Your existing sub is driving 2 x 10" woofer, 2 x 6x9 speaker, 2 x 6" speaker and 2 x tweeter?
My proposal (w/out detailing the existing equipments):
1. Let the existing amp drive the existing 2 x 10" woofer (in the trunk I believe)
2. throw away 2 x 6x9" speaker
3. get a new 4 channel amp and driver the front 2 x 6" speaker and 2 x tweeter via the existing passive crossover
4. Find your favourite SQL CD and tune your system to the fullest.
The objective of my proposal:
1. Try to minimise cost at the same time try to get the best out of it. (to be frank with you, there is no end to this if you keep on seeking the best)
p/s: I'm assuming you are listening to audio music only, not watching a movie dvd
good luck
