ok so i recently installed some stero systems and blew the amp fuses, i then replaced them and my system doesnt thump anymore. know any reasons why?
system:
mtx 2150x amp
2 12in punch speakers
system:
mtx 2150x amp
2 12in punch speakers
audio system problem

- Start date
does it have power? maybe those fuses went out too. check for the little green light on your amp? GL
im pretty sure its getting power. my amp has a red light i think that means its got the powerdoes it have power? maybe those fuses went out too. check for the little green light on your amp? GL
Red normally indicates protect mode. When the fuses that protect the amp blow, that means that there is a short. Either your sub is shorted, the + and - terminals are touching, or the amp is damaged.
so basicly my amp is trashed?Red normally indicates protect mode. When the fuses that protect the amp blow, that means that there is a short. Either your sub is shorted, the + and - terminals are touching, or the amp is damaged.

Your amp fuse is going to blow because:
- one of the hot wires is shorting out (power or remote wire)
- the main power wire is too small (causes the resistance to build up and the wire to become hot which in turn will cause the amp to go into safe mode or blow the fuse for protection)
- the ground wire is loose (if it is loose and the connection touches ground off and on it could cause the fuse to blow from the constant surges of power
- the internal power diode are bad or blown causing a short
I have NEVER in 15 years of installing car audio equipment heard of a sub causing the amp to blow fuses. That doesn't necessarily mean that it is wrong though. Just saying that I have never run into it or even heard of it.
Check your wires for kinks, snags, any insulation that is stripped off. Check the ground to make sure it is making a clean and secure connection. Make sure your power and ground wire is AT LEAST 10 gauge no matter what size the amp is. I usually run no smaller than 8 gauge. If everything is good try hooking up another amp to the same connections and see if it blows the fuse. If it doesn't your amp is shot.

12v+ constant or remote grounding would result in their inline fuses blowing, not the fuses on the amplifier.Your amp fuse is going to blow because:

Not necessarily. I have seen amp fuses blow before the car ones do. I have seen them blow before the big inline ones do. It isn't as common for them to go instead of the inline or car ones, but it does happen.
If there isn't an inline fuse or that one doesn't blow, it goes to the next one which would hopefully be in the amp. If the inline is a bigger fuse, it might have not let go before the amp one did.
It is possible that the amp is shot. Unless you have money to blow, I wouldn't write it off so soon. I personally would check it over really good before trashing it and buying a new one.
recheck all wiring for grounds i have done a few systems and its usually some thing small like that sub wires touching 90% of the time will be your problem
