Will my crescendo 1000c4 amp that could power 125w x4 channels at 4 ohms, 250w x4 channels at 2 ohms, 500w x2 bridged at 4 ohms, 250w x2 bridged at 8 ohms be able to power my front and rear doors Alpine SPS-600c component speakers 80 watts and 300wRMS SSA DCON 12 inch sub. And if so how should I go about doing this ?

the speakers are fine just keep the gains low. is the dcon a S4 or D4?

Id run the front stage off the amp and then bridge channels 3 and 4 for the sub. Run the rear speakers off headunit power.

Its a D4 and my HU is a pioneer deh 4300 ub that puts out 4x50 but the speakers are 80 ? how would I make it so the rear speakers dont burn out my hu ?

no it just means your speakers will handle 80 watts, they will take what the hu provides powerwise and not stress the hu

RMS is not a requirement its perfectly fine to under power them and its also ok to over power them. Over powering them takes a bit more skill and knowledge, but it can be done.

I had my comps hooked up to my deck and my deck ended up getting really hot and shutting down whenever I went past 30 volume its currently at a repair shop Why would this happen ?

Your headunit puts out power between 4 and 8 ohms. Chances are you could be running at less than 4 ohms.

How would I fix this issue if I were to have the rear speakers running off the HU ?

You would have to check the wiring with a digital multi meter to verify they were wired at the right ohm. If not you would have to wire them right.

CEA2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)

Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)

Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)

is what the specs are for the head unit. would 22 watts rms be enough in the rear to not get burnt out by the speakers? and would sound quality suffer badly from the weak rear speakers in the car ?

Sound quality wont suffer. It will pull your front stage to the front. Your headunit wont be burnt out by the speakers. You have nothing to worry about.

think of it more like this, the speakers are being fed 22 watts, not the other way around (ie. the speakers are not trying to pull 80 watts from the hu).

I understand this explanation however I just don't understand how my pair of comps burnt out my radio and I had to take it to a repair shop. And when it worked I had to have the bass at negative levels and the volume down low. Unless it truly was a faulty mechanical issue but it seems improbable..

The only way your speakers would harm your headunit is if you wired them wrong.
