I've got a 1500w inverter under my back seats and I've never gotten it hot enough to even turn on the cooling fan. Most amps would probably be fine unless they're being driven HARD constantly.

Airflow down there actually isn't that bad, and there's surprising airspace.

Certainly anything I would want to install would be fine in that location, leaving only the matter of making a box to mount the sub without being intrusive.

I'm just a fan of having things tucked away in such a way as to retain a stock-looking construction. Be they electronics, aftermarket parts, or even cupholders, I like it when it looks like there's some apparent design to my stuff.

This is a dilemma I also face with the supercharger for my 240SX.
Those older Alpine V12 amps get hot, even with their internal cooling fans. There's a lot of amp stuffed into those small footprints. I wouldn't put them under the seat or try to hide them; they need all the air they can get. The system in my car has the larger versions of those amps I have in my Jeep and the 4 channel gets hot to the touch; it's out in the open.

Drove to the beach and went fishing with my oldest. Not the best of days, but I did get a nice seat trout.

Yeah I have an old alpine v power something or another in mine. Used to overheat under the backseat and shut off. Now I moved it to the cargo area, it's higher up now so it's less likely to get fried going into water.

Went out and tested my flex after rough country 3.5" lift under 2" BB. Now need extended brake lines and to hammer down the fender pinch seam.

They designed it perfectly, that's why they included a little plastic cover to provide blissful ignorance .

Just did some shopping for control arm bushings since all of mine are pretty bad. I already have a set of stock front CA's left over from my last ZJ. Trying to decide if I should just replace the bushings in the rear or do it the easy way and get new arms. Going with bushings would cost half as much, $54 for them vs $109 for new rear CA's. That's a nice savings but I know I could have all the arms swapped out in 2 hours. I feel like the pain of replacing 8 bushings might not be worth the $55 saved.

I lost that plastic cover a long time ago wheeling. What's the point of it?

I'd do the arms and not fight with the bushings. I did mine on my ZJ, in my driveway, one arm at a time without even lifting it off the ground. The rear went really quickly. The front gave me some issues because the axle moved. Not messing around with the bushings was worth the slight extra cost. Those control arms live on in a buddy's ZJ now.

I had done the rears on my last ZJ and it was quick. Unfortunately I put those 4 new arms on maybe a month before it was totaled. I wish I could have salvaged those and a few other things before having it hauled away. Yeah I'll probably just go with new arms. If I end up needing adjustable's within the next year I can always resell these for half the price and make up the difference.

So mount your sub amp there, crank it for a half hour on a hot summer day, then see if you're convinced.

I believe the point of it is to hold in salt and moisture to provide a thoroughly rusted track bar mount.

It did a perfect job at it....

No probs, I'll just build my own bracket and raise it's mounting point by 3" like I did on my wife's ZJ's D35 last summer.

Better add some gusseting to that thing. It wont take long before the factory welds fail and the whole bracket pulls away from the axle. No different that running the aftermarket brackets they sell over the counter.
