View Full Version : aftermarket radio help

So I bought this Sony Bluetooth radio on black friday and FINALLY got around to installing it yesterday. Wow is it cool! Only one problem: no sound coming out of my rear speakers. I used a radio harness to make the install easier but after doing some research I guess I need to find a way to send power to the rear amp to make sound come out of my speakers. How do I do this? I guess I need to tap the red 12v wire but idk other wire I'm jumping with this.

Also, what do I do for antenna plug?

you need to wire the rear amp power to a power line from the hewdunit. As for the antenna, you need an adapter thing. I'm on my phone now but ill post up a link when I get home if no one else does by then.

Could you possibly use the power antenna plug to power your amp? This is redundant for the B5.

1. Make sure you spliced and connected enough wires

2. Make sure the RCAs are connected, I believe if you do not have bose, the grey and white ones need to be connected (Someone correct me if i'm wrong)

I also had a hell of a time with the system and head unit. Also, make sure you wire the amp (i'm assuming non-bose) to the rear speaker as it was stock
