I am upgrading the speakers on my 2014 Scarab 215. The head unit is a Kenwooid KMR-D375BT.

I am going with 4X JL M3-650X-S and 2X JL M3-770ETXv3 tower speakers.

Question is, what amp should I get for this system. I'm not looking to be heard 4 lakes over but want to ensure the speakers get the power they require.

Thanks.

Totally depends on your budget! If money is no object, I'd go with JL.

I'm good going with JL and would appreciate any suggestions for specific amp models.

Thanks

Something like the M600/6 and run them all at a solid 75w each?

I would suggest a m800/8, run the 6.5 in parallel and then bridge the towers. Would be plenty of power for all the speakers.

I will say this tho, if you have the means,I’ve already been through this and I’m not a JL fanboy….but the M6 versus the M3’s truly is night and day! The 1 inch silk dome tweeters scream! I originally went with the M3’s and decided to try the 6’s and was shocked.

Bridging the 800/8 would push 200w to the towers which are only rated 75w. JL are conservative but their amps are under-rated too and that's a lot of RMS power for M3 speakers.

The M6 towers would be much better suited to the 800/8 bridged, and loud, but OP said he didn't need it too loud.

Sorry but you’re wrong. The rms is 70w for those towers with a peak of 225w. Pushing 200w into those would be dam near perfect

I was wrong on the RMS, I was thinking of the amp at 75w. However no 70w speaker can handle 225w that I've seen. And from JL's website:

"For best results, we recommend powering these systems with an amplifier in the 25-140 W per channel range"

I wouldn't pump 200w continuous into them - they're much smaller than the M6 speakers.

Well to each his own. Been doing audio upgrades for a few decades now and have always been a rule of thumb that it’s better to over power speakers then it is to under power them and this isn’t even overpowering them. 75w v 200w is a huge difference and I’m certain the JL’s can take that continuous power and sound phenomenal all at the same time even with it being the M3 line.
