Hello, I am trying to install a subwoofer to my stock Bose system using a high level to line converter. Since both rear speakers are blown I removed them and ran those wires directly to the converter. The amp is powering up but I am receiving no signal to the amp. Has anybody experienced this problem?

 

Your not receieving any signal from your rcas. Make sure ur wires Are hooked up correctly to the speaker wires. Or swapp ur rcas around though im pretty sure its the wiring that is the problem.

 

i double and triple checked everything and still nothing. Im thinking about just pulling the head unit and using those inputs. I assume you need a special tool for that?

 

yea u need special tools to take out the stock radio. maybe since ur speakers are blown u arent gettin any signal to the amp them. Have u tried using the front speakers?

 

Wrongwrongwrong. The front 2 speakers use NO amp. They are direct connection as the tweeters act like resistors in this case.

The REAR have a single INTERNAL amplifier usually mouted right at the bottom of the left speaker (If this is the 96 B5). Thats where you get your signal from. Also if the speakers blew, meaning the AMP caused it, your stereo is probably long fried in teriyaki sauce by now.

 

Its a 01 B5 S4. I can see that one of the speakers are ripped and i think the other one is just rattling a little bit. They both receive signal. I still cannot figure it out. I have tried different patch cords. Maybe the line output converter is no good?

 

I just replaced the converter and that fixed the problem. Sounds good but still needs some fine tuning. Pioneer Premier 12" with a PA BAMF 2000D amp 1200watts RMS @ 1ohm in a 1 cubic foot sealed enclosure.

 

not bad sir take sum pics if u will. Thats alot of power running to just one sub. U shoulda ported the box it woulda sounded sick. Also i would suggest to get a cap to get a little extra power and help ur battery deal with the extra flow of current. if u need any help tuning ur amp hollar at me. glad to see things worked out for you.
