hi. i was wondering if DB6501 would work on my subaru impreza 97 stock stereo which is 80watts not sure if 4x80w or 4x20w i couldn't find more info on that. it probably is 4x20w though. so due to the fact that DB6501 power handling is 100w, im guessing per speaker, will my stereo handle it? if not what wattage do i need ? or how does that work.
