Default Amp Overheating

Here is my setup:

1 2500 Watt Bass Inferno Mono Block Amp
2 12' Kenwood Subwoofers

Anything else about the setup please ask.....


The Problem:

After running my amp for about an 1 hour, it went into Thermo Protection Mode. I accidently brushed my hand on the RCA Jacks that went into the Deck, and they were hot as a ****. So I touched the AMP, and it was hot as hell.

Now, I did some searching, and have come up with a 2 areas that might have caused the overheating, but looking for expert opinions as well.

1. I have the Amp cranked to max settings. Why? Because when I first put it in, it didn't seem like much of an improvement as far as deep bass sound when I first put it in. I have been told this could over work the Amp/Subs, but I would figure with my setup, a 2500 Watt Amp and 2 12' 1200 Watt Kenwoods, that it wouldn't be to much of a big issue.

2. I oringally ran a 1/0 Gauge wire for Ground and Power for the Amp, however, when it came time to hook it to the Amp, I didn't have a connector the fit the 1/0 Gauge Wire and the Terminal both. My Dad decided to take a 8 Gauge Wire, and wire it to the 1/0 Gauge Wire, and then run the 8 Gauge Wire to the Amp, since it could easily fit without a connector. I read that this is like trying to drink and thick milkshake with a small straw.

However, after running my Amp for 15 Minutes, it got hot, not enough to fo into protection mode, but it got hot. I touched all the wires, and non were hot, making me believe the main problem isn't the power and ground wire.

Any ideas?

model of subs please. And how you have them wired.
The min impedance you should have wired to that amp is 2ohms. And you should also turn the "settings" down.

Check your impedance.

Its the Kenwood KFC-W3012. Has 4-Ohm Impedance. Do I have the wrong Subs for my Amp?

This is how I have it wired in the Amp.

- + - +

The book showed to wire them like this

+ - - +

But I went by the marks on the Amp.

I think I may have found my mistake. Am I supposed to wire up the 2 Speakers in the same spot?

Yes seeing as you have a one channel amp, they need to be wired to that one channel. If you wire them in parallel, meaning both + of the speakers are connected to the + of the amp and the same with both negs to the neg of the amp that means you'll have a 2ohm load.
