Haven't done an extensive build log for my truck so I'll go ahead and make this one, which will be a step by step of everything I've ever done with the truck (as far as stereo's go). I'm currently 11 dB louder than I was with my first system, so this truck has come a long ways (and has had many broken panels), AND I've kept it ALL IN THE CAB.
The first system that was in the truck was a Fi Bl 12 D1 running on a Powerbass ASA1500.1 at 2 ohms (didn't have the electrical to back it at 0.5 ohms, and I also didn't believe the amp would do 0.5 ohms at the time). SQ was good, got decently loud for a first system by doing a 137.5 at 40 hz. Box was 2.3 cubes net with a 3" aero tuned to 32 hz. That was back when I thought I was supposed to follow manufacturing specs...
Once I had that box, I wanted to dabble in fiberglass a little, so I built a set of kick panels to hold some PG RsD6.5 components. Turned out great for my first fiberglass project and I still have them in my truck 7 years later.
After that, I wanted to try something a little different. So i ordered an IA Death Penalty 12 when they were having their sale (was $340 shipped). Of course, the DP wouldn't fit in the box I had so I went a little crazy and did a fiberglass box. The frame of the box was wood, and I stretched fleece over the whole front. This was the 2nd thing I ever made with fiberglass and I think it turned out pretty good. Box was 2.5 cubes net with a 6" aero tuned to 36 hz. Highest score I did was a 140.0 at 41 hz, and I actually took home 3rd at the 2009 dB Drag World Finals in Amateur Psychlone division with this setup!
After a while I was bored with this setup and wanted to get louder, so I went to a center console build. The DP ripped it's surround a few months after owning it, so I reconed it and sold it to buy a 2009 Fi Bl 12. At this point I bought a Stinger SP1700 for $50 (stereo shop had no idea what they had). This setup was good for a 141.6 at 42 hz. Sounded great on most music but didn't get very low.
Then I finally made the switch to something other than a single 12 setup. I ended up trading my Fi a couple of years later for a pair of BNIB DD 1510's. I built 2 boxes for the 10's. The first box I built only did a 139.9, but my second box did a 143.4 at 41 hz and a 141.2 at 24 hz! This was so far the best sounding setup I ever had. But that was about to change with my latest build.
Once I had the 10's I wanted some louder mids and highs. So I set out to build a set of fiberglass door pods for each door to house an 8" mid range driver and a bullet tweeter. These panels have about 8 hours total in built time. Came out amazing. The mids are PPI 8" pro drivers and the bullets are AQ.
And all of this has led me to what's in my truck now. I'm sure with these pictures you'll recognize that I am the one who tested the IAD prototypes. The first amp i had after the PB was a PA BB2400.1 which was a huge piece of crap. Clipped signal at all volumes. lots of power, but not very clean. Anyway, I actually fit a single 15" sub behind the seat of my truck, and it's still quite comfortable to sit in. Box ended up being 3.7 cubes net tuned to 39 hz. Highest number to date is a 148.0 on a Massive audio 3K. To handle the power and to be able to add a 3rd battery again later I built a distribution center out of 1/2" thick aluminum stock. The middle 3 bolts on each bar are drilled and tapped for 5/16" bolts which are the audio standard for ring terminals of any size.
Also, my current sub is a production model IAD Reign 15. Rated at 1kw rms and takes the Massive 3k like a champ.
If anyone is in or around OK, come by the MWSPL show in Guthrie on the 5th of May. I'll be there giving out demos to anyone who wants to hear the truck. Hope you enjoyed the build!
