    • Powering 4 8” JL Audio Marine Speakers
Size: 500 Watt Class A/B 4-Channel
In a pinch I decided to give this Amp a try. Figured even if it took two per season it was still cheaper than buying my 5th JL Audio Amp. This thing cranks out the power. Sounds great. No issues. Based on how well this Amp had done, ordering the mono amp to power a 12” subwoofer. In the middle of the lake shore can hear us loud and clear. If I had any complaint, it sucks everyone is complaing about how loud we are now :) ... show more

    • So far quite good
Size: 500 Watt Class A/B 4-Channel
I was a bit suspect of the quality given the reasonable cost. I installed this as a replacement on my boat driving 4 3-way 6” full range speakers on two channels and a 10” sub bridged on the other two. The crossover adjustment is very straightforward and I had the system dialed in quickly. Power is smooth with no distortion at high volume and sound quality is strong. Highly recommend. ... show more

    • Powerful Super Purchase
Size: 500 Watt Class A/B 4-Channel
Verified power claims with multimeter and set up gains with oscilloscope. This amp is a great value. I’m only pushing 2 sets of Fusion Signature Series 6.5s but they sound great and the amp didn’t cost $400+.

    • Very happy with the purchase
Size: 500 Watt Class A/B 4-Channel
I am a novice and installed this myself. It took a few hours and am very happy with the results. I am running 4 Skar 6.5’s off of the amp and they are so loud and clear. Love the system. I did find it a bit cumbersome dealing with the connections because it has tiny screws that you need to tight and loosen with an Allen wrench. This was my first install of an amp and I think if I had to do it again it would about half the time to install. So loud!! ... show more

    • Don’t buy this product!!
Size: 500 Watt Class A/B 4-Channel
The amp quit working 1 month after placing in my boat! Went into protection mode when it was not in use and hasn’t turned in since. I would advise against buying this product. On the other hand, their speakers sounds amazing! I have the 6.5” and can hear them from hundreds of feet away! Buy a different amp and you’re set. ... show more

No, I will start off with saying in the beginning, I was very very VERY skeptical about Skar Audio. I heard alot of good/bad stuff about them. I almost bought one of their ZVXv2 subs but it didn't come in a 10 inch, instead I found a brand new Orion hcca 10 on sale with warranty. Goldmime of a sub! I was watching countless videos on YouTube about the brand, with sub, amps, door speakers etc. I finally bit the bullet and bought this one. At first, the main issue I was experiencing was getting power to the amp. My own operator error, hey I am not perfect lol. Once power was established correctly, the blue LED light on the side came on and I was so relieved. I am a firm believer in Skar Audio. Day and night difference with my new (4) Kenwood 5 way 6x9s in my Dodge charger. If you are hestitate about a product, YouTube it and do the research like I did. Instead of me buying a mainstream overrated 4 channel amp (built off overhype from anywhere between 200-525), I got this one for $135 on sale price with Amazon. My opinion, this amp is underrated. I might have to get a big mono Skar Audio amp to feed my Orion hcca 10 sub. Hmmm, decisions........ decisions ... show more
