2002 Boxster Bose Sub amp info

Recommended Posts

I found the wiring to this unit on another area of the forum (See attached). The person I bought this car from had the radio replaced with a standard JVC. Rather than wire it through the existing amp, they ran new wires from the JVC amp to the frunck and then cut the output wires from the amp and wired the JVC radio directly to the dash and door speakers. The subwoofer speakers were not working at all. The sub amp was still wired in and I verified it had power. I verified the output wires from the amp are still connect to the subwoofer speakers and work. I tried feeding an audio source into the sub woofer amp, but nothing came out of the sub speakers.


I put the subwoofer amp on the bench, powered it up, fed it some audio and attached a speaker to the output. Nothing. Thinking I had a bad amp, I bought another one on eBay. Same thing. Darn!


There is a bunch of other wires running between the sub amp and the main amp that are just labelled "Term 38" and "Term 31". Anyone know what these are for? A simple amp should not be this complicated !
