Great Amp
[This review was collected as part of a promotion.] The amp quality is sturdy, and has an overall nice look to it. Came with stickers and directions for installation. I'd definitely say this is for a simple set up, not for completion or any extremely high wattage subs. Sound quality is great with no cracking. Overall my expectations were exceeded and hopefully this amp will continue to work.
Power pack with style
[This review was collected as part of a promotion.] First off, the quality and feel of this unit is solid. Heavy duty, durable, and the perfect addition to your sound system. All connections on the AMP feel sturdy and of good quality. With the unit installed, the interference of electricity was not noticeable. The quality of the unit shows as during full running capacity, the unit stays much cooler than expected. It's a great addition for anyone looking to upgrade their car audio.
Impressive amp
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. This is a well built car amp. It packs an impressive punch. There are a couple of ways you can utilize this amplifier and the instructions are pretty clear.
