The aluminum bracket I made is still holding up, which is surprising since it's mostly held together with duct tape. This weekend I was actually planning on getting some plywood and redoing the mount and some wiring.

Is yours just flat bar/straps? Are you looking at a benefit other than cost with a plywood upgrade? The durability question that I presented was in reference to the OP's plywood mount. I would like to assume that it's the same as day one, but that's tough to say with the humidity and water exposure of some areas. I'm all for cheap, but if there's a better/best way to do something...that's what I'm using.

The plywood seems more secure. My mount is just flat bar and some 90* angled stock that I cut up and is held together with self tapping screws and duct tape. It's just some scrap I found in the garage. One end is screwed to the firewall the other just sits on the HVAC tube with only duct tape holding it down. It's pretty ghetto.

Have you seen the skinny pedal mount? IIRC it's made out of aluminum. It's where I originally got the idea and didn't want to pay 60$ for it.

Nope, I'll fire up Google and see what it is. Thanks.

Size matters

Excellent thread.

However, size matters for this under dash location. I purchased the Alpine MRP-F300 to drive my front and rear speakers and it's too big for this location or any other location under the dash including side walls or firewall. It also won't fit under the driver or passenger seat. I have a 2005 Wrangler with the seats that raise up and forward to allow a rear passenger easier access.

It looks like it should fit under the dash but the heat sinks push against the heat ducts that run behind the kick plate and that's before I have the board mounted on it. So if you're thinking about this install, find a smaller sized amp. I'll need to return this one.

Dimensions are 9 3/4 x 11 and it's too big on both dimension. It looks like an inch less on both dimensions is the maximum you could go.

I returned the MRP-F300 and purchased the MRV-F300 instead (more money...) but this amp is 8x8 in size. After hours of trial and error I got it to fit. It misses the break pedal by about 1/8 " and leaves a 1/8" air space by the kick plate heating channel. Very tight fit but it works. I also came up with a fastener that worked far easier than a nut and bolt which proved to be impossible. I found a large butterfly toggle that mounts to a 1 inch bolt. This worked perfectly. Once you get the bolt threaded, it will spin and lock up on the side of the steering column so you can just tighten down on the bolt without struggling to keep the nut from spinning or fabricating something wierd to hold it.

Polk Audio speakers 4-6 front, Polk 5 1/4 in the pods and a 6 inch Quadratec direct replacement sub in the console and keeping my stock head unit. Sounds fantastic and painfully loud.

I also just used this space for my Kicker Amp...(very small amp and plenty of space) Thank you OP...Question? Where did you guys fasten the ground wire? I think I either need to sand down the spot I used more (in the engine bay) or find another spot. The amp didn't work this morning but later in the day it worked. Thinking the ground has bad connection. This powers my kicker sub...Center console. Thanks!!

I know this is an old thread... but I'm trying to mount an alpine PDX 400.4 under the dash and am about to try zip ties. Got the amp mounted on a board with the lag screw going through that little convenient hole under the steering column. Even went out to buy a special wratchet 7/16 wrench. But can figure out how you got the nut started on that bolt so deep in the dash. Even tried gluing the nut in the wrench to try and get the thread started. I guess being an installer for 13 years gets you certain super powers that the rest of us mortals just don't qualify for..LOL

Thanks to OP and those that contributed to this thread. I stood on y'alls shoulders and tweaked your designs to mount my new amp. I am attaching a few images that may be helpful to the next person doing this project. They include some dimensions of the board and bracket. The amp attached to the board. The board and amp installed. And a closeup of the bracket installed on the steering column bolt.

EDIT: The bracket hole spacing is 15cm (not mm).

Very nice, I still get a kick out of knowing I have an amp installed in that location.

Great 1st post, welcome to JF!

Also it amazes me how much smaller amps have been getting since this thread has started!

In the very near future, I will be attempting to install both a 4 channel and a mono amp under the steering column using the DIY Skinny Pedal bracket.

Kenwood KAC-M1804 Compact 4-channel Amplifier
Kenwood KAC-M3001 Compact Mono Digital Amplifier

I took this idea and let my imagination go where it goes and came up with this

Here is my version with two compact digital amps. 4 channel and mono.

The plywood panel is about 8x7".


A t-nut is added to the plywood panel. I used a right angle pick to mark the hole while holding the panel in place. Also, because so many have mentioned concerns about heat, I raised the amps off the plywood with washers to add a bit of breathing room.


The panel is hung off of the steering column with a single bolt through the existing hole.




It's very secure and has no effect on the tilt steering.
