'03 RSX sub wiring

there should be a factory amplifier for bose-equipped rsx's under the passenger seat. usually the easiest thing to do would be to use outputs coming out of this amp as high level inputs to your mtx amp. if your mtx amp is lacking a high level input option, then add in a high/low level converter. irregardless, the outputs coming from the factory amp is the easiest way to go about it. you can even find a remote turn-on wire there. good luck!

the bose sub has its own amp which is attached to  the sub unit itself (it is located inside the spare tire well and puts out 100 watts) and this is the line outputs I am using.The voltage seems to be so low that i have to almost turn my gain all the way up on the mtx amp which makes the noise level quite loud,but this seems to be the only way to hook it up. thnx!t-win
