I have a mrp m1000 amp running 3 alpine type r dual 4 ohm voice coil subs wired for 2.6 ohms after about 30-40 min of play at half volume the amp heats up and shuts down but it will restart when i shut the system down and let it cool now i have a 100 amp fuse on 4 gage wire and a good solid chasis ground and no abrasions on any wires. what should i do?

SOURCE: Blown fuses

This is a sign the you have poor voltage regulation. Which may mean that you are taxing the electrical system of your vehicle. I would suggest you adding a secondary electrical supply for you audio system. This can be done by adding an extra alternator and voltage regulator and battery supply. This will allow you to drive your audio system without having it (power supply) split between the vehicle and the audio system. The fact is your system is drawing to much current for the unit and your vehicle. You are blowing the 20-amp fuses which means the the amp is creating a currnet draw which is past the rated value of the fuses, which if done too many times could damage the power amp components in the unit. I would also check the ohmage reating on the speakers connect to the unit since you may have the wrong impedance which may also cause excessive current draw and actuate some sort of overcurrent protection.

SOURCE: 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

SOURCE: What is the best method to connect my speakings?

Wow, thats a really powerful amp! attached is a link to the user manual for the M2000 here. You want to follow example #4, this will wire you up for 4ohms total pumping out 1500W. Plenty of bang and bump as long as your airspace is correct! :) Also, make SURE you wire up that amp with 1/0 power cable and you can step it down to 2Ga. no more than 2.5' to the amp. The worst thing to do is under wire an amp. you will also want to upgrade your vehicle ground wire from the negative (-) battery terminal to the car chassis. I would go 1/0 with that new ground, you will drive up the impedance of your overall system if your ground is too small.
Hope this helps, -Remy

How do i get my 2 4ohm dvc type r's to 2 ohms for my mrp m1000 to get the full power?


ok its all in the way you wire them, just remember when you wire your speakers in series, the ohms build(add to eachother) which would make them total of 8 ohms, and if you wire in parrallel the ohm load cuts in half (2 ohms). So you want to wire them together in parrallel then run your wire to the amp. Just so you know though, if you bridge your amp, it will also cut the ohm load in half, so you would see total of 1 ohm which gives you more power, just make sure your amp is 1 ohm stable and your subs can handle it.

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

I have an alpine cda9831 unit with 10" subs. I have an alpine v power m500 independently running them. The subs will randomly cut off and on and the wires to the head unit have been checked for loose...


so you have already ensured that there are no crossed/loose wire strands.

you are running 2 subs off a single alpine mono amp.

if subs are 4 ohms apiece, you should be fine. if you have 2 ohm subs, or you have dual voice coil subs and you are running all the voice coils parallel, then there is your problem. you can have a maximum of a 2 ohm (2x4 ohm speakers= 2 ohms.) load with that amp.

ensure that the subs are 4 ohms apiece, and that you are not using dual voice coils. if the subs have 2 inputs (dual voice coils) then only use 1 input apiece.

if this is already taken care of, then your amp is defective.

How do i hook up the mrp-m1000 to 2 type r subs since it is a one channel amp? the subs r 4 ohms so it should work right?


hook the positive to positive and negative to negative on both subs then run wire to the amp the amp will see a 2ohm load

I dont know how to connect it .it is an mrp-m850 i tryed to connect it but it wont turn on


well u run a power wire atleast 4 guage from the positive terminal on the battery, then 4 guage to a chasis ground source, then a remote wire to the rear of your cd player that will kick the amp on when the cd player turns on... then for subwoofer wiring go to www.the12volt.com for sub wiring options... you need either single voice coil 4 ohm subs or 2 ohm dual voice coil subs to get the 2 ohm load to the amp so u can get the rated power out of it...

Hello smoot_dog,

Well, you did not specify whether you have the 2 ohm or the 4 ohm versions of the L7 and that will impact your choice of amps. But with 8 voice coils and 4 subs to work with, you certainly have lots or potential configurations.

If your subs are the 4-ohm version, I would recommend the Alpine MRP-M1000. Currently it is on sale at www.crutchfield.com for $347.00. With this amp you'd wire the voice coils in parallel (2 ohms), wire each of the 2 pair of subs in series (4 ohms), and the resulting pairs parallel to the amp for a final load of 2 ohms.

If your subs are the 2-ohm version, I would recommend the Rockford-Fosgate Punch P1000-1bd which is stable at 1 ohm. Crutchfield sells it for $349.99. With the Punch and 2-ohm voice coils, you'd series the voice coils (4 ohms), parallel each pair of subs (2 ohms), and then parallel the resulting pairs to the amp for a final load of 1 ohm.

Either of these amps will provide an honest 250 watts RMS to each L7. They'll not only rock your vehicle, they'll rock the pavement.

Dual voice coil wiring to class d amp


The easiest way to think of wiring voice coils and subs is this:
  • Two items of the same impedance in parallel = Half of the impedance
    • 4 ohms in parallel with 4 ohms = 2 ohms
    • 8 ohms in parallel with 8 ohms = 4 ohms
  • Two items of the same impedance in series = Double the impedance
    • 4 ohms in series with 4 ohms = 8 ohms
    • 8 ohms in series with 8 ohms = 16 ohms
In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:
  • DVCs in parallel, 2 subs in series = 4 ohms
  • DVCs in series, 2 subs in parallel = 4 ohms
  • DVCs in parallel, 1 sub = 2 ohms
With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.
