I need to buy an adapter so I can get some ports for my subwoofer amp. Where can I get this and what exactly is it called? My local car audio place has it but they are charging $20+tax. I've purchased adapters before for other vehicles and they were at best $7. Thanks.
I tapped the rear speakers for my little Kenwood flat sub. Just regular speaker wire and I spliced the into the cables at the JVC amp.
I've been getting patch cords off Amazon for low cost. Couple times the description was not accurate but can't complain for a few bucks. Also Radio Shack. I am not sure what you are looking for.
I installed a Kenwood KSC-SW10 flat sub in my car. It has the optoin for RCA input or speaker taps. For simplicity safe I used speaker taps. http://www.amazon.com/dp/product/B00134X0AO?tag=priuschatcom-20
