I have an Autotek SX2100 which states that it is True 2 ohm mono. But when I presented it with a 2 ohm load the amp played for about 20 minutes than it clipped. The manual says to use no less than 4 guage wire. I have 8 guage wire on the power and ground, could this be the cause of the clipping. I have the amp on 2 Kicker Comp 150w each 4ohm. Need some help

did you mean "clipped" or "clipped off altogether?"

In reality, that's a 200w (maybe) amp - there's no real reason why it should *require* 4g wire unless your battery is located across the county. If you overdrive it with lower impedances heavier wire may help with the clipping (distortion) but it's not going away. Are you sure it's rated to 2 ohms mono? That's a huge load. I'd think it'd be 2 ohm stereo, 4 ohm mono - something very different than 2 ohm mono.

It clipped off altogether.

You probabally just trying to make the amp produce more power than it's rated for. Turn the volume down, or get a bigger amp.

Clipped off, I am reading your posts, actually says to me: "turns off, then comes back on after a short period of time"... (Which, BTW is NOT clipping, it's an amplifier protection mode functioning as it should...) How close is that? If I am right on, it's because your amp is NOT one ohm stable, which is what you are asking of it by running it bridged into a 2 ohm load. You need to run one woofer to it, bridged... this'll be perfectly safe. Try it, and if it stops "clipping" as you describe it, then what I have described to you is EXACTLY the issue... The only answer then is a different amp OR different (8 ohm) woofers.

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."
