i have just bought an AA0460 response class d mono block amp and i wanna hook it up to two cerwin vega XL-12D duel voice coil subs the subs are rated at 125w rms per voice coil so 250w rms per sub and they are 4 ohms per voice coil. i have these subs wired up positive to positive and negative to negative so they are 2 ohms per sub i then wanna hook these subs up together positive to positive and negative to negative so together they are 1 ohm total then wire them to my amp in bridge so positive off 1 channel and negative off the other channel would this work or would i blow my amp?
specs for my amp are:
Power/channel @ 1 ohm mono 14.4v = 1000w rms x 1
Power/channel @ 2 ohm mono 14.4v = 600w rms x 1
Power/channel @ 4 ohm mono 14.4v = 300w rms x 1

Thanx in advance, Jesse

It's a mono amp. There is no "bridge". I have no idea who or what the manufacturer of that amp is, but what fuses are in it?

Four 4-ohm voice coils all wired in parallel is 1 ohm. If the amp is reasonable or even half respectable, it'll be safe driving a 1 ohm load, as claimed...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Isn't it a 1 channel amplifier? If it has 2 positive and 2 negative speaker terminals on the amp, they are connected together internally. According to the specs you posted, the amp will handle a 1 ohm load.

The reason a mono block has more than one positive /negitive is to make it easier to install more than one sub when you have more than one lead running to the amp. As i am an idiot said above. It is connected together internally. The 2 positives and negitives are going to the same spot. So it makes no differance which positive or neg you use to hook up your leads on a MONO block
