  • Good quality low price.
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. ... show more

  • Vehicle amp and stereo system
Super great system, my daughter was so in love with it when we got it set up in her truck. Everything was sent to us right there in individual packages telling us how to put it all in and it was so easy. It is very good quality and it sounds awesome. We had to turn it down a little bit because it was literally rattling her truck. It looks and sounds like it'll hold up for a long time. I probably couldn't have got a better deal with all the stuff that came with it and how to put everything together if I had went somewhere else. ... show more

  • Very Good Sound. Buy It.
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. ... show more

  • Mismatched setup for sure
I purchased this package as a display for my shop back in 2021. I used it as an example of what you’d need for a setup and that you could do it pretty cheap. Had a customer come in(16 years old) with his first car and he wanted some thump in the trunk. He had $250 to spend so I made him a deal and we set this up in his car. Let me tell you that tuning this amp is an absolute nightmare. Gain potentiometer is finicky and is really hard to dial in as its increments in value are not even and jump all over the place. But eventually it was set, set pretty low, anything over about 10% was clipped and distorted. You wanna know what the crazy part is? It still sounded distorted through the subs, this was after about 30 minutes of pink noise to break-in the coils. Of course initially the customer was happy once I got everything set. He had some bass and he got it for essentially labor for the install. Then he calls me about a week later and asked if I could retune it. Of course I asked why, and he said he just wanted to be safe because the subs sounded odd and his amp would go into protect mode. After checking everything, it was all set where I left it but the amp had changed its output(probably due to internal heat changing impedance values) and was clipping at 50% volume. We got everything set again. Same call about week later and disaster struck. The voice coil in one speaker popped. Customer never touched the amp or HU settings. This being said, this setup is definitely on the budget side in every way, and that’s not in good ways for the most part. Wouldn’t recommend to anyone. Just save another $200 and buy the Skar setup for $500. It’ll outperform most things at its price point. ... show more
