I have a kicker zx300.1 mono sub woofer amplifier. It puts out 300 watts RMS at 2ohms. I have two kicker comp C 12" (rated 150 watts each) subs in a ported box in my trunk. The amp is mounted to the box and is powering the two subs wired parallel to them. I listened to the subs at a moderate volume all the way home from school today which was about 15 minutes. I had the gain set at about 65%. Everything worked fine but when I got out of my car to view my subs I touched the amp and it was a little too warm to touch. I could keep my hand on it for a few seconds before it was too hot to touch anymore. Also it was about 90 degrees F outside today maybe that was part of the reason. Anyway, I was just wondering if its normal for an amp like this to get warm. I'm probably being too cautious and all but I feel its better to be safe than sorry when dealing with expensive electronics like this.

Check the temperature range for the amp in the instructions manual. If the overheating persist move the amp to a more ventilated area, if not install a pair of fans available a@ radio shack.

If your subs are wired in parallel your impedence is too low. IF yo have the dual 2 ohm models, you are at 1/2 ohm, if you have the dual 4 ohm models you are currently at 1 ohm. If you have the dual 2 ohm model the correct way to wire them is as follows: take the + from the amp and wire it to the first + of each sub, take the - from the amp and wire it to the first - of each sub. Now you have a + and - from each sub left correct? take and wire the + and - of the same sub together and you will now have a 2 ohm load on your amp. This hold true if you have the dual 4 ohm model also, you will just have a 4 ohm load at the amp instead. If you need more detailed advice contact me at hondab16tuner@yahoo.com

Rick D is acceptable, amp isn't made to do 2 OHMS bridged. Unbridge it and placed a MONO enter to the amp and placed one voice coil consistent with channel. IF no longer you will BURN THE AMP UP OR UNSOLDER CONNECTIONS interior the AMP. i'm hoping its no longer on the ingredient of the bass as while the amp heats up and rattle the solder loose interior the amp. top now its kicking off to tell you something is faulty.

Amps heat up, make sure the cooling vents are unobstructed. You said that the amps were mounted on the box - make sure the box is not placed where the amp has contact with anything else

also how or where do you have your amp mounted........because some may not pay attention to the fact its not a good idea to mount a amp unside down for the simple fact heat rises......and the amp should have a couple inches of "breathing room"

Check the output impedance of the amp. 8 ohms, 16 ohms?
Check the input impedance of the speakers. Should they be hooked up in series?

It's about time Electhrolite answered a question right...I gave him a thumbs up.
