Rockville Atom 8W 3500W Peak 8-Channel Marine Amplifier 4 Ohm, Bluetooth, Marine-Grade Water-Resistant, Compact, for Boat and Marine Audio Systems

Wow. Just added the amp to existing stock stereo. Pretty much plug and play . No extra sub and wow did it wake up the stock JL m55 head unit. Full range of sound and loud. No need for a sub.

Let me start with I don't write reviews unless I'm wowed and saved me money. I had an issue with my amp, and the customer service team was incredible! They not only provided a full replacement but also took the time to explain how to prevent similar issues in the future. Their proactive approach and willingness to go the extra mile made me feel valued as a customer. Highly recommend Rockville for their outstanding service and commitment to quality!I 1.

The Proactive Approach - Rockville didn’t just fix the problem they helped you avoid it in the future, which builds trust and loyalty.

I installed this on my Pontoon Boat with 8 - 4 ohm speakers. Wow, does it sound good? I learned a lot in the process. My head unit distorts at about 75% volume. So, I replaced my very cheap head unit with an Alpine receiver, which has no distortion at 100% volume. Then I tuned the amp with a DD1, and oh my gosh, what a difference that made. People can hear me on the other side of the lake. The 3500-watt label is a little misleading. On mine, the amp is pushing about 73 RMS watts per channel at 4 ohms or 584 watts total with my 8-speaker setup. I highly recommend this amp, especially at the price.

Works amazing running 4 tower speaker and 4 inside the boat on this amp.

all i can say is this amp is amazing. it has enough power to run the 10" and 12" subs and four 6.5" speakers on my boat. it is amazing. this is a hot deal for what it can do. the only complaint i have is that even when the volume is set to low on your phone the speakers play at 100% max volume when first pairing with phone!!!! you have to quickly try and RESET the volume again to low..........

Best bang for your buck! Half of the channels went out on my old amp, and the wiring was confusing from the factory, so I bought this amp to run the 6 interior speakers and 2 tower speakers, bridged in a series. Plenty of power, and good sound quality coming from all of the speakers. I changed my battery to a group 31, and went with the 8 ohm configuration on the tower speakers so I wasn’t draining the battery on the water. Sounds great and is very loud!

Great amp. Happy with performance. Happy with using single amp for 8 speakers.

Bought this power eight speakers on my pontoon boat. It worked great the first summer, the second summer it quit working about a month after the warranty was over. sat on the phone, trying to get a hold of technical support for over an hour finally gave up and ordered one from a different manufacturer with better support and warranty.
