Will 5000 watts rms be too much power for this underseat fox box ported enclosure?

[Mack187Murder]

I have a 18" in a 5.5 cube box with 5000 watts on it. It takes up a third of my backseat and have my seat removed for it in my 2012 sierra denali 1500. 

 

I wantwd to keep the amp and get this 4x8" sub enclosure for under my seat and throw 4x1000 watt rms 8" sundowns in there.  

 

Im pretty sure the fox boxes are 5/8" mdf. I dont see any interal bracing. I suppose i could throw a couple in there maybe by screwing them in and then just using some liner to touch up the screw holes? 

Any thoughts?

That box is designed for SA-8s as a result the X subs are going to find themselves in a too small box with low port area and tuned too high, surely above the 36Hz specified as driver displacement for X subs is larger, maybe it will get to 38Hz or more and could experience some port noise.

 

Used to a large box tuned very low you will definitely notice a loss in bottom octave bass.

 

Regarding to your question, you can always strengthen the box but if it is made of cheap thin 5/8" wood then it is not impossible.

 

Lastly the pre cut sub holes cannot fit X subs, you will have to work on the holes.

 

Overall that box seem expensive and not adequate for the subs. I would lift up the seats and do a proper custom enclosure for those subs and even then you probably have better bottom octave bass right now than you will ever get with some 8s.

You dont have 5000 watts on anything. FYI

@Joe X

 

Awsome thanks joe will maybe think about building my own then. 

I have removed a seat already to fit my 5.5 cube box. Were having another child and need the seat room thats why i wanted an enclosure underneath.

 

For conversation sake. If this was your truck. And you could only work with the space underneath your seat. And wanted the biggest bang and lowest frequency possible with an enclosure like that. What might you suggest?

You dont have a clue what i have stud FYI.

The amp im currently using (cus the last one i had went snap crackle pop) dynos over 5400rms @1 ohm on 14.3 volts. Thats not my issue tho. Issue is how to put 5000 watts underneath a back seat if its even possible. Which it sounds like it isnt.

I would definitely look into seat lift kits to fit a box of proper size for those subs, make that enclosure with 3/4" birch wood, dual layer for the baffle, proper bracing inside, specs are 4 cubic feet net 64 square inches of port area tuned to 32Hz, I believe the sub cutouts need to be 7.34".

 

Depending on how much space you find to work with I could fine tune that spec to increase output and low end extension as possible.
