Which JL amp for these speakers
 
I'm looking at a pair of JL M6-770X-S-GmTi's. Their Continuous Power Handling rating is 100 Watts. Their peak is 200 Watts. The JL amp M200/2 is 2 channels at 75 Watts, which seems kind of low for these speakers. The next choice is the M400/4 and bridge the channels which then produces 200 Watts and I think will overpower and blow the speakers.

Thoughts?

Get the m400 and tune it down.

Do you have any other speakers, subwoofers or amps on the boat? How big is the boat? What is your source unit? Need more details

No other speakers, subs or amps. 18' flats boat. Undecided on the head unit. Possibly the JL MM80-HR.

The M400/4 will bring those speakers alive. I suggest the Fusion products for your head unit

Thanks Brian. How do I tune that amp down so I don't blow them. Also, limited dash/helm space. What Fusion head unit do you recommend?

Zero the gains.

You can also look at the wetsounds syn-dx2 for 200 watts in a 2 channel frame or the htx2 for 150 x 2. Their mc1 headunit is excellent as well.

Tune your amp basics. Your protecting your speakers from being blown out as well as setting the max volume without distortion.

Iíve never understood why the JL amps put out 75W RMS but most of their speakers handle 150+. So really calls for you to bridge the channels to get the most out of them.

Iím running JL speakers and a Wetsounds amp. The Wetsounds amps push more power per speaker.

Daimyo68 11-10-2019 07:43 PM

As mentioned, get the speakers you posted about and the M400/4, then tune it down using the instructions in the video I posted. Rest assured, you won't/don't need to push those speakers to their max RMS. You will be shocked at how little gain will be needed to get awesome sounds levels as well as quality sound.

Just because a speaker is rated at a max RMS of XXX, it doesn't need to be run at that level. Running it at its lower "Continuous Power Handling (RMS)" will give you all you want with added longevity.

I have a Fusion system on my boat, 6 speaker system with a 10" sub and Fusion amp, and none of my level/gain adjustments are more than 30%
