SOURCE: Amp goes into protect mode.
I would definately suspect wiring. If you can use a volt meter. Put it on the b+ to ground and see what the reading is should be 12+ then try the ground to remote wire should be 12+. If it drops below 12 volts when car starts. Recheck wires for loose connection. Also double check the wire you have the remote wire connected to. You might even want to disconnect from the amplifier and use a jumper wire from the positive terminal on the amp to remote on the amplifier and see if it stays on then. If it stays on you will have to find the loose connection or find a different wire to get remote power.

SOURCE: amp blowing fuses
The amplifier probably has shorted output transistors.
Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

Ok a few things to check here. So get a checklist lol.
Is the amp well ventilated?
When it goes into protetion mode is the amp HOT? like too hot to touch?
Do you have the GAIN maxed out? Turn it down
What are the gauges of your ground/power cables?
A bad speaker or speaker wire can cause this also.
Incorrect wiring of speakers like 4ohm speakers wired in parallel connected to bridge.
Inadequate alternator or battery in car
Does your system have a Capacitor? If not get a nice digital CAP they aren't too expensive.
