Awesome amplifier. Paired it with a Fosgate marine stereo on the boat. Be careful holding your subwoofer. 1st one i bought was too weak. Be sure to get 4 ohm with high rms subwoofers.

Purchased all of my boat audio equipment from Rockville. I was pleased with the ease of installation and the quality look of the product. The sound is fantastic, crisp clear audio. My 2000w amp can easily power my subwoofer and 4 speakers. 10 of 10 would recommend.

First let me start by saying this thing is Spectacular. It meets every expectation of what I was looking for. I give it 10 out of 5 Stars. I can't say enough about how great this Amplifier is. I read all the reviews I could because I had upgraded speakers in cars before, but never installed an Amplifier. My main concern was making sure that I purchased a amp that was not going to overheat and go in to protect mode. Not once has this amp done that due to heat, NEVER ! It's mounted on the back of my Toyota Camrys back fold down seats and it gets hot in there in the sun and still has never overheated. I'm pushing 4 Pioneer TS-A6990F 5 way 700W max and 120W max continuous RMS 6×9's with it. 2 in the front doors and the other 2 in the back dash and 2 Pioneer TS-B350PRO 250W max and 100W max continuous RMS, 3-1/2" High Efficiency Bullet Tweeters in the dash with a Cerwin Vega 7- Band EQ770 Equalizer in the dash with a Podofo Android 7" touch screen double din without a CD-drive. Just Bluetooth and WiFi and any Android apps you want to install on it w/50w×4 of which have its 50w of power set to or turned off in the settings. So that being said, I have each speaker on it's own channel. Also I have no subs as of yet. Really don't need them. The Pioneer TS-A6990F 5- way 6×9's have phenomenal Bass and that's what I searched for before I purchased them. They handle alot of bass and sound good doing it. Right now I have the 2 tweeters up front set on HPF filter on the 2 channels they play off of and set to 4K so with the 2 super Tweeters that each 6×9 also have and the awesome woofers they have for Bass this sounds incredible. I have the volume on the deck at 100% and the amp levels at only 50% even though the speakers can handle much more without distortion and I control the volume with the volume knob on the Equalizer, because the deck is touch screen so I didn't want to take any chances at accidentally turning the volume up too high with an accidental touch. The knob on the EQ is safer. So going by the Amp specs I'm pushing 95watts to each speaker without the chance of ever going higher than the each speakers RMS. With this being said, THIS ROCKVILLE dBM65 MARINE AMPLIFIER ROCKS !!!!!!! It has never went in to protect mode except once and that was not for over heating. It was because I had used speaker wire end plugs that said their outside caseing was non conductive and they were touching and causing a short, because GUESS what the Manufacturer of those speaker plugs LIED ! So once I corrected that problem no more problems. I did install a 5" inch USB fan and a USB power port in the trunk to power the fan to blow air on the Amplifier just in case, but with and without the fan it has never overheated. ROCKVILLE, Thank you so much for making a great Amplifier. You will get my money in the future if and when I ever want more power.
