I'm looking to install a stereo system in my 70 Convertible but am having a hard time locating where speakers can go. I would like to install 2 up front and 2 in back with a small sub. Any advice?
Thanks

If you are not too picky, you can grab a cheap set of convertible rear panels that someone has aready butchered up with speaker holes and go to town on them. They come up for sale every now and then, some people give them away.

If you are really energetic you can use your factory panels for a fibreglass mold and create your own custom panel.

Same principle applies to door panels or kick panels.

As for a sub, pretty much anything will work in the trunk. You could throw the spare tire out and use it's hold-down to keep the sub in place.

A suggestion for the head unit to keep it stock appearing, contact a positive contributor to this board and all around good guy, "BigMoneyLewis" on here to set you up with something:

That's a great site "BigMoneyLewis" .
I'm thinking of hiding the head unit in glove box or behind the original radio. Not looking to cut any panels if at all possible.
How about making a box in the trunk and attach 2 speakers and a sub.
Will the sound go throught the back seat?

You could try putting either a DVC (dual coil) or 2 x3.5" speakers in the original 4x10 centre dash location. My take on the feedback is the 2 3.5" are a better option, but I've actually seen very little feedback on this setup in an E-body. The space to the metal dash frame is very limited.
Could try one/two of those under-seat subs from Custom Autosound or similar http://www.classiccarstereos.com/product/Undercovers-Speakers/UNDERCOVER-1.html

Thanks for that.

I guess the bigest problem is where to put the rear speakers, any one with a vert have an idea?

The guy that built my system has the ones mentioned above that are underneath the front bucket seats.

I have the indoor outdoor speakers and sit them on the floor pointing up...great sound and bass...no cutting of door panels

I mounted the sub to the V shaped frame behind the back seat of my Cuda. I had room to spare. I had to bend the spare tire mounting rod in order to move the spare toward the rear about 3 inches to make room for it. I bolted two Alpine shallow mount 4 ohm, 4 inch speakers together and installed them in the dash with heavy duty velcro from Home Depot. I paired those with two more 4 ohm 5 1/4 inch shallow mount speakers in the kick panels. I don't think that you can mount regular voice coil speakers in the trunk and expect to hear them very well. I'm not sure where you can mount the rears in a convertible.
Here is a link to the sub:

Sub,amp,in the trunk. 2 speakers under the bucket seats and 2 in the kick panels.

Thanks guys
looks like installing speakers in kickpanel and under seats are the best option. Just need to find some good boxed speakers to mount under the seats.
