Question about Boss Car Audio & Video
Everytime I turn my music up the amp cuts off
The first thing I would check is how your speakers are wired to the amp. Multiple speakers wired in series or parallel will change the overall impedance that the amplifier "sees". If your impedance is too low (let's say 1 ohm) and your amp is only stable to 2 ohms, the amp will shut off to prevent over heating and damage. Hope this helps.

SOURCE: protection mode?
What guage of wire are you using to power the amp? Should be 6 guage or larger. Do you have a good ground to the frame of the car (metal inside trunk area)
Is the amp new or used?
Also your speakers could be shorted inside. Use an ohm meter to check them. They should be about 4 ohms useually. Test them UNHOOKED from the system.
Try different spakers. If you cant solve the problem, the amp might be damaged.

SOURCE: my amp wont go past protect mode
I had the same problem. be sure to change all transistors cause once one goes the rest useally goes right along with it... replaceing one or two transistors will not do the trick, cause once you power up again the rest of them will go, & you will have to repeat the prosses

Have you checked the REM wire, if it is the wiring may have gotten fried.
Or you may need to get new parts replaced within the amp.
Both issues happened to me.

if your amp is overheating your sub is needing to much power that the amp doesnt have.
if its cutting out and the red light comes on you need to check the wiring. nothing not even the tinyest speaker wires can be touching.
proper wiring would be your best bet.
but i would upgrade amps.
cheap bang isnt reliable.

Your amp is probably OK. The volume is either set to
high or the speaker load is to low of an impedance. Remember 2, 8 ohm
speakers connected is the same as 1, 4 ohm speaker. Another possibility is that
you do not have enough battery power coming to the amp itself. A simple rule I
use is take the watts and divide by ten, that will give you an approximation of
the amps needed on a 12 volt system. This takes into account some of the
losses in the amp, but it is only an approximation. For example 300 watts RMS
is 30 amps, which will require a number 8 wire to keep the losses at a minimum.
You can check wire drops on the web.
