My first option was to add another set of factory cans with JL's but it's proving too difficult to find and buy a used set so.... I'm now considering replacing the single towers with Bullet hp 770's. My question is will the 900/5 drive the 770's sufficiently bridged or will I need to switch wiring and run the cabins from the 900/5 and the tower speakers from the 600/4?
The 900/5 is enough power to drive four inboat speakers very well. Just make sure that this particular amplifier is always run into a symmetrical front and rear impedance load. The sub channel is independent and on its own power supply so there isn't a concern on channel 5.
Four channels of the 900/5 bridged into two tower speakers will be about the same amount of power as two channels of the 600/4. Four channels of the 600/4 bridged into two 7.7" tower speakers is a bit rich....although very dynamic. Initial tuning would be critical as would staying disciplined as the day grows long and your ears become fatiqued.
Get with Odin at Earmark Marine for your purchase. He can then walk you through the best tuning procedure. I don't know of anyone who has his grasp of acoustics.
