Amp is a MONSTER!
I have this jp43 wired at 1 ohm on 2 Sundown Xv2 12s powered by a 320amp Mechman and 2 XS D3100s. This system is in a 07 Ram 4 door with backseat delete. I haven't metered it yet however, my back doors are flapping like a bird and steering has alot of wheel flex. I can float a bag no problem. It's truly a beast amp. You can see videos at official down for sound page on Facebook. Jason Klein. Very powerful amp and I love the bass knob with voltage and temp readings! Everyone has questions about the Bluetooth bass knob, my only recommendation is when you start your vehicle, let the amp properly power on before turn the bass knob on so that it can connect. 100% awesome amp
