Ohh I have mine in the trunk. But thats just me. Mine are WAYYYYYYYY to big to fit under te seat.

 

im not sure if amps under the front seats do get cooled better than in the trunk.. i know the trunk doesnt have any airflow, but there is a lot more space, and under the seat, how much air flows down across the floor? plus the space is so small, and the seat could act as insulation.. so.. anyways.. i wouldnt do it.. plus its gotta be a pretty small amp to put it there doesnt it?

honura - you know where to buy EV's down in nyc?

 

I had mine under the seats and in the trunk. Havent had cooling problems with either. Under the seat even with the car parked in a lot during 100+ degree days in the California valley i had never had the amp shut down. The only problem might be that if the amp is a bit too tall the seat may rub on it when its moved. Overheating was never a problem. My amps were about 250 watts each.

 

if possible in all cases, leave the amp face up not side way. heat rise!!!!

 

I justed screwed it down. If you really want to get technical, you can screw the amp onto a thin 1/2" partical board and then screw that down. But test first (i.e. make sure the seat slides fine WITH someone sitting in it) before screwing the amp or board down.

 

I'm lazy and this is from Crutchfield and if they say it's okay it should be:

Finding the right spot
An amp can be securely installed with just a few screws. But since amps can be sensitive to electrical and motor noise and because interference from the amp may affect your radio reception, try to mount it at least 3 feet away from the receiver. Good locations include:

* Under a seat
Pros: Closer to the receiver, so you can use shorter patch cords and signal cables. Closer to the front speakers, so running wire to them will be easier. No cargo space sacrificed.
Cons: You may have to remove the seat to do the installation. Larger amps won't fit.

* In the trunk or hatch area
Pros: Lots of room for large amps. Near the rear speakers or sub enclosure.
Cons: You sacrifice some cargo space. Longer wires and patch cords required.
Note: When working inside the trunk, tape over the latch, so you won't become trapped inside accidentally. [I found this hilarious but had never thought about it either and am happy I read it]

Keeping your amp cool
Something else to consider when choosing a mounting spot: Amplifiers produce heat, and the heat must be dissipated efficiently. The amp's cooling fins absorb heat and radiate it into the surrounding air. For the cooling fins to operate efficiently, they need a few inches of air space around them. When mounting the amp on a side wall, try to position it so that the slots in the cooling fins are vertical.

Amps should not be mounted on the bottom of a rear deck with the fins facing down because the heat will radiate back up into the amp. Leave yourself enough room on either side of the amp to make all the wire connections and adjust the controls. If you have a subwoofer box in your vehicle, you can mount the amp on the outside of the box.

If you are mounting the amp to the vehicle's floor, check beneath the car to be sure your screws won't puncture a brake or gas line.

 

In addition amps use fins to dissipate the heat so airflow isn't really needed as much as airspace. Like Crutchfield advises as long as there is a few inches of space around them the amp will be fine. I know this from being a computer geek, nerd, whatever, I built mine. There's enough air movement in a car, even without A/C or windows open, to keep the heat moving away from the amp(s) under seats.

 

Mines under my passenger seat and its been doin fine for whille now. Its a 600 watt Alpine running 2 rockford fosgates...no trouble at all.

 

usually all that can fit under the seats are mono class D amps. In my F150 supercrew i have a JL e1200 (200 watt mono class D amp) under the passenger seat, but in my accord i have a JL 1500 watt 3 channel amp pushing 3 JL 12" W3's. the 1500 watt amp is HUGE and the mono class D amp is very small.

 

You're talking bout sub amps, most amps to power regular speakers aren't that big or that powerful so they fit fine.
