I need to know how to hook up an alpine v12 amp 2 ohm i have two tens

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.

2 12" subs + 600W amp. Turn on, goes boom once, then red light

Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

My subs/amp are not working

when you car is running, it charges the battery somewhat. So the voltage problem is not a problem. The red light means the amp is going into ''Protect Mode". This usually happens when something is wrong with the amp. Usually the amp is getting hot. Check all of you connectiong and check the final impedance of the subs. Make sure the amp can handle the impedance of the subs. If you need anymore help, message me.

One speaker is working more than the other

I would replace the wire your sub is hooked up to and try hooking up the sub that was sparked to the opposite channel on the amp to make sure the amp is not the culprit. Also switch RCA cables L to R, R to L

I need help

Most of the time if the red light is on the amp is no blown but some times it does this cause the subs are hooked up in the wrong way. If the amp is only 2ohm stable and you hook the subs up to it at 1 ohm than the amp will not work so I would check this frist.

Music not playing from subs

Do this for the sub amp...

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Red light

something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.

Plz Help - unknow problem

Sounds like a short circut protection on the amp kicking in. It sences the power going to the drivers and cuts itself out before damage is inflicted on the subs.
