Sony XM-604M Limited Edition Amplifier

Over 2 years old and still rocks the boat

Have had this amp in our boat on fresh water for just over 2 years. We are out every weekend and a couple days a week too. The amp is covered form most of the weather but had been through many storms and has got wet and has never failed. We use 1 deep cycle battery and can be cranking out the toons all day and in to the night with out having to start the eng.
Sounds great we love it.

Works Great

I put this in my boat to power my tower speakers. Love the sound.

As advertised

Very good small unit, installed on a 21ft bay boat with small console, great setup with Ipod integration and enough power to drive four speakers well. I would recommend this unit.

Solid

this is a solid little amp it sounds clean if your looking for power this is not the amp for you i just use it to run my highs

Reliable, clean and exceptionally powerful

I am running 4 kicker 6.5" speakers down to 2 ohm off the the front channels of the amp and 2 kicker 10" 8ohm down to 4 ohm off the rear channels of the amp and the power and clarity is exceptional.

good for basics

Well it would be good for a basic system in a fishing boat but it does not have enough power for the sony 10's but it does power the 6.5s great and the built in cross overs work well but not for the big speakers even brigded it still is bairly enough for the 10s to work ok. Would buy but its not as much power as it says! I bought 2 amps 2 10" subs and 8 6.5 all sony seem to be great just the amps. Power is over rated but works great for everything else!!

Perfect

Great product, easy installation, great sound, great price.

Does the job

Good amp. I'm not pushing anything too massive but it sounds good. It is bigger than I expected. I did not look at the dimensions before purchasing. I barely had room to put it where I wanted it in the boat. High and Low bypasses are a little annoying just because the are on specific channels rather than being able to choose. I think the low is on the front channel and the high on the rear. It did not seem to match with how I wanted to run the balance through the head unit so I turned them off, but it works as advertised. Not a flashy looking amp you will probably want to hide it somewhere. If you want flashy look or lights look elsewhere. All marine amps should be six channel, but this one does what it advertises.

Provides clean strong boost

After getting my boat with the factory head unit and speakers in it, I opted for sony's marine unit to add capability to the boat for using ipods-sirius-mp3 discs etc. That went great, as I could use many new modern devices, but the sound was terrible with my 2 little 25 watt RMS speakers. So then I dropped in some new polk (100 watt RMS) speakers. Much better sound but now the head unit couldn't push enough power to the speakers and the unit would start to clip the sound at higher volumes as it struggled to try and keep up. So to cure this I opted for this amp. Now I have what I consider great, clean, clear, crisp sound at very loud levels without any distortion. Now I am not the biggest audiophile out there and this is my first install of head units, speakers and amps but it is all very clear and easy to understand and do. I guess now my next move will to be to buy a sub woofer to run off the amp and then to buy a wakeboard tower and install some more speakers and then buy another amp to run those and then buy the remote commander for the stern etc...But seriously this amp so improved the overall sound and capabilities of my system that it is now something you want to use and listen to.

Great Amp for the $$

I paired this amp with 6 infinity speakers and Sony head unit in my 22 ft Bowrider..It does a great job with no issues after several months out on the water...I would recommend them
