Alpine MRD-M605 - V12 MONO AMP 600WX1 RMS 2 OHM Car Audio Amplifier Questions & Answers
I need to know how
Hi there,
This really depends if your 10" subs are 4 ohms each or 2 ohm - for this exercise, I'm presuming they are 4 ohm each.
You already know your amp can deliver 600W RMS (@ 2ohm), so you need to be careful you do not exceed the maximum RMS input power of your subs.
Normally you would wire subs in "parallel", which would reduce the circuit load to 2ohms - however, the 600W RMS power may be too high for your subs to handle.
In this case, it may be safer to wire your subs in "series" - this will increase the circuit load to 8ohms, which will effectively decrease the amps RMS power output.
Cheers,
I have everything hooked up properly and the subs
yes, it sounds like you need to turn the gain up more than what it is. if you are certain that the wiring is correct and you have the source unit tuned properly there is not much more that it can be.
cheers
I wired everthing up and
check your ground, make sure you are going to a good ground, a bad ground is just like having the positive disconnected.
My alpine v12 turns on but no sound
no you don't have to hook up both of the power terminals. but should have it hooked up so you get the proper power to the amp. use a disubution block with two 8 gauge wires.
do you know if the radio's rca jack's are good? have you ever had another amp in the car? if it worked before try new rca's from the radio to amp. recheck all connections from amp to speakers and make sure no wires fell off.
How do you get it out of cur mode
Hello whatup_132,
If the M605 fails and displays "CUR", it means that there is excessive current to the amp.
The most common causes for excessive current draw is operating the amp into a lower impedance than it is rated to handle, shorted speaker voice coil(s), and/or shorted or grounded speaker wires.
The amp can operate into a load no lower than 2ohms. First power everything off and disconnect the positive amp power lead temporarily (easist way is to just pull the fuse). At this point you should ONLY have the ground and remote connected. Reconnect positive (insert fuse) and turn on the vehicle ignition and your head unit. If the amp still displays the "CUR" error, the output MOSFET's are probably defective and the amp requires repair or replacement. If it powers up normally, reconnect the speaker wires until you locate the faulty one, and then correct whatever is causing it.
Hope this helps.
I need to know how to remove the circuit board out
first take all the screws out of the back of the amp when that is done there will be about 6-7 screws holding the board in place. Then you have to remove all the screws for the mosfets on the outside edges of the amp but make sure not to smear any of the heat transfer tape or heat transfer gel that is under the mosfets and then you should be able to take the board right out
CUR is showing on the display
The amp will reset when you cut the power off to it. Disconect bat for 30 sec and reconect. But to be honist with u if the wire jumped out and grounded some how during a high level, there is probley internal damage done.
AMP POWERS UP, I CAN HEAR IT WORKING BUT THE SOUND
Hello korre,
Low output could be the head unit, the speakers of the amp itself. Start by isolating the problem.
1) Test the sub(s) on a known good output.
2) Input a known good signal. A portable with RCA preamp outs will work OK.
After you have eliminated the other components, troubleshoot the amp itself:
1) Check the onboard fuses. The M605 has 2 each 30A fuses just to the left of the power and ground terminals.
2) If it was just installed, then my first suspicion would be a problem in wiring. If one tiny little strand of your speaker wires comes into contact with another wire or ground point, it could present just enough of a signal path to ground out most of your power, and perhaps still allow the amp to seemingly operate normally (at least for awhile). Check power and ground too.
3) Make sure your head unit RCA's are plugged into the inputs and not the outputs.
4) Check the low-pass and subsonic filter settings. If low pass is turned all the way down, the amplifier would ONLY send frequencies below 30Hz to the speakers. Subsonic turned on and the low pass all the way down would effectively result in no sound.
5) Remove the top cover to access the mode controls and display. Check the input level.
If everything checks out, the amp probably has a defective component and needs factory/service center repair.
Hope this helps.
Installing two amps
No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)
Building Competition stereo's is a big hobby of mine.
