Coming from the Skar RP 1500.1 The JP504 is next. Thanks JP! 5 JP1.2z3 Posted by Unknown on Aug 03, 2024 i was waiting to see a amp dyno video before i bought it but Big-D is taking his time on that so i pulled the trigger and got 1. it has a clip input indicator in addition to the clip out indicator, detents on the subsonic and crossover potentiometers' (nice feature) the manual is good it tells you the frq of each detent. be prepared it will pull some amperage D4S recommends a 190 amp fuse i blew a 150 amp fuse b4 i got a 190. 150 amps x 13.5 volts=2025 watts. it's a little BEAST....i will see it's true potential after i install my headway bank. practice safe sound!
