I am so impressed with how incredible these subwoofers perform running 2 RP2000.1d (8 per amp @ 1ohm each amp) 151.2 decibels SPL termlab measurement. 4th order wall, 1996 Jeep Cherokee.
I have 3 dual 2 ohm subs on a taramps smart3 in a mini truck custom ported nerfed enclosure tuned to 32hz and they surprised the fuck out of me. I am upgrading to the evls next. I have a 370 mechman elite, 2 runs off skyhigh, xs 3400 uprfont, 2 3100s rear and a bank of caps.
