Thanks Ron. I also failed to mention, sort of, that I connected all new JLA RCA cables and have my speakers set up on 3 zones. Really nice to actually be able to control speakers in each zone. The Wet sounds amp that will power the 8's only has low and high pass. Have it set to high. From what I've read want the frequency somewhere around 60 - 70Hz? You're at a point now where adjustments become somewhat subjective. Work with the adjustments until it sounds the best to your ear and you're done.

Ok Captn Ron I have another one for you.... lol
So my other question is this...
If I determine the power from Wet Sounds HTX2 amp (150w x 2 at 4 ohms - no idea what the max wattage is?) isnt driving the M880's sufficiently, would it be acceptable to bridge the amp such that it is pushing 600w x 1 at 2 ohms which I'm guessing would amount to 300w to each speaker?
The speakers are 4ohm.
If so, how would i write this?

You could try it. The two M880's would play back in mono, but on a boat I don't see that as a problem. The two M880's would have to be wired in parallel to show the amp a two ohm load and that would be very easy to do and not involve any more wiring than you have now.

By mono you mean just on a single channel with only one input for control? In other words i wouldn't be able to control each speaker individually for things like fade or balance?

No, the diagram shown shows a series connection, which in this case will double the load the amp sees, 8 ohms instead of 2 ohms.
When the amp is bridges the manual will show you that only two of the speaker taps are used. Take one lead from each speaker and wire it to one of the tabs. Take the remaining two wires and connect them to the remaining tab, this is a parallel connection.
From the perspective of the diagram connect the plus wire of each speaker and attach it to the plus tab on the amp, connect the negative wire from each speaker to the negative tab on the amp ad you're done.

Never mind, the amp is only stable to be bridged at a 4ohm load only.
But it sounds like at least according to the rated RMS of the speakers at 125w continuous power, this amp should be sufficient as wired.
JL does rate the speakers at a much higher peak RMS of 250w and I'm not exactly clear how that correlates to their continuous power handling of 125w?
The 250 peak power is what got me to thinking these speakers might require a bit more juice to push them sufficiently.

I think you'll be good with the amp you have. In practical terms what you would get with a bigger amp is less distortion particularly when you're playing it loudly, but you won't get any more volume. A 250w RMS amp with 500w peak power isn't going to sound twice as loud, it will only sound slightly louder, but the bigger amp will sound a lot cleaner. I can go into a very technical dissertation of this, but I'm sure it would be another dose of mud!

If not, there is always the option of buying another amp, after all it's only money. I did send JLA a note too on my amp and these speakers, hopefully they feel the same way.

I'm anxious to hear your thoughts on the 880s.
I was planning on running 4 770s in the stock locations with a 4 channel amp, but was wondering the same as you about the 880s adding bass.

Have you thought about adding a subwoofer to augment bass? JL has an infinite baffle M-Series subwoofer, which might add punch to your bass if that's what you're looking for.

Yes, but I didn't know where I would mount it (other than through the side of the console) and not really sure I need it anyway...just thought the 880s might be a little improvement. I'll shut up now and wait for Fishnfools report, lol.

Looks like I'm good according to JLA...
Hello, the amplifier you have is plenty of power for the M880 speakers. We list a range depending upon the listener and the goal of the system. Typically for very heavy listening with newer, boosted music we would want to stick closer to the RMS rating to reduce risk of the speakers over heating from too much average power. For moderate listening or for those that listen to a wide variety of music we can go above the RMS rating for more headroom on certain types of music. You are right in the middle which should be great.
Sincerely,
Eric Cole Technical Support Specialist

Nice reply from JLA, I'm sure this will give some degree of comfort now with the audio components that you have. Overall you must be pretty happy with the end result now.

That reply was somewhat of a relief. I have a habit of jumping the gun sometimes and end up with the wrong damn thing. I just hope I haven't set my expectations too high.
