I have had a pr1000 memphis amp on 2 rockford p3 12's for 7 months now. No problems whatsoever, this past thursday i am driving home and jamming as usual. The amp turns off and does not come back on when i turn off radio. I check it out and all four 30 amp fuses are blown. When i attempt to replace it blows all 4 again. I go this morning and buy a U.S. Amps Merlin MD3D and it works great for 20 min, then it blows all six 40 amp fuses that it has.. i have a Kinetic HC2400, and 2 gauge power/ground. It is very perplexing to me as to what is happening. i had a guy hook a meter up to it that told me when the unit was clipping and adjusted my max volume to that. Have not had a problem til thursday and it is working at all.... actually started smoking when i replaced fuses on the merlin. Anyone encountered this problem before? any help would be greatly appreciated... i also have a 240 amp breaker up front on car battery
Sounds like a bad ground possibly. Have you checked them out? Have it grounded directly to the frame? It definately sounds like a resistance issue though. Something to do with wiring somewhere along the way. Also do you have the electrical to support a MD3D? That could maybe play into it.
A ground could have came loose over time. Retrace the wires and make sure everything is secure. If they're not already, do a direct ground to the frame in the rear.
I did have the kinetic grounded and the amp ran from that.... rained all day yesterday and could not troubleshoot but today I am going to skip battery all together...I just have to get amps repaired on Monday to test... will keep you updated
K so I found my problem....all wires and the subs were good.... when I hooked up RCA jacks it went into protect..... now it plays fine with a new set of RCA. ...I have never heard of that before but oh well. Back to bass!!!!
