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

Check your ground

this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

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

did you put the ground loop isolator near the amp end and the deck end of the rca or near the EQ if you have one

you amp is 2 ohm stable

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.

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.

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.

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.

check your ground and make sure you battery power is connect properly
