has anyone seen or have one of these if so what are the demsions of the box because I like the Idea i just want to build it with a 8 inch subwoofer and 2 6x9 vertical insead of horizonal. thanks

 

i'm interested in any replies here as well....what year are you looking at? i have a '74 coupe and, though sound won't be an issue for a long time, i'll be wanting to make my own box as well.

 

75 coupe

 

I actually have one in the back of my car, but I won't be able to pull any dimensions for a while. My car is back in central Michigan, and I'm in Pittsburgh, PA

 

When you get back to your car it would be greatly appricated if you could get the deminsion. I am a long time away from installing my stereo. Thanks

 

k, I'll keep you in mind, cause I too would like to add one or two small woofers

 

that is greatly appriciated

 

They suck, they suck, they SUCK!!

I got one of those and thought they would fit in the back in a way that it would not block the T-tops. Well, that was $150ish wasted. I made larger corner boxes instead and tossed that P.O.S. "Custom Fit" conglomeration of presswood and carpet.

 

Do you have the demensions I am not wanting to buy the one from ecklers I just want the demensions so I can make my own out of either fiberglass or mfd speaker board.

 

hmmm..... corner boxes you say? i was just looking at a few designs on corvettefaq.com, but they seemed generally to be for fastbacks. i'm gonna go at it with some cardboard this weekend and see what flies as far as corner boxes in the coupes. i want something original and different. we'll see, eh? good luck to us all

 

You would be better off not using those dimensions is what I should have said. It doesn't fit worth a damn and just sits on the floor. A simple box could give the same effect as their "custom fit" box did.

sorry, no dimensions. Just a warning that the box is not all it's supposed to be. You would be better off making your own that copying that thing.

 

I built one for my 80 with two 6x9s. My electronics buddy said the box was too big for just 6x9s but I did not want a big woofer. Turns out we both were right. I get plenty of base for my taste. I kept it simple using 1"x12" press board. In other words it is 42"Lx12"wx12'h. This size still allows me access to the storage compartments. I would never build one of these based on someone else's measurements. I later cut the "ears/corners" off of the front so I could remove the box when I wanted to without removing the trim pieces. Just leave the carpet extending past the box and it will fill the corners nicely. Total cost if I remember right was about $50.

 

I just finished building boxes for my 77. I used 3/4" plywood to put two 10" subwoofers and a 375 watt amp in the back. I did it differently than the one shown because that setup doesn't leave any room in the floor for tops. I used a width of 41" to allow for carpet. This sets on top of the humps and everything else is above that. 6X9s would easily fit and probably could sit even higher. My setup leaves about 31/2" to the bottom of the rear compartment. 6X9's could probably sit on the second hump using a width of about 48". That would leaves lots of room underneath.

I've been building speaker boxes for cars for a while, now...

While mid and high frequencies speakers aren't too finicky about the size or shape of their enclosure and mounting, the mid-bass and bass woofers are VERY finicky.

Each speaker design has its own unique set of characteristics, know as Thiele-Small Specifications. Six parameters that, when computed out, will give you an "ideal" box size in cubic inches for that particular speaker. Want more "boom," like the kids who listen to rap? Then the box should be smaller. Want a flat response curve (it sounds the same in volume from ~20Hz to 100Hz), then either a vented large box, or what's called an "isobaric push-pull."

There is FAR more to having a nice speaker set-up then simply going to Wally-world and buying a couple of cheapies...

Why would I say such things, you ask??? Because I got tired of speaker salesmen trying to blow smoke up my behind, about how this will work perfect with that, etc... And he didn't know what kind of music I even LISTEN to!!! (it makes a big difference, believe me)

IF you're looking for a speaker that will sound pretty good with a variety of music types, I'd recommend JL Audio. They have some nice-quality speakers, priced very competitively... And the key for them is that they work VERY well in small speaker boxes (~1 cubic for per 8" mini-woofer, and I've seen them require ~1.8 cubic feet per 10" sub, and two of them were hitting VERY hard, in a Geo Storm).

If you want that "boomy" bass that is with dance/hip-hop stuff, than use a vented enclosure. If you want more rapid response- like listening to rock, metal, etc... then go with a sealed enclosure...

I wrote a program on Excel to calculate the numbers, but I'll have to rewrite it again, as my old computer died and took the program with it... But I will rewrite it soon, as I'll be doing the same to my '74 Coupe, and also building some custom speaker systems for a couple of local bands...

Sorry to be long-winded, but I guess the bottom line is simple: there is NO box that is "universal" for a decent-sounding stereo... I would shy away from the box that's advertised.

 

JL 8w1 subwoofer, great space saver, great bass!

 

breathial, I would like to see what you have in mind for your car- whenever you get around to working at it. pics or drawings

 

Here is what I am doing with speakers in the back end. I am not that interested in a high dollar system so I went basic. This keeps the backend open for T-tops and luggage.

I've got a JL 10" sub that has been in my last car. I agree that JL is good stuff. Also look at MB Quart speakers. The JL 10W3 won't get in the 'Vette because the motor makes the music I want to hear there!

 

I bought a speaker box at a parts store. This allowed the installation of two 6.5 speakers and a mid range. Instead of putting in on the floor of the rear compartment, I built a shelf that layed across the humps in the rear. The speaker box sits on this wooden brace, and allows for room underneath to use for t-top storage.

I know the sound may not be the best with this type of box, but it serves the purpose in the short run while I spend my money on other interior pieces.
