PA1500 Nakamichi 1200 @ 1 Ohm Keeps Blowing Fuses

[eldefontes 10+ year member]

Hey all,

I've got a PA1500 nakamichi powering a SSA 12" ICON at 1 OHM. This is the second time the fuses on the amp have blown, the 6 15A fuses on the back. I have a 100A fuse hooked up right next to it and that has not blown.

This has happened at very very very random times, all amps are adjusted correctly using an Oscope, no clipping.

08 Acura TL -> Stock HU -> ARC ALD -> Mosconi 6to8 -> Mosconi 120.4 -> Arc SE 2075 -> PA-1500 Nakamichi

I've watched the battery with a DMM and I barely see it drop below 13.3v. I need assistance!

Thanks for the help.

Were those amps 1 or 2 ohm stable....thought they were rated @ 2 ohms..

Here is the manual. Says 1200 @ 1

I'm about to just start looking for a SAZ 1500...more reliable and will probably be cleaner.

Looking for immediate help here please...

just blew 18, 15A fuses. Replaced the 6 that were blown, turned car on, Vol 8, let speakers play for about 1 minute, walked away, came back and sub was cut out.

Replaced the 6 15A fuses again, drove around for 15 minutes and different volumes, 5-35 (35 being max without HU clipping) NO FUSES BLEW. Just got home, let the GF take the car out, she just called me and said the sub cut out again....
