PPI PC2600 gonna kill my premiers?

[substance 10+ year member]

i recently got one of these and i built a box for my 2 premier 4 ohm dvc 10's. its running at a 4ohm mono load. the amps rated at 600x1 @4ohm but it also states that it doubles its rated power at that load. (so 1200). i have the gain all the way up, and im not really hearing any distortion from the subs, but i have a feeling since they are rated 350 rms its just a matter of time before the subs go out on me. what do yall think? also if i was to put a different set of 10's to this amp, what would be recomended? i wanted to try the premier spl's but then again i wanna save some money. Elemental designs? looking for some serious spl here.

Turn the gain down, it isn't a volume control per se but you can use it to limit power going to your subs. Power levels isn't nearly as likely to toast a sub as clipping the amp is. High gain settings is how you clip an amp. High power, combined with clipped amp = dead subs. Turn down the gain and as long as you don't go crazy with the volume knob, the subs should be fine.

the amp never heats up though

Just because its not heating up does not mean that you gain isn't set too high. The 4 ohm rated output of that amp is only 600 watt when bridged. Set your gain properly, there are plenty of threads on here telling you how to do it and your subs will live a long happy life.

Those amps run fairly cool, besides they have built in cooling fan. I have a pair running my 12L7's and they do very very well...

Well i adusted the gain correctly, And had these guys bangin real nicely, but i wired them in series, i had 1 - and 1 + going into the box and bridged them out to 2 - and 2 + but one of the sets of wires was too long. So I blew the ever living shit out of the sub hooked up to the shorter set of wires, it was getting more power. I mean i really blew it, if i turn the sub upside down i can hear something falling down from the magnet to the cone. and when i push down on the cone it grinds... But i got some premier spl 10's for a cheap price (160 a pair) and hooked them up today, they are soundin pretty sweet...

I doubt very seriously if the shorter wires had anything to do with it. The difference in resistance would be negilible. More than likely just a defect in the speaker...
