    what size are your power and ground wires??

  • TDWPgtp May 11, 2010

    is it a dual 2 or dual 4 ohm voice coil sub? have u tried replacing the fuse on the power wire, as sometimes the soldering melts, but the fuse does not appear to be bad. does it light up all?

You need to check the Fuse on the Power Wire and check the ground wire to see if has loosened up. Also check Power Wire as well.

Hope you see what you are your looking for! Good Luck!

I have a alpine MRP-M500 amp connected to 2 10 inch comp kicker subs. The problem is the subs rattle and distort. The subs have been tested ok and all the wiring has been tested also ok. What could be...


Any time that there is a rattling sound from the subs, that indicates that they are probably blown. How were the subs tested ok? If the resistance of the subs is still close to OK, that is good, but it doesn't necessarily indicate that they are working properly.
Try using different subs at a lower volume, or turning down the gain slightly.

caution

About Power supply wires (MRP-M1000 only)

• 21mm2 is the minimum power and ground cable size

that should be used to connect this amplifier. The

length of these cables should not exceed 1m to assure

safe operation.

• If the length of the power and ground cables exceed

1m, or if you connect more than one amplifier, a distribution

block should be used with 33mm2 or 53mm2

power and ground cables depending on the length

necessary. Ensure that you install a correctly-rated

in-line fuse on the power cable near the battery positive

post.

I have an Alpine MrP-M500 that is not giving off sound. The light is diming, and blinking meaning it is in "safemode." ive done everything, new fuses, ground is good, wires are good, sub is good. I got it...


yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

Equipment not turning on!???


Have you tried checking the remote wire yet? Because it could very possibly be that. Without a remote wire hooked up, you cannot get any power. Try that and see if it works.

I hook up my alpine amplifire and the red light for the fuse protection comes. on what could it be?


It is either hooked up wrong or the wire you are using is too thin. Be sure to use the proper gage wire for the output of the amp.
