I drive a 93 Acura Legend LS Coupe. Since my rear speakers are blown. I was thinking on replacing all 4 speakers in my car, and so my next question is If I do get new aftermarket speakers, will I need another amp to power that up? If so is a low wattage amp good and how many channels? This is really my first time trying to get these sound system to setup up and I don't want anything to go wrong. If any information is needed please do ask!
