2 things, grounding and fan placement

[USMC_Metallica 10+ year member]

k first thing, my sub amp is sitting on top my sub box. the PGR terminals are on the right side and its grounded on the other, kind of long for a ground which does that have something to do with it overheating rather quickly? i could shorten the ground by maybe 1 to 1 1/2 ft if i ground it on the other side. but i dont have a drill so i want to ground it in the same screw that my components amp is grounded. will this cause problems having a 400w component amp and 1400w sub amp grounded to the same spot?

ok and the fan placement. while i battle to keep my sub amp from overheating, im debating where to put the fan i have. most of the top is perforated. would it matter if i put it at the perforated end so the air could flow through the amp and hit all of the electronics or should i put it at the other end where its actually getting "too hot"?

its fine to ground to the same spot, in fact its usually recommended.

As for fan placement, you should get more than 1, for an intake and exhaust, and run them through the heat sink fins. Or, if you know what your doing, you can attach it to the internals of the amp

there are no fins, only perforation for a length of the amp then just chrome.

in fact, here it is:
