Yep, lineout converters can be bought in just about any car stereo shops, I think walmart and bestbuy has them too. Turn the bass on your factory deck to zero or flat then adjust the gain on your subwoofer amp to get the bass level you want.So I have to run it off my wires designated for my rear speakers (6x9's) and this will split the signal, convert it, and run both rear speakers; including the amp?
