I've had this amp for a few months, and it ran my two kicker CVR 12's just fine, i could crank it loud and they would sound good, amp would never overheat. but this past weekend, it starts cutting out when it gains volume or the bass hits, and the led goes from green and blends to an orange and red then cuts out for a few seconds, sometimes doesn't put out at all. The wiring is fine, it just cuts out for no reason.

How I tune:
turn amp all way down or disconnect rcas for now, turn up stereo to a song with some bass you listen to and crank it as loud as you would (not max about 3/4, use this to tune inside speakers (don't have bass maxed/distortion...)). Now dial in amp: turn up a bit probably to 1/4 or so then tune frequency I'd usually say around 100hz, then adjust gain again to where it sounds good...be easy on them for awhile to let them break in (don't blast them all day!). Usually bass boost is only 1 frequency with a curve (40hz or something)...so I try to not use it much....
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 !!!
Ok, first you need to have at least ten gauge wire cause the amp needs agility of juice. Next you want to find a good ground to frame of the car (if its wrong you'll hear road noise through speaker.) Next look on the fire wall and find the terminal that has other wire coming to it (one from positive to the amplifier on battery the rest out top other you want to put an inline fuse to amp.and have ground write other side of the cart than the power. run write to amp then to your speaker I believe I made it is simple for you as possible good luck
Use the above site for several wiring schematics on dual voice coil speaker hookups. It will show how to wire for different impedance.
Also, I think the CVR 12's come in 2 ohm and 4 ohm impedance. See if you can check yours to determine which you have....
You need to use 4 guage or larger wiring with this amp. Also you need to make sure the power wire and ground wire are the same guage.(thickness)
The ground wire needs to be as short as possible from the amp to the metal of the car.
Make sure you are using a 14 guage or larger speaker wire form the amp to the speakers.
