Great Amp For My Boat!

Jesse from Dunkirk, MD on 6/10/2025

Verified customer (What's this?)
Verified employee review (What's this?)

I paired this with 2 Kicker 45KM84L and 2 Kicker 45LM654L speakers in my boat. All I can says is wow! Amazing clarity and power. The crossover switch is cool because I can send bass to the larger speakers and highs to the smaller speakers.

Pros:

Cons: Only con I have is that the power terminals are a little small and will not take a #8 cable. You need to install a "sta-kon" terminal which is actually a cleaner install.

Terrific amp

William from Beverly, WV on 8/18/2024

Verified customer (What's this?)
Verified employee review (What's this?)

Great amp !!! Heavy duty and marine rated which is perfect for my Jeep JK. Only suggestion I can make for anyone interested is get the 8 gauge amp hook up. I got the 4 gauge and it was a workout trying to get it thru the passenger side firewall. 4 gauge was too big for the firewall and the positive and negative hook up on the amp and I had to improvise. Regardless, this amp has made a world of difference in sound quality in my Jeep. I before I had to have my head unit almost maxed out on sound and still could barely hear anything , and that's with the top on!!!! I paired it with a passenger side mount plate to keep it that much more out of any moisture.

Pros: Heavy duty Marine rated Big but concealable Greatly improved sound quality

Cons: Small install ports for positive and negative hookup

Joseph from York, SC on 7/17/2023

Verified employee review (What's this?)

Inserting 8 AWG wires into the 12V +/GND terminals is a little difficult (don't know why they used these flattened types of terminals on this specific model - their other models includes the regular, larger sized terminals). But, once connected - sounds amazing. Powering 4 Kicker 45KM654Ls. Huge improvement over the boat's "upgraded" Kicker speaker system that came from the dealer.

Great little amp for marine speakers

Charles from Marietta, GA on 6/21/2023

Verified customer (What's this?)
Verified employee review (What's this?)

Great amp, clean audio, and decent price. Installed this to power 4 Kicker 6.5" marine speakers. I was powering them with the head unit at 40W/channel, but this thing delivers the speaker max of 65W RMS/channel and it sounds MUCH better!

Pros: Good power, clean audio Nice durable design

Cons:
