1 Answer

I'm helping a friend service his Alpine mrp-m1000 amplifier. So far I found burn spot on an integrated circuit it has a KDY that reads up and down the it reads 600K then underneath that number it reads 849. I know these are part numbers I just would like to fix and and rock out, or is there a replacement part. Have picture of part available

    there should be a location number on the board, example: ic 801. what is it?

  • garyyounger Oct 11, 2010

    It's a diode or a transistor. I'm thinking it's a diode because it's on the dc to ac portion of it. If I had a schematic of the logic board or a service manual I would good.

I have the MRP-M1000 amp. I want to hook up 2 alpine subs to this amp. Which alpine subs would be the best for this amp? Please be specific with ohms and watts.


Your best bet will be to wire 2 subs in parallel to the amp. Each sub should be rated for at least 300 watts rms at 4 ohms. This will give you a total impedance of 2 ohms, and your amp will put out 600 watts rms at that impedance. That way, each sub will receive 300 wats rms. I would not recommend wiring subs in parallel, as you will need two 1 ohm subs at 300 watts rms, which are harder to find and will be more expensive. A parallel circuit is the most efficient way to do it.

I have the Alpine MRP-M1000 amp. I want to use 2 subs with this amp. Which Alpine subs would work best with this amp?


this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

Will this amp push 2 2000 watt subs?


hope this helps.

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.

There is a smell in my car every time I play my system for long periods of time. Its a burning smell. Everything is wired correctly and I have a separate battery in the back of my car to power my subs. I...


The problem could either be the amp over-heating or the subs could be over-heating as well. One of my friends owns an Alpine MRD-M1005, and one day they decided to clean it inside and out and realized they had some burnt spots on the circuit board, although they never smelt anything burning, and the amp still works fine.... As for the lights dimming you should probably buy a power Capacitor, atleast a 1 Farad or larger.

Hope this helps.

How do i install mrp m1000 to two type r 12s step by step.


Hello chadbcavanau,

See the link here for a step-by-step install with photos and amp wiring diagram.

First you need to purchase an amp wiring kit (minimum 4 gauge power and ground). If your vehicle is equipped with the stock radio, you'll also need to purchase a line output converter (LOC).

Hope this helps.
