Review on 🔊 Hifonics TPS-A500.2 THOR Series Class-D 2-Channel 2-Ohm Stable Powersports Amplifier for Polaris RZR/ATV/UTV/Cart/Boat" - Revised: "Hifonics TPS-A500.2 THOR Series Class-D 2-Channel Powersports Amplifier for Polaris RZR/ATV/UTV/Cart/Boat (2-Ohm Stable) by Charles Chambers

I bought one of these it's part of a jet ski project with a pair of Polk Audio Marine 6 1/2 and the amp doesn't work more , 1 channel expired in less than an hour of usage. I checked all the wiring, everything was ok, I found something weird, so I ordered a second one, and this time the same thing happened, the channel disappeared after half an hour, although the gain was only 2/3, and there was no none Distortion. so they didn't overtake. These amps are just cheap Chinese crap. I would suggest using something different and not using an MB quart as it is the exact same amp that just has an MB quart label on it. Maxxsonic bought the MB Quart a few years ago and the quality has sucked. I would just go with something else like a kicker or some other brand that is a true marine amp.
