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.

Hello Briankt69,

Ot two issues, First the AMP is going into a protection mode this means that it is drawing too much current. As netrecov said you need a capacitor, this will oppose the rapid current draw, by allowing the voltage to remain constant. However I would also sugget that you rewire the setup to manufatures specification and make sure that all grounds and supply leads are installed properly. Taking into mind the the 4awg wire has less cross sectional surface than the 2 or 0 AWG wire causing it to have more resistance this is power loss in this case (follow the specifications).

I hope this helps

Thank you,

SOURCE: Not enough bass

its prolly the deck, did you try turning the alpine's input gain controls up...

its not the wiring, if the wiring was insuficient, it would just melt...

you might also see if you could adjust the bass frequencies or crossover frequency, the crv might just have a different resonant frequency then the rav 4

You need to check the Fuse on the Power Wire and check the ground wire to see if has loosened up. Also check Power Wire as well.

Hope you see what you are your looking for! Good Luck!

SOURCE: Alpine mrp-m450 Amp won't stay on

Sounds to me like it might be the remote turn on because the first time i installed it, it did the same thing, and i found out that there is two blue wires coming out the stereo, one with a white stripe, i connected it to the blue wire, and it didnt work, then i connected it to the blue and white wire, and it worked. Well hope this solves your problem, goodluck.

sub spec 250watts per coil you should be just fine I have 2 typr 15s on orion hcca 2500 1 and it kicks a$$ thats 1000 watts over the rated limits of the subs only shut the amp down once these subs can take a lot more power than they say just use your common sence with the volume and gain levels

I have a Alpine MRP-M350 amp and then I have 2 10 Kicker Freair F10A Subwoofers. What's the best set up for this combo?


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

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.

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

I hook up my alpine amplifire and the red light for the fuse protection comes. on what could it be?


It is either hooked up wrong or the wire you are using is too thin. Be sure to use the proper gage wire for the output of the amp.

Weak rear left amp output?


hey whats up bud i got an ALPINE V-POWER MRP-M350 these amps are great go to a walmart od any music shop buy a set of R.C.A cables that plug into your amp than that Ys off to a single connection its a male cable that run a set from the back of your cd player heres the trick ONLY PLUG YOUR BLACK COLORED RCA INTO HEAD UNIT MAKE SURE YOU RAP THE RED ONE WITH TAPE OR GET A RUBBER CAP TO PUT OVER IT SO YOU DONT GET ANY STATIC FREQUENCIES COMING OUT OF THE RED ONE THAN RUN THAT SET TO YOUR AMPLIFIER AND AGAIN ONLY TIE INTO THE LEFT CHANNEL OF YOUR AMPLIFIER.... Hope you know wnat i mean by that Y adapter ther is 2 prongs that tie into amplifier than it splits into 1 were your rca cables will plug into just that one thats how you bridge these confusing amps.... TRUST ME BOTH SUBS WILL SLAM HARD I RUN 2 JL AUDIO OFF OF MINE NO PROBLEM....

Weak output from sub..


The woofer was not demagnetized.

If one signal cable is damaged, it could reduce the signal getting to the amplifier and could reduce the output.

Plug one RCA plug in at a time to confirm that both are working properly. If one is lower or not working, the cable may be defective.

If both work properly, double-check the settings on the head unit (sub-out, bass, crossover frequency...)
