It would indeed be retarded...so hows 1 18XXX in a 11 cube @ 30 sound?
You can make a ported box sound just fine with the right equipment //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifor a friends house and try a 15 or an 18 in a good sealed box.my money sais you never use a ported box again.
which is why I'm going that route. when I ought the 2 10's I was driving a stealth and couln't fit much more. now I have an exteded cab and room to playOne xxx 18 would get louder than your current setup by a good bit, and sound alot better doing it.
