Re: New tunes...and Bazooka tube question.
Great to hear! You know.. I can't kill my M309 for the life of me. It's now 4 years old.. has been left out in the rain with the faceplate on and the stereo cover off.. gets beat up 3-4 times a week.. and no matter what, it still keeps on ticking. I'm waiting for it to die so that I can get the newest version with a front USB connection..!
Where are you planning on on mounting the Bazookas? My reservation with the self amplified Bazooka tubes is that while the tubes themselves are weatherproof, the amp is not.. and you'll most likely have the tubes somewhere where they're exposed and therefore the amp itself will be as well. Don't expect too long of a life if this is the case.
Personally, amplifiers are so cheap these days that I would rather pay $100 or less for a basic sub amp and be able to hide it somewhere. For under $70, you can get yourself a decent amp that will power a couple of Bazooka tubes just fine.
For an off brand non-marine amp but decent quality, people seem to have good luck with SSL. (

If you want the durability and weather resistance of a marine amp, then go MB Quart all the way:

Keep in mind that you don't need a ton of power for those tubes as they make a good amount of sound if you load them right by firing them into the underside of your dash or the like. Bass likes to resonate off of and inside things, remember. That MB Quart amp will power them great if you bridge channels 1+2 to one tube and channels 3+4 to the other. Or.. go with the higher power SSL and just run it in parallel to both.
I've posted this pic a few times, but here are a couple of 12" tubes under each dash firing into the side of the hull. It doesn't get better placement than this:
Where are you mounting things? Is the boat garage kept? Are you wanting BOOM or just fill? It's best to lay out objectives and what you have to work with and then design and choose equipment from there.
