I am very pleased with the amp. I have clamped over 3k at 2ohm at 13v. I have this amp pushing 2 resilient sounds entry v2 10s and they are taking the abuse like a champ. Great quality and the clip indicator is great too, it matches exactly with the dd1 meter. I would definitely recommend buying this amp if you are in the market for some great power then this is the amp for you. View All Close
