Anyone know how the stock basstube is hooked up the the stereo ? Im sure i can handle the rest of the wiring harness for my new head unit, but ny new HU has RCA outputs for the bass that would normally hook into an amp. I dont even know if toyota installs an amp for the tube or if the tube contains an amp. I also dont know which wires in the back of the radio go to the tube in the back. There are quite a few

thanks for the help,

Just picked up my xB 2006 . I have a MTX 404 Amp I plan on transferring from my old Car. I have the new Head unit so looking for any advice with dealing with installing an Amp to it. Dealer told me there is NO rca jacks that plug directly into the unit.

any help is appreciated
