What's up guys!

I'm a newbie to the forum, and I got myself into some real trouble! I was installing a system in my Audi A4, which has the Bose system, and I ran the the RCA input form the back 2 speakers to the amp. Now, the system was working for a while, but then all of a sudden, ALL speakers stopped working except for the front drivers side speaker, which is only playing REALLY low. I wanted to know if I blew the Bose amp, which is located in the trunk. Or if I maybe blew the channels in the radio? Any input would be GREATLY appreciated!

Thanks, Ryan

Did you use a power converter from the speakers or did you just tap in to the speaker out puts and splice it directly in to the leads if so you just killed the amp.

Thanks a lot! Looks like I have to go buy one! Any suggestions on how to run the input to the amp without blowing anything?

Did you replace the head unit?

On your radio wiring harness, there should be a blue wire that powers on the bose amp. Check to see if there is 12V running through. If not, check the fuses. you have to make sure the wire that runs to the rear bose amp is seeing the 12V, either by using the 12V signal from the radio or tapping from the fuse block

to run input to the amp, you either need a new head unit with pre-amp outputs or use a Hi to Lo convertor, then run off the rear speakers.

i don't think the new amp will work if you tried wiring the speakers' output straight to the new amp's input without the Hi to lo converter. if it did, it must have been really distorted at the default gain level...

You can tap in to the speakers but you need to fit a power converter for the RCA's then it will be fine.

I did use a hi to lo converter. That's why I'm so puzzled as to why I would end up blowing the system. All I know right now is that only the drivers side front door speaker is working. But it's playing REALLY low. Hopefully soon, I'll get sometime to check the whole thing out! Are you guys SURE that it's the amp that is blown?
