Does anybody have a good reference to building your own speaker enclosures for behind the seats in the luggage area of my 74?   I am mainly interested in Bass, but any info would help.  Maybe a 8  inch or 10 inch subwoofer.  Maybe with just one speaker?  Also what is a good brand of subwoofer that has plenty of punch?  Something I can get from Crutchfields?  Any ideas or comments welcomed.....

I'm traveling this week, so I can't include pictures, but in my '74, I built a whole box that goes from the back edge of the storage compartments all the way to the back wall.  It also goes side to side.  It stands about five inches tall (fits in just below the convertible top).

As for subs and enclosers... What do you want? good clear bass? or load rattle your filling bass? If its good clean bass ya want... you should look into 2 MA audio 8s in a sealed encloser. MA isn't the highest price subs out there,But they sound great.you should be abble to get a new set for about 80 bucks.As for the encloser they call for .8 cubic ft of air space each.Now if ya want harder bass you can go with a ported VT(virtal technology) style box. To bad VT is out of business,But on a up note thier patents were released. Alot of shops are reproducing their boxes. they are a ported box design. They aren't as clear as a sealed box, But take alot less power.I still  would go with the MA audio subs for either encloser. Now as for amps. MA audio make a good amp and are very well priced.I've never used 1 personaly, But know alot of ppl that have. Audiobahn also makes a good amp. I've personaly use 2 MA audio 10s with a rockford fosgate 300.2 amp in a 05 mazda 3 with a VT style box. They hit so hard  the sunroof cracked.  Oh yeah the rockford retails for 230.00 roughly I got got mine new for 170.00. And you WILL need a high amp alternator or atleast a 1 farad stiffing capacitor or your light will dim badly. If you would like me to design a system for you i'll be glad to. I have a 74 myself so i can get the measurments. I don't know if your at woodworking or not, If you are i can just send ya the measurement for the box. Either kind you choose. You can PM me or email me if ya need more info.

Thanks for the input guys.  Actually I was curious whether anyone has utilized the wasted space behind the wheel wells for speakers?  I have been playing around with a pattern and can fit a 6x9.  My question is where can I find information on the volume of space in the enclosure to make the speaker max. eff.  Finding room for a 10" bass is another problem.

Corvette Enthusiast has an article on speakers this month for a C3.  They put some small ones in the door pillars and the heavy hardware in the back.

Don't know if this is what you are looking for, but they do a good job with the pix.

MA Audio is the brand.http://cgi.ebay.com/2-New-800-Watt-8-Inch-Subs-MA-Audio-HK80XC-Subwoofer-NR_W0QQitemZ110193000019QQihZ001QQcategoryZ18802QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
