what's the best way to secure the amps to the floor under the seat?

don't wanna drill obviously...

thanks

 

put the amps in the space behind the factory sub, it works very well, lots of room

 

I put my amps behind the seats and my headend's brains under the passenger's seat. I pulled out the seat - four 14 mm bolts (IIRC) - and dropped the plastic areodynamics and popped holes though avoiding the "moving parts" (fuel lines etc.).

 

>popped holes though avoiding the "moving parts" (fuel lines etc.)

That's a good trick. Please clarify how you missed the critical parts with those bolts?

I mounted my amp to a custom bent AL plate held by the seat's base rails. So I didn't play drill roulette.

 

all I can say is WOW

 

the easiest wya to do it. Take a 1/4 or 1/2 inch mdf board. Put it under the carpet. Then screw threw the carpet into the board. It will keep the amp from moving anywhere.

I would personally screw threw the metal though.

 

The easy way is to crawl next to the car and put the fingers of one hand where you want to pop the holes and then reach the other hand under the car to "find" your other hand's fingers. If even you're bad at this you'll come within an inch of the two fingers meeting though the floor pan. There's not that much stuff going on in that neighborhood as it is one of the lowest parts of the car. The electrical wires are run though under the access plates on the far left and right sides of the car and down the middle under the console.

So you hug the car - meet your two fingers through the car and then look around a bit in that area for dangerous items. I found none at any of the four bolts. Bust out a carpet knife and cut though the carpet and insulation pad - otherwise the drill will knot itself up on the pad. Since the brains of the Pioneer AVIC N2 use an inertial navigation sensor I wanted the box attached firmly.

You can see the washer stack under the bolts to get the thing perfectly level.

 

^ +1. You can use small bolts and it's easy to avoid anything important. Here's the only pic I have of my amp:

 

Thanks for the great amp remounting tips! It is tight to maintain a 1" cooling gap between the sagging seat and ~2.5" tall amp. You guys make it sound trivial to screw the floor, so now I feel lucky drilling it. Do you smell fuel?

 

I'm not sure how tall my amp was but there is decent room. It still gets more air than if it was closed up in the compartment behind the passenger. I know someone who's amp will shutdown after long periods of use because it overheats in there. Under the seat gets decent airflow....but I think my fans are on the free sides.

Good luck!

 

My passenger weighs in at 92 pounds - figure 107 with the dog in her lap and there's plenty of room between my GPS brain unit and the seat.

Paul350Z,

Then your config would margin a 2KW amp.
Seat big amp folks need this bumper sticker:
"TOO HOT for Passengers with junk in their trunk!"

maximXL,

Fanned enclosures need to be power vacuumed periodically, as dust fouls them. Thus why I chose heatsink cooling.

 

thanks for the pics...

where would be the best place to mount a cooling fan... on the side blowing into the amp or on top of the amp blowing down...

or do I even need to do that... other than the rare long drive... I rarely drive more than 1 hour...

 

Well you need to move air. I wanted to take the warm air and eject it out of the cubby drawing cooler air in from the back of the car. Ideally you'd pull cool air in and eject the warm air out. With short little drives the concern is lower. Living in the desert like I do the concern is greater.

 

I remember my install looking like that...

I tried to mount my amps under the seats and use the cubby behind the driver as storage but that didnt work... It just got in the way when I vacuum ... Cooling is an issue in the storage area so I have a 120mm fan pushing war air out...
