Just removed some subs and speakers from my 288, these are drop in ready and like new. I have some MB Quart 12" Subs in perfect shape, They are mounted 1 Sub per enclosure and I have a set. Look and sound awesome. The best part is they fit perfect under the rear seat one on the right and one on the left, which still left room for water tank or bumpers or anything, Excellent set up and sound Awesome. These subs are 2 ohm dual voice coil and they pound! Can send pics if you would like.
Also have some Eclipse 6.5 marine speakers that are like new and sound great. Pm or email [email protected] for more info.. Dont want to cut holes in your boat, these subs are the setup
