Low clearance Amp install with fans?

Hey guys (new here) Intro
I just got an 09 TRD Sport Access cab and have been piecing together a system.
So far I have:
Alpine SPR17's for front doors (still looking at coax rears)
Powered by an MB Quart DSC 4215 amp
Tied to a Pioneer Premier DEH-600ub head unit
Dynamat everywhere
Low end is (hopefully) going to be a Boston Acoustics G510-44 sub.
I already have the sub, still need an amp for it, still need to fab up the box, still need a place to put it, etc (details, details)


Aaaaanyway, Space is real tight in the Access Cab and I can't really get the 4-channel amp under the seat (at least not easily) like I had hoped. So, I'm hoping to stash the MB Quart amp in a custom box where the current "Flux Capacitor" stock subwoofer lives. Since it's gonna be boxed I was thinking I could run a pair of small brushless 12V DC fans for ventilation.
Am I out of my mind or could a couple fans give enough cooling if there's 1/2 or so of clearance around the amp and the box is open at bothe ends?

Many thanks.

edit:
If this has been discussed I apologize. Tried searching for "Fan" "fans" etc and didn't find any threads.

 

What i've always done with installs like that is use 2 fan sets (depending on how many amps, how hard you plan on driving them, etc)... one at the top for 'intake' and another set of fans at the opposite end of the box for 'exhaust'. that way you ensure a solid flow of air around the amps at all times
