SOURCE: MRV-F540 Amp shuts off when turning music up

The amp may have defective components, but it is still salvageable. first of all lets discuss what is happening. The amp is cutting off because of excessive current flow. which means one or some of you components have become thermally sensative. You can find out which components they are by using a can of cool mist or any other component cooling spray. this will allow you to find the problem quickly. Now in addition to this you may have to forego the tricks and do some real troubleshooting. Get a schematic of the device and try to take voltage readings to see which components are at fault.

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-

How do I bridge this amp to run a single sub?


  • To bridge 1 sub with a Alpine MRV-100M amp you run the negative and positive wires coming from the speaker to the outside terminals on the AMP respectively.

I honestly don't have a solid answer for you. I can say check your fuses. Check your battery to amp wire. And also check your ground. Make sure the fuse on your amp is also not blown

How to convert from 4 ohm to 2 ohm car amplifier


All amplifiers are rated by the manufacturer as to the minimum impedance they can be wired to and still operate effectively (or at all).
All amplifiers are different - and there are some not stable at 2 ohms.

In theory - you are changing the amplifiers LOAD - not the amplifiers ability to withstand a lower impedance.

An amplifier that is wired at a 4 ohm load will have approximately HALF the power of the same one wired at a 2 ohm load.

If you post your amplifier make/model I can tell you the spec's.
If you're wondering what voicecoil wiring configurations will give you a 2 Ohm load... I can help with that as well - Simply post your make/model of the subwoofers.

Thanks for using FixYa - a Very Helpful Rating is appreciated for answering your FREE question.

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:
