Good sound

Works awesome! All around good sound. Deep bass. Running off 800 watt amp bridged now. But mite be a bit much. Sounds great at lower watt input too. Been in boat all summer 2018.

Would recommend, crisp sound quality !

Awesome subwoofer!, I installed 2 of them On my 2007 Yamaha jet boat and the system Is clear and hits well ! The water shakes the subs are so good. It's worth every dollar! Can't beat the reliability and the price.

Very impressed

I must say I was skeptical about this speaker based on the price but once I got it installed I am thoroughly impressed. The sound is great and quality is amazing. I recommend this product.

Srious speakers

speakers were ordered black but arrived white. Web has a problem. It keeps trying to switch you to white when you ask for black ? Speakers are a great value for the cost. Bass response is off the chart. Pay attention to weight. These are some serious speakers.

Qiality Sound and price

Nice Speaker, sound is perfect one of the vest in the market

... 1100 watt amp in my boat and it sounds great and hits pretty hard

I hooked this sub up to an 1100 watt amp in my boat and it sounds great and hits pretty hard. It was a definite need for summer fun on the lake .

Great price

Very nice subwoofer. It hits pretty hard. Nice blue led light in cover. Only think I would suggest is pre drill you a few holes through speaker cover to get rid of some rattling when the bass hits. Overall very pleased with this purchase.

Sounds great

Sounds great, I bought more Rockville audio once I heard the sound quality.

Serious bass and full sound

Awesome sound! The power of the amp and that subwoofer bass are amazing and truly waterproof too. I don’t have to worry when I hose out the boat if the get wet.

The performances

For one ease of shopping and delivery.second well built construction of the speaker. They sound fantastic.
