Question about Alpine MRD-M301 Car Audio Amplifier
Now amp is always in protect mode, reading CURR on display. With or withourt RCAs connected. I do not smell any burnt components. I also cannot visually notice any burnt or defective parts inside amp. What could this be, and how can I fix it MYSELF. I am pretty good with a soldering iron!
If it reads current, that means protect mode. Unhook all wiring for a few minutes then connect them. it should start working. If the polarity is wrong, it overheats, or impedance is too low (under 2 ohms); the amp will display CURR until the problem is fixed. I'm sure it's not blown.Good luck.....Log in to crutchfields site and type 500mrdm301 in the search box/ that will give you the amp and you can download the pdf for the owners manual.

Check all fuses on the unit, pull them all.
look for a way of resetting the amp.
LEAVE THE MAIN FUSE OUT TILL THE INSTALL IS COMPLETE!!!
that way you wont short a screw driver across the terminals on to the chasis.
