I would like to install a sub in my Lexus IS 300. Do not neccesarily want to remove the factory headunit. The factory unit/amp/speakers do not sound bad. Could I tie speaker-level inputs from a Bazooka or other amp into the rear deck speakers. Unsure because they are amplified already and also I do not want to affect the impedance to the factory amp. Any suggestions?

I would use a high power line output converter (LOC) like the Soundgate pieces and install it to the factory sub wiring and keep the factory sub out so when you cranked up the aftermarket sub the factory sub wouldn't bottom out and ruin the sound.
