Sounds like you have a wiring issue.  Please describe your speaker wiring configuration, not just the ohm load you believe you have created.  What model numbers are the subs?

i agree i think you have your amp running at 1 ohm not 4 your subs are dual 4 ohm and if thay are you need to do a series parrallel combo to get 4 ohm mono wire the coils in series and the wires from the box in parrallel and if you dont get what im say go to www.rockfordfosgate.com thay have sub wiring diagrams that are very easy to understand

I'm running 8 guage power and ground. i don't kno all i can say is that they are 1000pk and 500 rms each, i got the bass on it about 3/4 up and i got the subs running 2 ohms but i think the amp is running 4, how can i mak the amp play at 2 ohms?

I dont know about your overheating problem but running that kind of an amp on 8 gauge doesnt seem too safe.  If i were u i would rewire the whole thing with 4 guage power and ground.  How big of a fuse are you using?  I think u should start from scratch with the sub wiring too.  Come up with an idea for a configuration then ask the pros if anythings gunna blow up.

I'm concerned about a couple of comments here.  First, if you "got your subs running 2 ohms" what do you mean by that?  Is each sub wired for 2 ohms?  How do you know?  How are they connected to the amp?  Second, the amplifier will operate into whatever load is presented by your speakers.  You don't "play it" at any impedence load other than what the speakers place on it.  If you wnat it to "run at 4 ohms" then you must connect a 4-ohm load to it.  This gets back to the first question, especially since your Kicker amp is stereo and requires no less than a 4-ohm load if it's bridged so you cannot "play it at 2 ohms" safely no matter what you do.  Thirdly, what do you mean you "got the bass on it about 3/4 up"?  What bass?  Do you mean the amplifier gain, or a bass boost?  Or the bass tone control in your head unit?

I can't help you until I know what you are doing and how your speakers are connected to the amp.  If these are questions you cannot answer, then you may need to seek ot some help from a pro in your area.

sorry i'm kinda new to this but let me explain.... i have the kicker i2302<600 rms> and 2 Volfenhag's<500 rms>. I followed the directions and hooked them up for a 2 ohm setup. Each Speaker is on each seperate channel. Each speaker is hook up positive to positive,vice versa, on each speaker, running it on a 8 guage wire kit. On my amp i have "bass", "treble", Frequency", And "mode" (off,hp,lp). My bass is turned up 3/4 and i'm playin the amp on LP. do that clear things up?? Also i gave a large 50a fuse inside my power wire.

OK, I looked up your Impulse 2302.  It's a 1999 model, so it may simply be overheating because it's old and worn out.  But Kicker made really good amps then, so it may still be OK.  It is rated at 360 watts per channel into 2 ohms, by the way, so I agree with the person who suggested you really need 4 gage power cable, although that is not the cause of your overheating.  I'd also suggest turning that bass boost DOWN to zero, by the way.  HERE's the manual in case you don't have it.

One last question: how did you set the input gain?

"gain" all the things i have on my amp is bass, treble, frew, and the other thing thats says OFF,LP,HP, but i have mt gain up about 3/4 and my treble all the ways down plus its on LP

OK... You are running the amp in stereo mode... HERE is the way you can wire it for that amp, in stereo mode. You want to look at the SECOND one - 4 ohms per channel... That's one of TWO options with that amp and those woofers... The second one is HERE. This is the one you will look at if you want to run the amp BRIDGED. Again, you want to look at the bottom diagram, only in this case you will be bridging the amp for a nominal impedance of 4 ohms per channel...

That's all there is. Select one of those choices, and you'll be all set.

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."

This is probably what's wrong, your gain is WAY too high.  You need to match it to your head unit output.  Start HERE.  Plus your woofers may or may not actually be 4 ohm loads, as they are a low-end brand.  Try wiring them for max impedence (voice coils in series) and see if the amplifier likes this better.
