Daily Driver, Go Where I Want To Build

To install highline fenders, the amps need to be moved from under the steering column...

To under the seat.

After throwing away Jerry's fire extinguisher mount, start by cutting up half of an ill fitting CavFab cowl armor panel for the new amp mount to replace the plywood.

Under the seat is a button for the carpet and a plastic clip for the seat belt sensor. The amp mount will be clearanced to fit around these.

Using the cutoffs as a template, mill out a pocket for the seat belt sensor clip.

When the router bushing is taller than the cowl armor template thickness, throw a handful of washers under the router to create room.

Measure and drill a big hole where the button is.

Test fit.

Remove the seat. Drill the mounting plate for mounting bolts and mark the tub for nutserts. Drill and tap the plate to fasten the amps.

Reinstall the seat.

And hide a day's worth of work under a flap of carpet.

More nice work.
2 questions:
1) I see the particle board spacer but it looks like you potentially have metal in continuity from the amp housings to the tub via the screws? If so, any feedback? I did that with my amp and powered sub in the same location. The sub power was way down and I had with feedback that varied with engine RPM. Using nylon screws and rubber grommets solved those issues for me.
2) Why 2 amps? I'm thinking one for woofers and tweeters and 1 for a sub?

edit. 1 more question: Why did the highlines require amps to move from under the column?

1. That was a nice piece of MDO marine plywood. It isn't part of the underseat mounting.

2. This is what I came up with 9 years ago. I don't remember much of what little I knew about car audio at that time.

edit. Everything is affected by a highline install. And it doesn't always make sense!

The real reason is because the highline led to a complete reworking of the added accessory electrical system. During that process, I accidentally ripped out the ground for the sub amp. It's location under the steering column made getting to it impossible without removing it. Since the amps were removed and I didn't want to figure out how I got them in there, I decided to put them in a better spot.

Yeah I'm no expert on audio either. I did get some good help from folks here and some trial and error like my grounding problem. Sounds like your amps are better isolated within their housings than my components (y)
 
@jjvw, I used to have my amp under my driver seat, until, one day, crossing the river in the Rubicon Springs (very deep that year), water came up over door sill and blew out my amp. I have since moved it under the steering wheel column. Not sure how much water crossings you do in CO, but just be mindful...
 
I ran out of the Polyken high temp wiring harness tape I got from Blaine. The two rolls I found on eBay are larger than I remember. This may be a lifetime supply for me!
