If you surf the majority of the time; definitely go 2 Icons and 2 Rev10’s.
I sold my 4 REV10’s this Spring and replaced them with 4 Exile SXT9Q Surf speakers. Much happier with the sound quality. As they are not loud speakers, they’re not as loud at wake boarding distance or across the lake, but they sound 100% better while in and behind the boat surfing. Going 2x2 gives you the best of both worlds.
Just my opinion.

I would echo KG's concerns. Going with a mis-match of HLCD's and surf speakers is something that the audio gurus on the forums have addressed before. Similar to going with something like a combo of rev8 and rev10. The bigger, louder speaker drowns out the other. You end up having the biggest HLCD walk all over whatever you're trying to pair it with.
In the case of Jeepers, going from all HLCD's to all Surf speakers is great, as it's maintaining a balance. But the mix and match approach tends not to be recommended from my understanding.2008 Moomba Mobius XLV.

Yes, ohms, or the woofer's impedance plays into it. Thats why I suggested the OP go with the dual 2 ohm over the dual 4 ohm he first listed. This gets him from 3ooW rms @ 2 ohm to 500W rms @ 1 ohm.
Keep in mind though, we are talking about an amp that designed as a 1 ohm stable amp. We not talking about strapping just any amp with any random woofer load. Rockford built the amp to be 1 ohm stable, so why not take the same woofer, just in a different coil configuration, and gain 200W rms.
As long as the amp is driving a safe impedance, then 500W is 500W. Put another way, 500W from a 1 ohm stable amp to a 1 ohm woofer is the same 500W to a 4 ohm woofer from an amp thats rated to deliver 500W @ 4 ohm. Now, thats the simple answer. We can dig deeper and say that a mono amp running at 4 ohm is running at a lesser load then a mono running at 1 ohm. Bust as noted earlier, we already have 25% rms headroom in there at 1 ohm.

I’d recommend he swap 2 of the REV 10’s out for a pair of icons.

1 set of Rev 10s is more than enough for just about every application other than winning the who is loudest contest at a tie up. Revs sound great for wakeboarding or turn them down for surfing and enjoy the bass from the killer sub on the boat. My last boat had 2 XM9s, not a Rev10, but could not imagine 4 of them pounding me in the face while surfing. At any rate, these guys know their stuff, listen to them, have your system tuned and enjoy the jams.

If I didn't say it earlier, this was a very nice catch. Simple change for big improvement.
^^^ That should be the take away ... a benefit of getting free professional forum advice.
We can dig deeper and say that a mono amp running at 4 ohm is running at a lesser load then a mono running at 1 ohm. Bust as noted earlier, we already have 25% rms headroom in there at 1 ohm.
Ohm matching is key and getting him setup up at 1 ohm was a solid save. Gets out of Tier 1 but with a 400w RMS sub I'm not sure it gets to Tier 2, in the above scenarios.Last edited by KG's Supra24; 09-18-2018 at 11:39 PM.

I appreciate the open feedback from each of you. I will be staying with just the 2 rev 10's I currently have and running them on the p1000x2. Changed the 12" to the 2ohm and will stick with the p1000x5 for that and 6.5's. Will see how I like them for the next year and make changes if I think I need more. Really just looking for a good clean sound in boat, floating and surf/wakeboard. No interest in competing. Can use that $ many other places. Dropping the boat off Monday morning for changes and will update when it is done.
