Just a girl with a cool car that had a garbage radio. I had negative bass so I saw the reviews on this and ordered it. For the price it’s great. You can adjust the amount of bass which is really nice if you just wanted an extra kick or to make your head bleed lol. Good quality imo. A little large though barely fit in my trunk had to take my truck liner off shove them in then put liner back on lol. Just took it to Best Buy for install (: it’s been a few mos they’re still sounding great.

It’s great. I love my new sound system and it’s among sone of the best cheapies in the business. To things to be aware of is the size and weight of this. It’s 82lbs in total but it’s of great quality. I love the provided wire kit also, 4 gauge cable is more to an ideal for this size of kit. Secondly, I’m sure you know that 2800W is just marketing. You’ll get at least 1050W RMS, and even then, I wouldn’t push it that far. Either way, I’m glad I got this. Oh, the sub has a strong factory, almost manufactured plywood+glue+fabric smell.

Wow. Just wow. Hookup was pretty simple. And really thumps. When I really want to shine i turn the bass knob up and go with the flow. Then I have to constantly adjust the rearveiw mirror from the rattling the bass causes. Very good value for the money.

Installed with no complications, but after about a month there was a noticeable decrease in the sound quality as well as the loudness of the bass. No settings were changed on the head unit or amplifier after being tuned. Customer service also takes forever to respond. Overall would not recommend purchasing this brand.
