Always been a fan of having loud bass so shortly after buying my Gold Rush in March I started researching how to install a system.



I saw some posts about the JBL Stealth box and also how to install amps in the wheel well. I thought the price was outrageous so I decided to do a DIY.

First, I upgraded the mids and highs so I could hear them over the bass. My RS5 came with the premium HU which I wanted to keep because of the steering wheel controls so I picked some speakers that matched the rating on my Sony Amp. I went with infinities both front and rear. And when I say rear, I ditched the rear door speakers and installed them in the c-pillars.

First I yanked out the interior so I could dynamat everything







Then I made a template for the c-pillar insets out of paper. I used this to cut out wood speaker surrounds.







Then I drilled a hole in the c-pillar pieces to pull the speaker wire through and glued them in using Liquid Nails







I also dynamated the doors and installed those speakers.



I ran all the wiring back to the spare tire area where I wanted the amps.

Next I made a rack for my amps and cap and then made a cover.



I also had to custom make the sub box. I followed this tutorial exactly:

Here's some shots.

















I'm really happy with the way it turned out. The bass sounds fantastic. No rattling at all. If you have any questions just post and I will respond.

 

I really like the speakers in the c-pillars.

 

do you have the measurements for the c-pillar templates???

 

I still have the templates but I'm not sure how you could recreate them from measurements. Each corner has a different radius of curvature. I had the cargo net c-pillar accessories installed so I took those out and traced them. I could take a picture of the templates with a ruler in the picture so you could print them one to one if you want.

 

this is true i didnt even think of that, hmm well i think the easy thing to do would be to order the c-pillar nets, then just send them back (i work in a toyota parts dept.)
but thanks for offering to take a pic for me!!!

 

That looks really nice. When I first saw my xB, I immediately knew speakers were going to eventually be in those c-pillars. Then I noticed everyone had the same mindset!

 

very sick subbox made. Looks so simliar to the JL stealthbox! awesomeeeee

 

The RS5 looks really good with those TRD wheels, nice install too!

 

Very clean install...

 

Good job with the custom install. two questions 10 are those 3 ways you have in the front? it looks like you have a wire running to the rear of the door panel in one of the pics. 2) I have a matching Rockford fosgate 4 channel amp if your interested. it was in my wifes car for 4 months before we traded in her car its been sitting with my collection since then. let me know if your interested. its the 600a4 I believe.

I started doing the c-pillars tonight its going to be a toughy for me. It looks sooo simple but its def somethin that takes time!!

@rj how long did it take you from start to finish for every thing, sub box and all??

 

I really worked on it in stages. I'd say it took me 3 months over the summer. The sub box took the longest. I had never fiberglassed before so it was a learning experience. The speakers in the front were originally 3 way but I changed them out down to 2 way components.
