Default Need extensions for heater hose under seats

I'm putting my amps under the driver and passenger seats of my Forester, but the ductwork for the heater blows hot air straight onto them. Not exactly good for keeping them cool. I wanted to run some extension about 12" long for the hot air to pass over them w/o blowing on them.

It's tough to find the right size though, since it's pretty much a rectangular hose about 2 3/4"L x 3/4"H plastic hose. I only need about 4 feet of it, and the only thing I found that could work was at Lowe's and they wanted something ridiculous like $10/ft.

Any suggestions on where to find something like this? Dealer was no help, and a quick look on mcmaster.com didn't turn up anything.

duct tape the ducts closed. screw the people in the rear. jk. the amount of heat from those ducts is probably cooler than an amp running hot, and will still cool the amp down. don't worry. (unless the amp has a crappy heatsink design)

So what you're saying is for example: The amp is running @ 100*, and since the heater is only blowing say 80* on it, it's actually cooling it?

I suppose you're right, since after the interior warms up, the heater air T* is essentially the same as the surrounding cabin T*.

I hadn't thought of it that way. Thanks

assuming that the hot air from the heater duct is cooler than the amp is kinda running after trouble. it is sure than you can extend those for cheap, finding some 1.5" tube and connect them with duct tape. something like an vaccum cleaner hose will do the job pretty well IMO

we've installed hundreds of amps under seats, and an amp's heat sink can get up to 150 F. easily. if you've got 150 F coming out of YOUR ducts, you've got more than just audio problems...

I hear you Boost, but if I could find some cheap hose to stick on there I'd like to. Key word there is CHEAP!

NicEJ25, the shape is weird as I said before, so just finding some hose is harder than it sounds. Any suggestions?
