Default Which amp with a pair of JL M880's?

Hello,

My Memphis marine 8's have destroyed cones on a 22' Pursuit CC. I'd like to upgrade these speakers to JL M880's.

Will a JL M400/4 suffice wired 200w RMS @ 4 ohms x2?

I don't think my current amp will work with these upgraded speakers (Memphis 16-SR2.150 50w RMS @ 4 ohms x2).

Thanks,
Jonathan

Your good to go. Let me know if you need help with the speakers.

Is this a correct wiring diagram example of my desired setup?

Where is the best place to purchase JL M880's?

In addition to the proposed setup (2xM880's and M400/4 amp), instead of tossing current amp, can I keep the Memphis amp 16-SR2.150 and add a single subwoofer in mono configuration?

If possible, what would be the best JL subwoofer paired with the Memphis amp? Memphis 2 channel amp bridged for sub would be 150w RMS power x 1 @ 4 ohms. Which would work best - JL M10 250w @ 4 ohm or JL M10 175w @ 4 ohm? Would the M10 under perform with Memphis amp?

I can always remove the Memphis amp if it's not worth the headache adding a sub with M880's.

Thanks again!

You might try Odin with Earmark Marine. Odin has a simple price matching policy and is an authorized JL Audio on-line dealer. So you get a JL Audio factory warranty, full technical support, and someone who really knows the audio category.
I'm not aware of another THT sponsor that is a JL Audio authorized on-line dealer.

Personally I like clean music, and unless you get a good sub setup, the M880s will probably provide plenty of bass. To keep up with those M880 I don't think that amp will do it.

Thanks for the tip! It would be cheaper and less complicated anyway to remove the current amp and run M880's alone.

They should be a HUGE upgrade from current Memphis Marine 8's.....more than double power output. Very disappointing to see the Memphis speaker's cones degrade so rapidly. I hope these JL's are more salt and UV resistant.

Are we sure that a JL M400/4 bridged would not overpower these coaxial JL M880's?

Would a JL Audio MHX280/4 pair better?

Power doesn't kill speakers, distortion does. I used an M400/4 for M770 pair and they worked great. Just don't drive them to the point of distortion and you will be fine.

Wet sounds ht-4 for you setup. It's $10 more and it will make ur speakers bump louder. I had the m400/4 powering m770's and when I upgraded the sound was much louder and clearer.

Wet Sounds HT-4:

RMS Power @ 4 ohm Mono 300 x 2

Seems a bit overkill...

Again we come back to power not killing a speaker but distortion killing them and blowing them.
