU (white and grey) to the rear pairs on the harness (purple and green). Fade control on the HU should be pushed all the to the front.

If possible go with the PAC Audio one. I bought my deck through crutchfield and got 50% off the PAC one with my purchase ($75).

Since music is only Stereo, I would just wire the two front leads to the interface module. Music only does left and right, not front to back. No need to wire up rear leads. If you are running a sub amp off pre-outs, you can use the Sub pre-out with no issue. If you have non-fading pre-outs, fading everything to the front channels won't impact sub. If your pre-outs fade, then you need to leave fading to 0 (or equal to front and rear).
