Money well spent

Recently purchased this amp and I'm very impressed with the quality in both the design and sound quality. I feel I would be getting a good deal if this amp was twice the price.

Sounds fantastic

I paired this with a Skar SDR 12 wired down to one ohm and it shakes my car like no other. Not to mention it had amazing build quality, and I love the fact it came with a bass knob so I didn’t have to spend an extra 30-50$ for one. Overall, if you need an amp to power a 12 or 15 I would go with this.
