The Issue:
The Woofer in an 8 seater sits pretty snuggly when the third row is in place. But when it is folded, the box tugs at the wires every time you brake or go up or down a slope. I was fed up with all the unwanted bass that the speaker was making by hitting the walls and everything else around.
I thought of a really low tech solution to fix this problem. I'm not sure if it works on other cars, but this works just fine for the 8 seater Scropio.
The Solution:
You need 2 - 3 meters of Velcro and this costs about 25 Rs per meter. You usually get this at hardware shops. But if you are particular about black colored velcro, try shops that sell tailoring stuff. We need the hard part of the velcro and not the soft fibrous part. Most speakers have a fibre finish that can naturally act like the soft part of the velcro. I got this idea from Red Liner who has dome something like this for smaller speakers. But he stuck the hard part on to the base of his speakers and used the fibrous parts of his car to interlock with the velcro at the base of the speakers. I did something a little different. Here is how you do it.
1. Measure the base of the speaker and cut the velcro band to the same lengths.
2. Now that you have similar length bands, Stitch or staple these together to form a large patch. I did both.
3. Check the position at which you want the speaker to be placed and then loosen the plate you see as soon as you open the rear door. (Not sure what it is called, check the pictures.)
4. Don't remove the plate completely, you may not be able to assemble it back. We just need a small gap to insert one end of the velcro under the plate.
5. Make two holes on the Velcro patch so that it corresponds to the pitch of the screws holding the plate.
6. Now insert the velcro patch in the gap and screw the plate back on and place the speaker on top.
Result:
Rock solid Woofer that does not budge even if you can drive your car upside down..
