    Big power for a small chassis

    The amp is an absolute monster. Purchased as an upgrade for the JP33 I was running. This thing is tearing up 2 DC XL15's at 1 ohm like it's nothing. Will be upgrading to 2 IA Judges wired to .5. Some of the best amps I have ran and I have been through alot. Highly recommended.

    Little monster

    Posted by Chris on Jun 27, 2023

    I've been running a crescendo amp at half ohm for a long time, I gotta be honest and give crescendo that credit if your looking at one get it but if your looking at these JP line amp get it instead.. the crescendo at 15.3 volts all I could get was 5700+\- watts... after watching the dyno from the jp63 there was no way I could pass it up for under 1000 bucks

    Even better than I expected this thing is a straight monster. I am beyond impressed with it. I highly recommend it to anyone. My best money ever spent on car audio period. JP you knocked it out of the park with this line of amps.
