Stinger Audio MT-600.4M 1000 Watt RMS 4-Channel Compact Marine Audio Amplifier, Class D, Hexfet Mosfet, Water-Resistant, Crossover High-Pass/Low-Pass Filters

These are great for upgrades sound quality great and value for money yes function positive easy install. Quality never better

The media could not be loaded. Probably the best little 4 channel on the market under 150.00!Has amazing sound quality and comes with a bass remote

Absolute junk. Had in my boat. SEALED COMPARTMENT With no moisture or humidity. After a week, began to crackle even though it was installed by a professional, began two rust and chip paint after two weeks. RCA ports are cheap as well. DO NOT BUY. They’ll send you through the wringer just to return it too!

For the money these can't be beat. I have 5 on my Ranger and love them. The get banged around, Muddy and wet and keep on going. Remember to buy a inline fuse!

Love this amp.

Lot of power small size very good sound quality

Solid amp. Easy setup. Hopefully it's actually water resistant. Hardware is solid and that's my favorite part. Construction is great. And compact. Honestly I would not trust another brand for marine other than obviously jl audio but for the price and all it's outstanding. Also it's super easy to tune. I mean seriously some amp are pretty bad to tune this is easy!.

This Stinger amp blew me away! It packs a punch with its power and features, delivering unbelievable value for the price. Shipping was lightning-fast, and the brand name speaks for itself. A+ all the way! My second Stinger amp, and it's even more impressive than the last. The build quality is top-notch, and it delivers crystal-clear highs without any distortion, even at high volumes. This amp is a game-changer!
