2014 SEL Aftermarket Sub+Amp Install

Recommended Posts

Okay so I asked about a week ago if it was possible to do an aftermarket sub and amp install on a model that didn't include a stock sub (Without SONY). I didn't have many replies, I only assume because it's quite the task to do an install without a factory sub being in place already. But I have done it:

The sub was calling for an enclosure of .50 cubic feet minimum and the stock cubby hole measured only .30, so I had to modify it:

​I used a plastic epoxy to secure the initial half of the box:

 

 

Then I used fibreglass to patch the large hole, this was my first time working with it:

 

 

After hardening for a couple days I used silicone to seal the holes:

 

 

I then used a undercoating spray (Rocker Guard) to seal the rest and provide some sound proofing. The smell from the fibreglass was horrendous so this helped:

Next on the list was to route the main power wire for the amp. I found a nice large grommet right behind the battery:

 

 

It was easier to remove the battery and install the wire:

 

 

This crappy picture is showing where the power wire came out, it was well above the brake peddle:

 

 

Then I ran the wire under all the kick panels to the rear:

​I chose to ground the amp to this pre-existing "bolt" under the storage bin:

Next it was time to mount the sub in the trim panel, I created a template and cut it out:

 

 

It fit fairly well. However, I did use a gasket sealant maker to ensure it was nice and airtight:

 

 

I ran the speaker wire under the grey sound mating:

I had a better line out converter on order, but it's still in the mail. So I had to make a late night run to Walmart and pick up this thing:

 

 

A good mounting spot is between the passenger front and rear door. The only problem is that I was unable to tap into both rear speakers as the instructions suggest:

 

 

There was a perfect spot to ground the LOC and after tapping into the RR speaker I had to run the RCA and Remote Turn on wires:

 

 

Because this is a temporary LOC I only twisted the wires together and used electrical tape. It's ghetto but it works:

 

 

Because it was hard to find a constant 12v wire for the remote turn on, I had to run a wire from the main power at the amp and connect it to the yellow wire at the LOC. I then ran the remote turn on wire back to the amp. The reason I did it this way was because the LOC has something interal that turns on/off the remote turn on. Even with a 12v constant going to it. If I just jumped the remote turn on straight off the main power, the amp would never turn off!

Final product!

 

 

 

This whole project took me about a week to complete. Because I was not constantly working on it and because all the cure time I had to wait for the epoxy and fibreglass. It turned out good, it does rattle some areas but not so bad. Sub sounds good but could sound better.

 

I plan on building a custom wood enclosure to mount behind the trim and keep the sub in the existing location.

 

If you have any questions please let me know!

Just to clarify!

 

My Edge did not come with the factory sub woofer and hence did not come with an enclosure. What was in place was a small cubby hole about 10"x10". That is what I modified to create an enclosure.

How did you build the shelf for the amp?

 

Any close ups of the shelf?

 

Which line out converter did you go with and where did you ultimately place it?

 

Thanks in advance.
