I am a distributor for all three. MBQuart just came out with an excellent set of coax speakers that I highly recommend. Their marine sub is not yet available. They are even coming out with a marine head unit real soon.
I have set up numerous systems with Babbs. To use the 10 properly, you have to set it up as a full range speaker and give them a dedicated true 50 to 75 watts each. Picture them like an EV concert speaker. They are loud and move sound well. For clarity, I usually add a set or two of MBQuarts.
Rockford Fosgate amps work very well in boats. I have brand new RF amps on sale for $125 each and about 40 available. I offer white fiberglass gelcoated sub boxes for $180. Call 813-882-8477 with anything you need or email [email protected]
