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.

I have two type-rs hooked up to a mrp-m1000 and its not hitting hard at all! but when one is hooked up it hits harder than two... so is it the way its hooked up or do i need another mrp-m1000 amp? or can i...


If the speakers are rated at 500W or greater, then you'll need two amps to get their full potential. When you connect two to a single 500W amp, each speaker only gets a max of 250W. Also, check the ohm rating for the outputs of the amp and the ohm rating of the speakers as well. Unmatches speaker/amp impendence also results in poor performance. If you connect two speakers to one terminal, the total impedence of the speakers falls by 1/2 (two 4 ohm speakers wire together will result in 2 ohm impedence). So, if you have an amp rated at 4 ohms, you could connect two 8 ohm speakers to a single output. Hope this helps some!

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.

Amplifier wont move subs


I dont know if this will help you but start at the deck and make sure that the outputs(RCA) arent crossed over to highpass and do the same at the amp make sure that its set for lowpass- set half gain -bass boost half gain- subsonic minimum - If that doesnt help try using an i pod with an adaptor that you can play it right into the amp this is to see if you are getting signal from the deck to the amp if it doesnt work with an i pod or mp3 plugged directly into it then you may have got you a blown amp going on- good luck with that
