Garmin Fusion AM Series Marine Amplifier, 500-watt 4 Channel, A Garmin Brand

Replaced the original Fusion amp on our 2012 Regal boat with this. First one was factory installed and lasted 10 years. This is really the original amp with a new cover on it. That was great because I could set it up just like the original. Been on the boat three months now and sounds great for our purposes.

Good product

I have a fusion radio and now that I install the Amp it sounds amazing

This is a great amp. I replaced my older Clarion APA4203 with this and even though I used the same speakers, the sound is sooooo much better. Very easy to install and Fusion has great tech service if you need help

2 years in very easy marine conditions and the device is dead. From the beginning, I have had nothing but problems with a full Fusion Marine speaker, sub and amp system. I have had the system installed for about 2 years, but honestly the amount of hours used is pretty low because the first year, was a lot of trouble shooting the systems.My system includes this AM504 as well as their 2-channel amp. Recently this amp has gone into fault and I have tried everything to get it out of fault and working again. Customer Service is always very helpful, however Fusion's 1 year warranty is pathetic. This amp looks like the day I took it out of the box except now it's going in the trash. The amp went into fault randomly, then after pulling it all apart and putting it back together came back online...then a day later went back into fault. I followed the steps provided by Fusion to test the unit...but nothing came back other than stuff can happen to these units. My 2-channel amp unit works fine, but honestly I am just waiting until that it too has an expiration date. I will be doing more research and will not be buying anymore Fusion products from here out. If a product like this cannot last a minimum of 5 years trouble free, honestly more like 7-10, I have no need for it and will not support the company.This device was store in a cool dry place out of direct sunlight and could not be safer marine conditions. The entire system going in was all brand new including all wires, cables, speakers and power source. This product was either too delicately designed and made, design to expire after it's warranty, or just a fluke failure, regardless, I will no longer be a Fusion customer. I hope this helps other folks out there looking to spend their hard earned money on a good, reliable, quality oriented company. Good luck and do your research.

AMP WORKED WONDERFUL FIRST YEAR, TOOK BOAT OUT OF STORAGE AND 1 SPEAKER NO LONGER WORKED. I LOST THE 4TH CHANNEL NOW IM RUNING WITH MY SPEAKERS BRIDGED. AMP STILL WORKS GREAT OTHER THAN THAT AND THE QUALITY OF SOUND DID NOT CHANGE FROM BRIDGING SPEAKERS.CROSSING MY FINGERS THAT THE REST OF THE CHANNELS HOLD UP.

Fusion MS-RA60 Marine Stereo and this amp don't work like they claim. On the back of the MS-RA60 there are only one channel ( Speaker jack set plug in). So you can't have a rear or front channel. Clearly the MS RA60 can hard wire but the amp will only take input jack left and right ( One Channel) The Amp ( Fusion Entertainment 4-channel Marine Amplifier) and the phone app is smoke and mirrors as well. The Stereo and the amp don't talk to each other its all manual ( Knob tuning by hand) Sound Good and much better than the stereo the boat came with.

Bought this amp in August. Installed it in October, and have used it 4 boat rides. Amp went into protect mode. Checked all my wiring, unplugged everything and did multimeter test on everything, and amp was dead. 2 other buddy’s have had the same problem, theirs lasted a bit longer 6 and 8 months…. Love the head units, but amps don’t hold up well.
