Hi Big Nick,

 

Sounds like you have got almost all the good out of those Subs. You can find the screws you need at almost any hardware store or Auto parts store. The light is becase you are dloading the amp with low OHMS.  You may need use one channel and Run the wiring like written blow to get the power problem to disappear.

 

S1+ = Kicker comp cvr sub coil 1 positive

A+ = Amplifier Positive output.

 

 

A+ to S1+

S1- to S2+

S2- to A-

Could be the power supply or output stage electrolytic capacitors.
Possibly breaking down/drying out inside.

SOURCE: MRV - 1507 Question ...

The MRV-1507 is a two channel amplifier, below I've pasted important info from the manual:

Battery Lead (Sold Separately)
Be sure to add a 80 amp fuse as close as possible
to the battery’s positive (+) terminal. This fuse will
protect your vehicle’s electrical system in case of a
short circuit. If you need to extend this lead, the wire
gauge should be AWG8 or larger.
MRV-1507 ... 80A amp fuse

Power Output: RMS Continuous Power (at 12.0V, 20 Hz to 20
kHz)
MRV-1507
Per channel into 4 ohms ......................... 150W, 0.08% THD
Per channel into 2 ohms .......................... 300W, 0.3% THD
Bridged into 4 ohms ................................ 600W, 0.3% THD

You can find a manual for this amp here:

SOURCE: Mrv F345 power cut out and now the screen flashes blue

disconnect all of the speaker wires at the amp and turn your system on -if the amp stays on then you likely have a roasted coil in one of your speakers somewhere and causing a short which is shutting your amp down into protection mode-if the amp wont stay on with nothing connected to it then you have probably roasted something inside the amp and uhhh good luck bro

I have an alpine mrv-f307 4/3/2 channel. I have it hooked up to 2 12in Kenwood subs. Right now standard 2 channel each sub having their own. I heard doing a series hook up and bridging the subs to the amp ...

Bridging an amplifier refers to combining the power of two channels to run one speaker at higher power. If it is wired correctly, your amplifier is running with 4 channels bridged into 2 speakers now.

My mrv f345 amp reads CUR on display screen and has no sound.

That error appears usually when the speakers (especially subs) aren't getting the current they need from the system. Check your wiring and make sure you're using the appropriate gauge wire. Too small of a gauge in wire can cause this.

Amplifier displays "CUR"

Hello anwbrown,

The "CUR" display means that the amp is drawing excessive current and the protection circuit is activating. Too low impedance or shorted speakers will cause the amp to draw excessive current.

The Alpine V12 is a Class D mono amp with only one set of speaker outputs. All versions, M301, M501, and M1001 are only stable to 2ohms. Assuming that all 6 of your connected subwoofers and speakers are 4ohm and they're all connected in parallel, the amp sees a .67 ohm load, far below it's rated impedance.

When brand new, the amp could probably operate at low to moderate volume levels without drawing excessive current. But as electronic components age, their tolerances change and they become less able to withstand excessive current or mismatched impedances.

I'd get a 4-channel amp and drive the 4" speakers off the front channels and the 6X9's off the rear channels. And just power the subs off the V12 making sure that they are connected to show a minimum load of 2ohms.

Hope this helps.

Wiring door speakers

Just make sure that the speakers are the correct impedance and properly rated. If not, the amp can be damaged.

Over heating

you trouble shoot the problem by opening unit and force-powering fans to test for overheating during "being used loud for a few minutes". Read the fans' label for proper voltage to apply and proper polarity. I am guessing the fans will run on car battery voltage of 12 volts. Also, attempt to close up the unit to simulate real conditions. There should not be fuses for the fans. If unit is now cooling, then look for faulty thermistor, which turns the fan on during rising temperature. Once thermistor is located, a fast test is to "jumper" its two wires to simulate turn on.
