Posted by Chris Lamons on Jun 26, 2025 I have 3 JP43 amps, 1 running 4 sundown X-series v.2 6.5 subs, 2 running sundown U-series v.2 12” subs in custom enclosures that D4S built for me. I had some issues with the JP43’s, but JP and his crew didn’t hesitate to make sure I was taken care of immediately. I can say that I will be purchasing all my car audio from D4S from now on. Great bunch of people 5 Very powerful Posted by Darrell on Jun 02, 2024 I have had a lot of amps in my days but this is the most powerful amp I have ever had. My subs are rated 2400 watts rms, they can only take half volume before bottoming out. Love this amp 5 Fantastic amp Posted by Will B on May 23, 2024 I have this bad boy pushing 2, Deaf Bonce 275's and it is abusive. Giving it proper power (370 amp alt and 2 D4S LTO 6.0) is crucial to it's performance. Love D4S! 1 Trash Posted by Max B on Jan 06, 2024 They won’t post this but I’ve had more problems with this than a hifonics amp or any other amp. They don’t post bad reviews. Waste of money 5 Amp Posted by Josh on Sep 29, 2023 This thing gets down 5 Awesome Posted by Michael Beckham on Aug 26, 2023 Awesome amplifier, played a little 4 hours straight with no problems. 5 Very strong Posted by Kelvin Flowers on Aug 05, 2023 I would recommend this amp very strongly and I'm going to order 2 4 channels soon. 5 JP43 Posted by Derek Foster on Jul 07, 2023 Amp is amazing has tons of power an looks amazing also but only problem I had was that it didn't come with a bass knob which left me unable to use it but I did have one overnighted which wasn't cheap but over all amazing product and I will continue to support JP and buy as many products of his I can. The amp not having a bass knob isn't his fault but I am still waiting for customer service to send me that an the right size wire. 4 JP43 Posted by Derek Foster on Jun 28, 2023 I bought this amp to replace my SIA3500 an so far I'm impressed with it but what I'm not impressed with is with whoever I called at the shop I bought 1/0 wire also with the amp an received 4g an no bass knob with the amp which is a huge inconvenience so they said they would send me out everything but only received one color wire no bass knob so I ended up having to overnight a bass knob while was $179.00. An still don't have the other wire or bass knob. I know they may be busy but just sucks when you make plans for something to not get what you're waiting for. 5 Jp43 Posted by Lester Bonnette on Jun 21, 2023 Just installed a week ago out of every amp I've hooked up to a set of skar audio 18s within the past year this has been the only amp ive actively been able to get the subs to move very happy with my purchase will be building my system up with your products thank you for having a product that is completely up front with accurate wattage and information Next View All Close
