Gumby, if you want to use the 4" Fostex, you can use that design that I posted awhile back, that uses the 4" PVC pipe as a T-Line. You can mount the "heads"( 90 degree "L" bends) right on your rear deck, with the speaker facing forwards, and use short sections of 4" pipe under the rear deck with bends connecting them to equal the 5 foot length you need, and bring the outlet of the port back up through the rear deck lid again. You could do this on both sides, and most of the pipe will be hidden under the deck. This T-Line is good down to the low 40's with the FE-103. SPL is limited, but sound is good. Also, price is cheap. No woodworking, and easy assembly. A small handful of pink insulation behind the driver is all the stuffing you need. Probably sound pretty good in a car, with the small area. Midrange peak can be tamed with a little "doping" of the paper cones. But, too much will cut the highs. Do one coat at a time, and listen each time. Cheap and easy,and should fit in your space requirements. Sounds like a plan. Why, because you're Gumby dammit! And a bendable plastic figure needs to have a bendable plastic speaker enclosure.
Question about Car speaker design.
I spend 4 hours a day in my car minimum. I don't buy new, since I wear the things out at the 45-60,000 mile per year rate. I find low mile older cars cheap and quickly rack up the miles. The latest "cream puff" for me is a 94 Cutlass Ciera, right from Grandma.
I have a nice Alpine in the dash with pretty green lights. A set of 3.5" Pyles and sep. tweeters bi-amped with a rather pricey crossover have made the front very listenable.
The 6X9's in the rear are not acceptable. Even after trying many different options. I find they provide "boom"...but to call what comes from them "bass" would be wrong.
I have 5 different sets of drivers lying around. The 4" Fostex I have been playing with and the 3,4 and 5" Stillwaters.
Since the Auto market seems to be dominated by the "neon-glow-blow-your-body-gaskets-SPL "competition" mentality, I have not found anything in two weeks of searching that can fit the bill.
There are a ton of sites with info on the 4" fostex for example. But none of these designs will fit in a car.
I am looking for something that I can fit into the rear deck of the Olds. Even PVC designs would be OK, cause I don't mind hacking the rear deck up...but it needs to fit in the less than 24" tall space that GM has allowed me to work with.
Anyone built thier own system for the rear deck of a car?
Any enclosure ideas?
Helpful sites?
