Too much heat?

I have been thinking of new ways to do my install, since I want to try to keep everything hidden or hard to get to because of thieves. I've had my DEI 1100d for 2 years now and have not even turned it on yet, since the sub I was going to use on it got a hole in it and I didn't want to fork over the money for the new sub or subs. I bought 2 subs Power Acoustik 12" subs for a friend of mine who was supposed to pay me for them and then backed out so I've decided just to use those for it. My question is I have a coupe and I was thinking of putting my DEI 1100d and DEI 150 on my backseat in the trunk. Then I was going to have my box containing my 2 12"s up against the seat or close to it. Would that be too close for those 2 amps right there? Also I have to decide where I'm going to put the cap and distribution block.Integration20

Should be fine and just make sure the cap is within a foot to the amp and the distro block could be anywhere i think---- 1996 Chevy S10 ----
