hi all
well this is wat i have : 1 280watts rockford powering 4 mb quarts speakers and 1 250 watts rockford powering box. my 250 watts amp seems like its not working.. no idea in how to fix but im almost positive my amp is no good(dont know how to check but the LED light is off?and plus i tried to plug the other amp's power cord into this one and it still didn't work)...what do u guys think because in my sisters car she has a sony mosfet xm450 and another sony 400 watt thats in no use..should i swap that with my blown amp , although the watts are alot higher would they produce better sound??im a noob and tell me what you would do in fixing my amp or should i swap and use my sisters?

is the sony mosfet xm450 a good amp??

check your fuse on the constant line, mkae sure the 12v remote turn on line is showing 12 volts, dlb check all the fuses in your amp are still good, and make sure your ground is still connected.

 

yea check the fuse, im almost certain its the fuse. who did the install. usually there is a fuse to prevent any kind of burn out in the amp
