O.K, what boat manufacturer has the best stock stereo. Mine is a new Supra 22 and it's pretty good. It came stock with the following:
Kenwood Head Unit
6 Interior Kicker 6.5" coaxels
4 Tower Kicker 6.5" Components
10" Kicker Sub
Kicker 250.2 Amp running Towers
Kicker 700.5 Amp running Interier and Sub
Overall this system sounds pretty good but sub really rattles due to being mounted on a a baffle board under the dash.
I have added another sub/amp in a box (JL 10W6 with 250/1 amp) plus a pair of JL Tweeters) and the system is more than adequate. I will probably not do anything else or replace any components at this time or at least until I hear something better.
