This AMP is well designed for easy, straight foward installation. Comes with RCA and standard wiring connection points. Output uses lock bolt wire anchoring system to eliminate possible shorts/disconnections. Installation and tuning instructions are well written and easy to understand. FOLLOW the tuning instructions regarding the "Gain" feature. It doesn't need to be turned to the MAX setting and your speakers probably aren't rated for this amount of power. This AMP produces sufficient power to amplify four speakers and a subwoofer at a level of dB sufficient to rattle the windows in your car/truck/boat.Ignore the naysayers. This product is well packaged, arrived undamaged, and worked perfectly because I FOLLOWED THE INSTALLATION INTRUCTIONS. Take 5 minutes, read the instructions and you will be satisfied with this product's performance and sound amplyfing capabilities.I am completely satisfied with this product and would repurchase.

The amp is powering a 12" alpine sub tube and (2) 6x9 pioneers, I highly recommend this, the captains mic is great for talking to the crew and other boats, does not get that hot

I have 2 of these. They really boost the speakers. They will shut off when subs get hot but will come back on. I like that feature

I have to say it seems well built. This is one of those you get what you pay for.It kind of gets your attention when you see "1600w" as we all know its at peak and only for a second.Unfortunately this is not one of those amps but its pretty decent for 89 bucks so you can't really complain.I have it pushing 4 Kickers and its just ok for me nothing spectacular but it gets the job done considering its for marine use and you really don't have a huge amount of options.The mic is pretty fun, you can scare your friends as you make a complete idiot of yourself!You can bridge your speakers and or have 2 channels left and right and one sub with the built in crossover which is pretty nice.You will need your own wiring for power. I suggest a good 4-6 gauge wire.It only comes with the high input connecting wires (plug to input of original speaker wires) use when no RCA is availableIf you have multiple amps you can pull off your current RCA's run through this amp and then back out as it has 4 inputs and then 2 to return back out again.If you have any questions feel free to ask I can help walk you through it.

Purchased this to use w/ a pair of 300W tower speakers for my boat. More than enough power. Great sound. Fairly easy to install; simple directions. Impressive so far....can't wait to test on further on the lake and use the microphone feature as well. Great Value and solid performance.

Product worked for a week. Literally. Now you have to bang on it to get it to power on for 5-20 seconds before it turns itself right back off. I do not recommend this amp. Just spend the money on a good one. Lesson learned

I want to thank Rockville support team who helped me tremendously set this new system up on my 25’ Parker. They were very patient with this novice installer. I just finished the installation and am thrilled with each component.I look forward to rocking & fishing for years to come.Capt. Tracy Froitzheim

Althought the price is great it only sounds great for a limited time. I only have 4 6.5 inch speakers and 1 10inch bazooka sub bridged. I wouldn't think it would overheat at all from the seller videos but just playing at moderate levels it overheats and shuts off. It's mounted in a spacious compartment with ventilation and still overheats after about an hour of use. Have to turn the head unit off for a little while and restart way too often. Should have spent more for an alpine or Rockford unit.

I'm not sure why I had to pay an $11 restocking fee for something that was Dead on Arrival. I wouldn't buy from this vendor ever again.
