Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

Why do you need a diagram, + from the amp go's to the + on the speaker and the same with the - . Make sure you get these right, if you get them wrong it will sound poor.

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'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.

Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.

this isnt a complex problem but both units may need service
