20 Most Recent Alpine MRP-M350 Car Audio Amplifier Questions & Answers

I usually run an extra pair of RCA's when I do an install. This way if you have a problem with one you're already set or if you upgrade you won't have to tare you car apart again.

Check the ground wire. If you have a bad ground, you will not have any speaker output. The ground should be solidly connected to the vehicle chassis in a paint-free location. Check the live power wire as well, it should be connected directly to the battery. Then check the speaker leads to the amp. They should not be in contact with the vehicle chassis, or (at the input slots on the amp) with each other.

From the plus(+) of the speaker output on the amplifier run a cable to the plus(+) on the voice coil of the first subwoofer then follow thru with the same cable to the plus(+) of the other subwoofer.
From the minus(-) of the speaker output on the amplifier, run a cale to the minus(-) of the first subwoofer then follow thru with the same cable to the minus(-) of the other subwoofer.
This will make your amplifier run @ 2OHMS and provide you with 350 Watt RMS which will work fine even if you run your subwooffers free air(without a box))
hope this helps

You dont specify the model or RMS power of the subwoofers so i am not sure if that power is RMS or maximum.
If it is RMS, then a BiG no would be the answer. Even though the MRP-M350 will drive the subwoofers and will give you a fair sound as well, it not drive both of them effectivley. After all it's only 350WATT (the amp)RMS trying to push a 2500 RMS (the subs) target, so do the maths, is that a fair fight?
hope this helps.

not really it will under power the sub and probably damage the amp it will work but the current draw from sub will damage the amp, one or the other i sugest

Hook up the MRP-M350 to one 4-ohm sub, and you get 200 watts RMS; connect a second 4-ohm subwoofer and the power output increases to 350 watts! All that juice means that your subs won't just be loud, they'll sound clean and thumping.

The easiest way to accomplish this is to get a kit from your nearby stereo shop that will convert your stereo signal from your factory unit to a pair of rca outputs .You can get them from walmart if you feel up to the task of wiring it up. You will still need to get an amp wiring kit as well from there its just a matter of running power ground and rca cords also a remote lead to turn the amp on and off-you can do that from the fuse box easy enough.-after that just run your speaker wires from the amp to the speakers and your in business.hope that helps

use one of these in parrallel on the speaker output, and connect the RCA-RCA on the amp, should work fine

probably a blown capacitor open it up and look at the capacitor see if any one of them are curvy on the top blowend

hi there
its up to you the remote wire is just another power wire.....the remote wire can be by passed but every time you turn off your car you will need to unhook the 12v amp power wire from your cars battery (if you decide to do it this way)..........or you can hook up the blue wire from the back of your CD/DVD unit what ever you are using and every time your stereo turns off your amp will too..........
hope this has helped

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Let me know if you have any other questions.

you dont have it bridged right your dropping your ohms down way to low.. when you go to bridge your amp you have a negative and a positive on your amp thats it i have an alpine v-power mrp-m350 i think there identical should be but anyways you have to buy a Y splitter there RCA JACKS its has the 2 ends that plug into your amp than ties into a single one its a male or female adapter the place were your gonna get it w know the trick of these amps when bridging is only keep your left channel cable plugged in to your cd player i think its white colored dont plug the other one in rap tape around it or get a rubber cap and put over it.. run your RCA cables to your location of amp location and do the same just tie that into your left channel and tape or get a rubber cap to put over the other one i wish i could draw you a diagram of it hard to explain when typing it if you have a cell phone or house phone i would prefer you calling me from a cell so i dont get charged a fortune my cell number is 1814-594-2667 call me i will get it working for yeah hope to hear from you soon my name is Brad

first off you should have installed an inline fuse block that fuse will pop first an inline fuse is cheap go to a wall=mart it will run you around 10.00 that gets mounted under your hood cut your power cable in half the one part of the cable should be cut 12 inches that will tie into your possitive terminal on your battery after that is all tightened to your battery you will strip about an inch of coating offf of your power wire tie that into the end of your fuse block make sure it is tight than do the same to the other side just measure from there to your mounting spot for your amplifier and tie your power cable into your amplifier use 8 gauge power and ground cable... your problem with your amp is that you burned up a couple capasitors or even a resistor i just fixed an amp that both fuses were smoked just tear your amp apart look under the control board you will see were a sauder joint is cracked those capasitors and resisters are very cheap there made out of ceramic i just got done repairing my friends amp works like a new one.. good luck if you have problems or w you get it fixed email me..
