First off I want to say thank you to Big Jeff and his whole team. I love the podcasts every week. Anyways, these amps are fantastic. I have 2 of them and they are absolute beasts. I can run them for an hour straight on 2 sundown zv6 18s and they barely get warm to the touch. The sound quality is better than any amp I've owned. I'm not even getting their full power either because I am running headway lithium which doesn't hold 14.4v. They literally almost get as loud as my 2 Brazilian 8k amps. If you got the electrical to run these, you will love them. Hands down the best amps I've ever owned. And they came very well packaged as always from Big Jeff Audio. I ordered during a holiday season and my shipping time was still very fast here in Asheville Nc. Anyways, my point is, these amps are amazing and I think they are discontinued so get them while Big Jeff still has some left. Thanks Big Jeff and his Team. Very happy with all of my purchases from you guys.
