Question about Alpine MRP-M450 Car Audio Amplifier

1 Answer

Power turns on briefly

It's not a wide setup, amp is going to 2 woofers like it did in my previous vehicle.

HU powers up w/car, amps power light briefly turns on and then back off.

Not sure whats up...

Tested power - 12v
The light turns on which kind of tells me its getting signal from the HU, ie remote wire.

Suggestion?

Sounds like a protection problem. A relay may be stuck, or there really may be an internal problem you cannot see. Take it to a shop to have it bench tested independent of your vehicle.

The amplifier may be going into protect mode (even briefly) because you are driving them too hard. Back off on the volume and see whether the problem goes away.

If the lights on your sub box aren't coming on it's either your ground of power wire came loose or the transformer blew. As for the subs, make sure all the connections are good, especially on your RCA wires. If your amp is getting power, then check your speaker connections. Also, make sure to turn the gain know up. The gain knob is located next to the RCA input on the amp. Let me know if this helps.

Subwoofers produce very high levels of vibration due to the intensity of their job. But the problem you are facing is a problem with the power pack. The power pack on the woofer is not supplying properly therefore the light/volume not coming on when the unit is unplugged and replugged. This also affects the woofer when you turn the amp to high because as a result of the power coming from the amp not being properly distributed instead of the power which flows into the woofer from the amp is not distributed accordingly it could blow the woofer so before it gets to that stage the unit shuts down.
All you have to do is get an expert to help you get and replace the power pack.
Hope this solution has been helpful?

If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.

Car subwoofer just past half volume cuts off the amp


Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

Protection light keep coming on


Make sure your head unit is off.

Reset the amplifier using the manufacturers specified method. Usually this is just power down briefly and then back up. I usually pull the amp fuse and make sure all LED's on the amp go out. Wait 10 seconds, and then put the fuse back in.

If the LED comes back on when you reconnect power, without the HU being on, you've got a bad amp.

If the LED does not come back on after reset, then check for short circuits on the speaker leads. Still leaving everything off, from the amp terminals, remove both wires to a specific speaker and check for shorts.

Amp turns off


Sounds like remote turn on wire is bad. If using aftermarket HU, find another location to power amp. Try the the power antenna wire on the HU to run the REM.

Jl audio with 2 12kickers cvr


it sounds like you don't have enough power to run the amp, or else it is a built in (MOSFET) overload device inside the amp. the woofer is from your discription blown. when you choose a amp and woofer you need the woofer to be able to handle more watts (MAX) than the amp can give or you will blow every woofer you connect up. you can solve the power outage by fitting a "CAPACITOR" which stores power and provides it to the amp as and when it is needed, or you will need to install another battery for the amp alone.
