Question about Alpine MRP-M500 Car Audio Amplifier

1 Answer

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 causing these problems. The set up worked fine for 2 1/2 months. Thank you for any help.

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 all alpine speakers,deck,amp, and subs. My subs were working for about a year until one time i started my car and they keep cutting in and out .. at times they will work but then they cut off...


Sounds like blown subs, in the process of completely dying out, or a loose wire, possibly inside the box or from the box to the amp. Have your subs tested at a sound shop, or using a multi-meter, check for resistance across the sub terminals. An open line indicates a blown sub.

Best amp for Kicker Sub


Hello dalex7,

The Kicker 08ZX400.1 would be a great amp for your subwoofer. It will work into a 4ohm load with no problems.

But you can buy an amp with more power, looks better, has a smaller footprint, and cost less than the 400.1. I'd look at the Alpine MRP-M500. Take a look at it here at Crutchfield. The M500 is also easy to install, runs cool, and is very efficient.

Hope this helps.
