I have a Eclipse top of the line deck and MB Quartz components. An Eclipse 800 watt amp. The deck is all copper chips and **** it is cool. I also have the stock Alpine 8' open air subs in the back decklid what shall I replace them with ? I was thinking two 10"s and get a box built face them in the holes on the back decklid with a 400 watt amp what do you guys think ?
