Liked it so much I bought it again

"I installed this as one of three amps on my boat. I wish I had done all three as the atom 8B due to the number of configurations you can pull. I do not use the bluetooth feature, it just packs a clean and powerful sound in a relatively small unit. I love that the amp displays voltage. I use that feature on the boat occassionally but during install it was really easy for people to help as all they had to do was tell me if the voltage was displaying and I knew the system was working. On the boat, the amp runs two 6 1/2 JBL speakers, two 8"" JBL, and a 12"" sub. The fish are terrified when we start to shake the water. In the car I replaced the factory door speakers and added two 10"" subs. The output is set low and they are still cranking out great sound. I was glad to deal with RCA wires and my own speaker setup instead of the factory dash wires with a bunch of soldering. I did not give it front and rear volume control which would have needed a third set of RCA cables, it was not necessary in my install but if I were doing a larger vehicle I would have loved that feature."

So far so good, it's powerful!

"Bought to replace a wetsound amp. that whoever built this razor, spent way too much money on, that decided to junk out! this small compact amp. has more power than you think! Hooked up a wetsound sound bar, 2 can 10's, 2 subs, plus really not sure what all they have going on to be honest and the sound is A+! The cost is Extremely realistic for the working class like us and I couldn't give this enough thumbs up! Would recommend and purchase again! Oh, had to call to ask a question and guess what,,,, they actually got on the phone and helped! So another A+ on customer service! Shipped quick, easy hook up and did you catch that this is 8 ch. , Blue tooth and RCA impute compatible!! Not to mention the blue lighted digital readout matched our glow perfect!"
