To Sub or Not To Sub
|You gotta get that bass|
Planning a Box
|start with cardboard|
Apparently, directing your sub towards the rear creates the greatest decibels, so I incorporated that into the plan, pointing the sub towards the open trunk. I had intended to have 6x9 speakers in that area, though. From some older posts, you've probably seen the horizontal openings I left in that wall when I patched the PO hack-up. I wasn't able to duplicate that pattern while fitting a box because of the location of the gas tank vent lines. So, I modified the plan to include 6x9's mounted vertically to the front of the box. To allow for the sound to make it into the cabin effectively, I'll need to cut more of that wall.
I tried various plans, each with cardboard, cutting and shaping to fit into the trunk, between the hinges and under the gas vapor pipes. With each concept, I would test fit into the trunk and test the operation of the trunk lid, and consider how I was going to address the trunk light. When you think you have it, double check every measurement, and confirm the cardboard box sets as you envisioned. Then, buy a couple sheets of 2' x 4' 3/4" MDF, a bottle of carpenters glue, and some wood-screws that have at least an inch of thread and about an inch of no-thread closest to the head. The no-thread allows the screw to pull the sheets together while being tightened.

I stopped work on the box at this point so I could get a version one of a stereo installed. This also provided me time to pull together money for an amplifier and a sub-woofer. When I get back to it, I'll document it here.

I wired both the always-on and switched power for the the stereo into an always-hot circuit, and set the stereo to auto-off 30 seconds after I remove the face. It's a convertible; I won't be leaving the face on it when I leave, but I don't want to drain the battery by leaving the ignition switched to run when I want to sit and listen to music somewhere. I can operate a power button regardless. I installed the 6x9's into the horizonal holes in the trunk wall, but ran wire long enough for me to plan an amp. I reused the existing front speakers, knowing that my 6-1/2" rounds will probably go into custom enclosures in the footwells... in a not-too-distant future version. This initial version was to get sounds into the convertible, while spending the least. With the stereo wired, speakers wired, antennae wired, it was ready to go, so I popped the positive cable back onto the battery and fired up the radio. Soundgarden always sounds good, but when playing through a new system, as the first song through that system, "Spoon Man" was just that much better.
That's it for today. I expect to get back to the speaker-box eventually. I think I'll be mounting the 6-1/2 inch speakers before that. I'm discovering that the driver door speaker was fried when I bought the car; now, I can hear it farting. Yuck, and... fade-to-rear. As always, thanks for following along-
