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.

Do you have the subwoofer amp connected to the pioneer thru pre amp connections; pre amp output of pioneer to pre amp input of Kicker amp. Page 10 of the manual explains how to adjust the subwoofer output. You can select the cutoff freq. that will pass to the subwoofer; The slopes don't match perfectly, but if you use the -12 slope , it should work fine.
80HZ same as kicker cut in freq
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....
Your SX650.1 is 2 ohm stable so wire the voice coils in parallel and the speakers in series, then bridge the amp. Keep your multimeter close. Don't forget to beef up your input wire size to 4 gauge on the positive and the negative side. The rear channel should be set around 80 Hz. Your amp has a variable low pass crossover (30-200 Hz) with adjustable slope (set at 12/18 to start) but you should be able to hear the bang and the boom in the sub woofer. This is only a starting point for the real ear tune. I turn the gains all the way down and give the head unit 3/4 volume, turn the gains up just before it starts to scream then fine tune the frequency (Hz). Do the front and rear separately by disconnecting the RCA's, and then together. Try and play a wide verity of music while your adjusting your amps, but fine tune what you like. I hope this helps to get you started, Ray
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.
It sounds like you may have the load impedance too low.
How many voice coils per woofer?
How many ohms is each coil?
If you have DVC woofers, are the coils for each woofer wired in series or parallel?
Are the speakers wired in series or parallel.
Let me know if you need me to clarify anything.
that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.
