    • Amp is amazing definitely recommend!
At first when I was looking for a good amp to use on my dual 10” star subs I wasn’t sure what would be a good amp so I read some other reviews on this amp and I got mixed reviews some say it’s good and some say it’s not. Well I’ll tell you what based off my review this amp is amazing. It is fully adjustable it is easy to setup really nice quality sounds amazing. The bass knob is smooth to turn and it has light indicators on it which is nice, this amp has my car shaking with my dual 10” star subs. I highly recommend this amp! But overall it’s personal preference. ... show more

    • Junk
After 2, yes 2, none will power on. I’ve been doing stereos for over 25yrs. Only reason purchasing, I was looking for a 1ohm stable amp. I currently have a working amp in my truck so I just reinstalled it. DO NOT BUY THIS TRASH! I was just trying to upgrade for my future set-up.
