HELP!!! I bought new tower speakers and an amp...now what?

I have a 2005 Moomba Möbius LSV. My son just got a summer internship working for Harman just in time to qualify for their bi-annual sale at some ridiculous prices. Harman has access to quite a few companies that sell sound hardware. One of which is JBL. So, I decided to purchase a pair of tower speakers and an amp for my Moomba. Let me say that I have very little stereo knowledge and now feel that I might have bit off more than I can chew.

They’re all by JBL products as follows:

Speakers - 8” 150Wrms, 450W peak, 4 ohms
Amp - 5 channel, 1800W peak

I’m hoping it’s enough for a decent system.


Now the problem. I didn’t realize what I was getting myself into. LOL. After receiving the goods I started looking into how to install them and came up with a bunch of questions. Some of which are:
1) Can I connect this amp to my existing speakers and my new tower speakers? If not, how would the sound be if I only used the tower speakers? Or do I need a 2nd amp for my existing speakers?
2) I need to purchase a new stereo unit that has blue tooth capability...and recommendations? I have a lot of CD’s also and wouldn’t mind being able to play them also. (I know, I know...old school here. LOL.)
3) Can I do all this on one battery, or should I really have two? And it so, this will create a whole new list of questions like how to wire, switch/link, location, etc.
4) What wire gauge for the speakers? I bought some 16 gauge, but after multiple searches it looks like I might need something heavier like 12 gauge?
5) How and wear to mount the amp(s)?

Anything you all can do to help guide me to completion will be greatly appreciated. And warm weather is due here in Michigan soon!

Thanx!

Where are you in MI? I might be able to help.

I live in Novi, but my Moomba is up North by Hale.

I’m in Commerce Twp. So super close.

Any advice would be appreciated.

Do you know what model amp it is?
Sounds like it might have 4 channels and a sub channel which would be good for in boats and a sub. But it might work for towers.

It’s a JBL Marine amp MA4505 w/ 5 channels.

Looks like you could run it bridges at 4Ωx2 and get 130W per channel. Should work.

It’s really meant for the in boats and a sub but you could use it for the towers. Personally I’d use it for the in boats, add a sub and buy another amp to run the towers. Then you would have a fully kick ass sound system.

I’m not what “bridges at 4 x 2” means. I would prefer not to dump more money into it if I can. I would think these speakers and amp would be a HUGE improvement over what I have now...would you agree?

You could make it work. You just need someone who knows how to wire it up.

If you get the boat back to Novi, let me know.
