ALPINE amps cutting out

My current set up consists of line signal converter (LC6i) matched up to two alpine V12 amps powering 4 alpine type r speakers, splits at the front coaxials at the rear.

my problem lies with this, when the sub is just about to kick, the 4 channel amp cuts out and only the sub produces sound.

Does anyone know what the problem to this is, or a solution to solve it?

any help would be greatly appreciated.

SOURCE: alpine v12 amp no power

its your fuse box. i would bypass the fuse box and wire this amp directly to the battery via monster cable. make sure you attach a 30wieght fuse to the monster cable that is running from the battery to your amp. ground the amp against the trunk. scrape the paint of a section and drill a hole in the trunk. use this for the ground for you amp. this will fix the no power issue.

SOURCE: want to bridge my alpine 3555 amp to run my sub.

I'm assuming this atleast a 2 channel amplifier all you need to do is hook the negative side of the speaker wire coming from the sub to the negative channel one. and the positive to another positive on channel 2. Should indicate on your amplifier channel one and two. most amps provide a diagram right on the amplifier over top of the speaker inputs. let me know if this helps.

SOURCE: why my alpine v12 amp is getting hot and melting fuses

You may have to big of a load. The speakers may be to low in ohms and the amp cant push speakers that low or there is a short in the wire going to the speakers

SOURCE: alpine pdx 1.000 keeps cutting out

You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

SOURCE: 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.

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.


Cheers,

Ok i got a mtx 12' 500 sub matched to a alpine mrd-m500 mono amp. The deck powers the 4 speakers, as i turn the volume up on my deck (alpine cde 100) the sub/amp cuts out at around volume 20-22 and E-3...


Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg

I have an alpine mrp-m2000 powering (4) alpine type r's. When I turn the volume up to about 2/3 of the way the amp starts to cut in and out. What could cause this? I was thinking it was just a tuning...


It sounds like the amp is at max power and is saving itself from frying.Different makers have different methods.If you want to you could call Alpine to verify it if you want but I bet they will say about the same thing.Good luck! Greg

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.

V12 MRV-1507 or Xplod? Amplifier - XM-ZR1252 good quality sound


Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.
