Default 2006 IS250 Audio Build Log

This is my second thread on CL, the first one also audio related in the GS 2nd gen subforum.

This will be a slow build thread, as I'm still trying to learn more of the ins and outs of this car and trying to gather equipment for it.

It will most likely be a simple setup using stock locations.

The car for now:

Stock battery crapped out, so I picked up a duralast gold from autozone.



check out that stock SQ techflex to the right.

I thought I had the amps I needed, BUT 2/3 were duds

I was hoping to bridge a 4 chan to the mids, small two chan for tweets, and bridge a two chan for the sub.


The left two are duds. One powers on, but no sound. One shows no sign of life.

The trunk is where I worked on first. Since I didn't have all the equipment yet, I figured I work on an area which wouldn't require me to disconnect and cause to be without sound.


My first fiberglass trunk enclosure. Before this, I've only done kickpods and a-pillars.

Some supplies:


Harbor freight brushes:


bubble buster rollers: I only used the flat one on the right. The radius roller's grooves seems to be too deep and caused more problems for me. Maybe I'm using it incorrectly.

Prep


I got ahead of myself and didn't fully think things through. I got greedy and tried to get all the airspace I could in that little corner. I tape off and glassed an area which gave me problems when trying to remove the mold (circled in red).



Circled in Yellow is an area that will give me a little more work. That part is the hook for the cargo net, which I would like to keep.

Butter flavored Spray to serve as a release agent, so the mold can be pull out from taped area:



After 2-3 layers of glass cured, I tried to pull out the mold, but couldn't because of the red circled area in above post.

My solution:

Getting lost in the zone, I forgot how many layers were applied. I did try to keep it even throughout the piece.



As shown in the pics, I added pieces of 3/4 mdf to flat areas to help stiffen up those areas.

The following pics are where I am as of yesterday. I added more MDF where I could and more layers of glass. I then trimmed the edges so it can be ready to be wrapped. The wrapping will come after I figure out what to do for the baffle/port.

It is currently strong enough to where I can stand on it w/ no problems. I'm only 165lbs, though.



The port will be 3" diameter ABS pipes with elbows to accommodate for the required length need for tuning the enclosure.

I'm aiming for .85cuft tuned 30-32hz. Before trimming, the mold was able to easily fit 5 gallons which equates to .668 cuft. I will need about 7 gallons to net .9 cuft to accommodate for port and sub displacement. Subwoofer will be a Dayton HO 10". 10" to save space, and ported for low freq extension.

Subscribed! Can't wait to see the final results. I'm still waiting for someone to put a 13w7 in their 2IS trunk.

Congrats on the fiberglass work. I tried making some molds back in the day when I was in to car audio. Needless to say, it didn't workout all that well. That was CIRCA 1990 iirc.

I picked up some Peerless HDS Nomex 6.5" for damn cheap, so I shall use them for this setup.

I did some measuring to make sure they'll fit. It'll be a tight fit.

A spare door panel was purchased for some experimentation (Thanks javyLSU). I really like how they designed the grill to be removable.

Before:


After:




If Toyota designed the window to be about 1" higher...



3" Mounting depth:

^ Very nice. A Shop replaced all my interior speakers with Focal. Are you going to be keeping the stock head unit, and if so are you going to be running a 4 channel amp?
