Well, I had nothing to do this weekend so I started another car audio project.
The whole idea of this project was to create speaker holder that will produce better mid range frequencies. So here's a lil info on why I went with this design. To get the best mids out of a speaker, the speaker should be in free air environment (so no ported or sealed enclosure). The plastic that holds speakers in our cars is too enclosed and only let sound waves come out from the back at which point they hit metal door panel and reflect back to the speaker (when this happens the sound waves cancel each other out, and totally kill mids freq). What I tried to achieve with this project, is to create a better speaker holder. I used 3/4" MDF, made a pretty wide O-ring (which is better then plastic because its less likely to resonate), like you can see in the pics the holder has holes on sides (this was made on purpose, to let sound waves go side ways which will bring out more mid frequencies.) Well I guess this is it. Another good upgrade which will bring up ur mids is dynapad (made by dynamat) or use of egg shape foam (not a good idea in doors because of wet conditions). But both of these products will cancel out back waves from the speaker and bring up the mids. If anyone has questions about anything please ask!













If anyone is going to do the same things, here are a couple of tips:
1) Use 3/4" MDF
2) Use Good liquid nail glue (something that wont fall apart from too much vibration, so same glue as people use to build subwoofer boxes)
3) Measure everything twice, then cut. This goes especially with the first peace because it should fit like a glove (because this part actually attaches to the door)
4) Use 100% silicone to fill in all the holes between the door and the first peace, and dont forget to screw it in with 4 screws (that u will need to buy because stock once wont fit)
5) Use hard plastic to guard the top of the speaker from wather (that comes down the door when its raining).

EDIT: I just finished the passager side, and it sounds way better then it did before, cant wait until I put some dynapad on that thing.

I actually never thought about replacing that plastic speaker mount - that's a pretty good idea. I just might try this. Nice job.

thanks!
U should deff replace it, I got way better sound with MDF

OK so I finished the driver side speaker at 7am today and put both door pannels in. It just sounds fantastic, I though this upgrade wont give me that much mids . Whoever competes in SQ or just likes good sounds from their speakers, you should deff think of making this thing! Oh and dont forget to buy some dynamat to get rid of all noises from tha damn doors

PS: Cant wait for the next SQL show (July 16th). I'll try to get 1st place in amature. But first I need to finish up my tweet covers and do some extreme tuning with my PEQ and TimeAlighment
