Could be the power supply or output stage electrolytic capacitors.
Possibly breaking down/drying out inside.

My kicker 12 inch cvr's arent hitting as hard as they should


amps and wiring kits are very optimistic on the output. If you want proper wire, buy some welding cable "0" or "00" guage. That solves the power delivery. Put a 1 Farrad (or more) capacitor near the amp, that solves the surge power issue. Make sure the box is suitable for the subs. Lastly I'd say do some research and find the right amp that can deliver the clean, huge current required to move some serious air!

2 kicker cvr 12's in prewired kicker box with 1 wire terminal, kicker cx1200.1 amp. Whats the best way to wire this combo?


Well you really can't run both speakers on one term. because you will over heat the amp , unless your amp is rated at twice the capability of your subs , Then if so , Try positive to one sub , then neg. to the other sub , then bridge the remaining positive to the remaining negative terminal , But it is really best to get a two channel amp for your subs !!!

I have 2 18" kicker


First you need the OHM rating of the subs. Most of the time its on the box or the magnet on the back of the subs (normaly 2ohm 4ohm or 8ohm) And that of the amp. Most amps are 4 ohm output if its a 2channel and 2ohm output if its a mono. You NEED to know these cuz wiring it wrong can blow channels in your amp or cause it to cut "in and out"

Over heating problem


"how do i made amp ohm instead of 4"
What?
I think you're asking how to make the amp 2 ohm. If your 12's are already wired for 2 ohm, just connect the 2 leads to the bridged terminals on the amp. There will be 4 connections on the amp. One for each channel. Usually, the two outside terminals (one positive and one negative) are the bridge and it'll be noted with a line painted on the surface above the terminals. That's all you have to do.
If it is overheating, you should put cooling fans on it.
