Amplifier recommnedations
Starting to put together a system for the boat, so far have mtx 7.7's, looking for a decent 5 channel amp to push 4 of the mtx's and a couple 10" subs. any ideas? I do have an old hifonix zues sitting on the shelf but one of the channles has a bit of noise, fixable easily??

JL Audio MHD or HD amps. Marine if in an area that will get wet. Sweet thing about the HD series is they will push their rms rating whether the engine is running and batteries are at 14v or when the boat is off and batteries are down to 12.5 v

I would recommend a amp that is efficient. The JL marine amps are designed to not drain the battery. The output goes down with lower battery voltage. As mentioned above the other amps will keep drawing more and more as the voltage drops. Yes you have more power out of the amps but not for long.
I would also look at digital amps. class D amps will be much more efficient then class A/B designs.

I have a Memphis 1100 class D for my subs, (not marine version) kept in cabin. Batteries last alot longer Been great for around 7-8 years pounding 4 subs at 1 ohm. It did start poping the fuses at the end of this season. Im going to send it back to memphis, heard they have a flat rate to repair. Heard the JL are great too.

In the Donzi I have 12 JL M770 (7.7" components) and 4 JL 10" marine subs. I went with 2 900/5 amps for 8 speakers and the subs and a 600/4 for the remaining 4 speakers. It sounds great and is very loud but I do regret not going with separate amps for the speakers/ subs. While my configuration is better on the batteries (I have 2 group 31 Odyssey marine batteries dedicated to the stereo). Looking back, I should have went with 3 600/4 for the speakers and 2 600/4 for the subs. Really really wish JL would come out with a marine HD 6 or 8 channel amp that pushes 150w rms per channel. Would only make sense as boats typically have quite a few speakers.
