X1 Speaker Upgrade Help

Searched and couldn't find an answer, so please forgive me if this has been answered. Boat is 2+ hrs away in storage, so hoping someone might know.

I have the stock 6.5" Clarion speakers, and want to upgrade to JL speakers. Looks like I can use the 7.7" JL's in the cabin, just need to open up the holes.

What about the front? I don't want to use spacers behind the speakers, and don't care about LED rings. My front does not have separate tweeters, tweeter is co-axial with the woofer. Will the MX650/M650 speakers directly replace the Clarions without being too deep and hitting the hull. I know it's pretty tight up there.

Finally, practically speaking, do I gain much by going with 7.7's vs the 6.5's? Is there that much of a difference to the ear?

I’m happy with 6.5s, but the difference might be more than you think. I’m no math wiz, so I can’t calculate it exactly, but 1.1” is roughly 15% increase in diameter, which probably means 25-30% more total surface area. That would sound better for the mids and lows, for sure.

Mx650 if you want to keep the original mounts, M770 if you want to open them open. M770 will take a lot more power and you will hear the difference. I believe the bow speakers will need a spacer to clear the depth on the M770. Running the mx650 in the bow and the M770 in the cabin would be a good option. Power it with a m600/6 will give you 200 bridged to each M770 and 75 to each mx650.

I think I'd be happy with the 6.5's up front too, especially since I don't want spacers and whatnot to fit 7.7's.

I agree that the MX650/M770 combo would be a good compromise. Luckily, I have plenty of power to drive whatever cabin speakers I choose already (gain is turned WAY down for the Clarion's right now).

Thanks for the input guys!

To wrap this up, I ended up going with MX650's for all four speakers. The decision was mostly based on future replacement. Seems like the 7.7" speakers aren't a common size (from many manufacturers). Didn't want to open up the holes and then not be able to find a replacement speaker in the future, if that becomes an issue.

I'm very happy with the MX650's. They sound great and are plenty loud enough for us. The mid-range sounds much better than I thought it would. Anyone looking for stock replacement, moderately priced speakers, consider these.

My one concern with them are the tweeter wires. Since my speakers install into the storage compartments, they are subject to damage. I'll probably make a small shield for some protection.
