Intro: Speakers for Bluetooth Car Audio
This is a continuation from the bluetooth configuration.
this tutorial will show how to make speaker housing for your speakers.
You will need a drill: 4 in hole saw, 2 in hole saw.
dremel tool: drill bit, sanding bit, grinding bit
I must warn you: this is kind of an advanced tutorial having experience with different projects as well as various tools.
Step 1: The Speaker Housing: Trimming
I used 4 2" pvc pipe caps for speaker dome covers.
PIC 1, 2: I marked all the caps with a line to guide my cut.
Vid 1, 2 shows me cutting off excess material on the line to ensure a straight cut.
Warning: The video shows my masterful technique done with precision as well as lack of safety. But I knew what I was doing.
PIC 3: I measured speaker depth, then measured the housing inside from the line to the lip-leaving a 1/8 in lip for the cover.
Step 2: Drilling and Shaving
Using a dremel drill bit
PIC 1: First I drilled holes into the pvc cap.
How many? What size?
Well, as much as needed to allow all the sound to escape. You can even cut cross members (e.g. cross hatch-tic tack toe) if you want to place screen over the face of the speaker.
PIC 1: I trimmed the caps at the rim to create a lip to place a ring that will lock the speaker in place.
Using a dremel sanding bit.
PIC 1: I trimmed the outer rim of the housing to create a lip to place the supporting ring.
PIC 2: I thinned out walls just a little to fit the 2" speaker.
note: I drilled a small hole for speaker wires to run out.
Step 3: Housing Complete
I basically ran speaker tests, to check for dbl levels.
I also took this time to check for speaker's fitting, back cover fitting and ring fitting.
explained how to make in the next step.
Step 4: Making the Face Ring and Gluing
I used a drill and one 4 in hole saw and one 2 in hole saw.
PIC 1: I cut the outer part of the ring first. Second, I cut the inner part of the ring. Because I used the same hole to guide the hole saw.
Note: I drilled the outer part of the ring until almost through then I stopped. Next, I drilled the inner part of the ring the same. I continued to cut through the outer part of the ring completely, then continued the same with the inner part of the ring. Trust me it will be easier to get the ring this way. Unless you can find rings at 2" your done.
Also, I drilled holes on each side of the ring that fit the screws I bought. (wood screws 3/4" long). I would have preferred counter sink L-wrench screws, but could not find any. I used locking clips similar to auto speaker clips.
PIC 2: I used my soldering iron (not the good one) to melt one plastic bracket on each side of the housing.
Note: you can also use crazy glue or gorilla glue to glue the ring to the housing.
Step 5: Cleaning and Painting
PIC 1: I cleaned up the speaker housing's visible areas and painted them black.
PIC 2: Its just a random picture, for some reason people like looking at a lot of pictures during tutorials.
I will end with this,
to mount these speakers I removed my Tahoe's ceiling in order to check for correct spacing for the speakers.
I then used this time to measure and cut holes in my ceiling to fit the speakers.
Finally, I poked holes through the speaker's ring holes and through the ceiling. placed the locking clips inside the ceiling and screwed in the speakers, ran the wires towards the front using a hanger and ran the wires down the right front panel to the bluetooth module in the dashboard.
End results: well, it is loud enough for all the way in the back, in the middle and the front. However, it doesn't sound as good as I thought it would.
