just kidding, but ive got a 2000 Jeep Cherokee w/ Infinity Gold system and Im getting a new Kenwood HU and 2 12" subs with a Hifonics amp to power the subs, and I want to keep the 4 mids and the tweeters and use the factory amp for those. But I dont want to loose everything changing headunits, or do I have to change my HU? Please help.
