Anyway, one of the ideas was to splice the rear speaker wire into the high input on the amp. Since the rear speakers are getting all the sound, the LPF on the amp should deliver only the bass to the sub, correct? How exactly would I go about doing this (before i get out the wire clippers and soldering iron)?
Also, the car has the premium sound system, so the signal going to the speakers is already amped (not a lot), would this cause huge problems for the sub?
Thanks a lot!
