What is everyone running?

Horns could be absolutely the way to go in these cars. I more likely will be scrapping the factory dash and going for something entirely symmetrical --and of course removing that atrocious hump over the speedo/tach-- so I may not have to go that route. I used kicks and large midbasses in my previous car with good results, needed to scrap said dead pedal.

Correct, Etons are the better Diamonds.

Horns, pros: incredible dynamics, efficiency (needn't much power), airiness, sense of envelopment in the music, great imaging out of the box. I have hear some terffic horn cars, Mark Eldridge's 4 Runner being at the top of the list, but those are hardly off-the-shelf parts.
Pat Gates' Explorer used Illusion horns, and with the talents of my friend Chad Peterson came out wonderfully. There are many others...

Cons: take a whole lot of fanagling (but so does anything else I guess), can be a little too aggressive/metallic/nasal if done improperly, often need to be supplemented with too many extraneous drivers to complete the sonic spectrum. A horn/midbass/perhaps tweeter is a nice array, but when you need to add midranges and such, you're up to a 4 way system, and can render the horns superfluous.

Can't fit my stereo in my sig..... its an old one, puy it in wayyy back in 1995, but its still in top notch shape, check it out;
