I plan on ripping out the entire bose unit. IU have a pioneer premiere head but, hey, that may be 50x4 but because of the bypasser u install with the head unit so I byass that amp I only run the measily 15-20 watts a speaker. So those will be goin buhbye with two 6.5JL in the frot and two 4x6s in the back. Then those subs come into play and the 500watt amp is plenty for JL low wattage handling.
Note: I plan to run the 4 speaker thru the amp on the deck.
