Question about Alpine MRP-F300 Car Audio Amplifier

1 Answer

Alpine mrp-f300 cuts sound off when volume is turned up.

I have an alpine mrp-f300 and infinity reference 6020cs 6 1/2 and infinity reference 4" 2 way speakers and a pioneer DEH-P4000UB cd player installed on a 2005 subaru wrx wagon. when i adjust the crossover and gain the sound cuts off. i swapped channels and put the 6 1/2s on channel 3&4 and the 4's on 1&2 and bridged both of them. for some reason the 4's are louder than the 6 1/2's and the sound just won't get right. any suggestions?

The problem when someone become a car audio fanatic is, we want to hear BOOMS but we are not sure how many watts the amplifier can handle, besides that theres one very important thing that most of the installers don't know. its called ohms law (not a joke) that law tells you everything about how to measure the ohms marked on the speaker labels and also the way that you connect the speakers (theres two models; serial circuit and parallel circuit)

every single movement that you make on the connections tells a different story, and if you over load the amp it will auto protect.

i suggest you to set the level at least at 60% so you don't make any damage to the internal components, and don't forget to study ohm's law because a really professional installer knows it and well, they do the matt to get the best performance.

Power to amp no sound


Test your subs on another amp....If they are fine then try running different rcas in your car from the stereo to see if they are the culprit. If still no sound probably your output on your amp is gone.

It sounds like the amp is at max power and is saving itself from frying.Different makers have different methods.If you want to you could call Alpine to verify it if you want but I bet they will say about the same thing.Good luck! Greg

I just got the MRP-F300 amp installed today and the rear-left speaker completely stopped working shortly after the installed. There is no cracking, hissing, or any noise whatsoever coming from that...


not usualy if you were running them before without the amp the speaker could have still easily blown. with just the deck running the speakers you can clip the sound and damage the coils hook up and amp then you force the power through an already damaged speaker finishing it off try another speaker. or if it was bought used amp may be no good the previous owner probably noticed it cutting in and out and sold it before it fried. or the deck is old and yes it is a possibility the radio went bad. if you used cheap rca cables yes it could be bad as well.

Cuts out at high volume.


and that's fine with the ohm load. But if you have them wired all together or in parrelel it changes the ohm load. You need to wire them all together in parreallel or in series to get the correct ohm load. Check the wiring diagram at www.the12volt.com to see what your options are. the mrp amps are at a 2 ohm load smallest stable so makesure they are wired above or right at
