Need Help with amp/subs

First off the amp is a kicker kx800.2 2 channel Kicker KX800.2 200W x 2 Car Amplifier - Hands-on Research at Crutchfield.com

subs 10" coustic Coustic CF1044 10" Dual 4 ohms Subwoofer - Sonic Electronix

So here is the issue, at first i had them hooked up at 4 ohm to 4 ohm bridged and had the freq db and gain all set at 3/4 and i was smelling a buring smell so i figured maby my wiring or i was pushing the subs to hard. Well i noticed when i took the power cable fuse out it was burning so i tried hooking it up as 2ohm to 4 ohm and i read that turning the gain up and the db down was better so i did but now my lights are kind of flickering and the amp is shutting off for a second then turning back on it seemed alot louder like this and i dont smell that burning anymore either
im thinking maby it is my wiring to, i got that 1200 watt kit from walmart with i think a 4 gauge wire and it comes with a 80 amp fuse for it
also i was wondering what should my freq be at if the amp is 50-200 and my subs are 36-150, if there are 2 subs should i just max it on the amp?


btw my car is a 2000 gtp
 


LOL..you thought you were pushing the subs too hard so you dropped the impedance of the sub? That sub is only capable of being wired at 8 ohm or 2ohm. I would go back to 8 ohm. If your amp is shutting down, its probably drawing too much current. Or its overheating. It sounds like you're pulling too much current through the wire and its popping your fuse. Most 4 gauge wires can handle up to a 125A fuse . (Depends on how well the wire is built) If your fuse is burning and not blowing, you should look into getting a better fuse and holder. Like an ANL fuse and holder. For the frequency on the amp, I'd set it for 80hz or below.

what do you meen the sub is only capable of being wired to 2 ohm or 8 ohm? no its not its capable of 2 ohm and 4 ohm and im running 2 of them btw

Edit: look at the post for the subs there is a wiring diagram for 2 subs with 2 channel amp those are the ones i tried
 
ok so i just realised my wire is only a 6 gauge so thats probly my issue so i guess my question now is what ohm should i wire it to be safe with a 6 gauge wire or does it not really matter and i should just keep it turned down
 
My bad....I thought you said you have one sub. I would definitely bump it back up to 4ohm. And get a larger wire. That amp wants to pull more current than the fuse on that wire can handle. The worst thing that will happen if you continue to run that wire, is your fuse will keep popping. Just dont put a fuse in that line larger than 80A. Anything more and the fuse may not protect the wire, which means fire. Sounds like you may want to drop down to a smaller fuse anyway, if you already smelled burning. A popped fuse shouldnt burn.
 


ya i rewired it to 4 ohms bridged and im going to go see if i can pick up some 2 gauge wire tomarrow, if i run it at 2 ohms with the new wire, and the subs being 800 max 400 rms each and the amp being 400 at 2 ohms would it be safe? or should i just keep it at 4 ohms which would be 200 going t each sub
 
Yes. With a 2 gauge power and ground line, 2 ohm will be safe. The amp will heat up faster at a 2ohm load, so if you are driving around at high volume for long periods of time, it may get too hot and cut out until it cools back down.
