Thanks, didn't even know it existed! This one is my go-to forum. I just posted in Car Audio. That AutoTuba looks like a beast!
it's the total opposite of a beast. An Alpine Type R 12 that can be had for as little as $99 in a sealed box with a 500 watt amp will have more output and take up less space. Even the 10 would be better. If you want a real small box look at the kicker L7 8 inch. The box can be as small as .33 CU. FT the 10 10 .66 CU. FT.
