[QUOTE="West1, post: 8560392, member: 586208"] 07 frontier, fsd 125.4 and saz1000.1 Amps are grounded to chasis and double din HU is also grounded to chasis. Ive had the system hooked up for a couple of years, no real issues aside from fsd amp having bad rca solder when purchased. About 2 months ago my system would randomly power down with HU still on (any volume), it would never power down on a rhythm (bump, brake, accelerate etc). The past week, it seems to shutoff at half volume and will not last a full song. I pulled on all wires to see if anything is loose, RCA's, ground, opened doors to see if 6x9 wiring was undone... empty. One by one I pulled the fuse to amps at the battery, still shuts off with either amp playing. Multimeter to XSpower3400 reads 13.86 at the lowest with music full blast. If I play the music under 40%, it seems to last longer. Any other suggestions? Mechman 270 is on order and on its way. The only thing I recently did was start my big3 and this was roughly a week ago. The only wire I replaced was the Engine to Chasis, could this be the culprit?? tyvm [/QUOTE]
