I have an jl e1800d amplifier that works at the first use of the day. When the car is shut off then started for the next errand the amp goes into protect mode. I let the car sit overnight and it will work the next morning for the first use of the day. The next time I use the car it's in protect again. The original output fets irf35n15 have been replaced with irf3710z about 6 months ago. I could use a place to start on troubleshooting thanks for any help.
