I've got an old Solobaric 15c, had it since '99, that I recently threw in my sons Scion xA just for the hell of it. It's been in a 1.5 ft^ sealed box since new but if I leave it in his car it's gonna need a new box built. My question...Is 1.5 ft^ optimal? 4th order maybe? There's about 4-5 ft^ in the cargo area available. It'll be getting 600 rms with a decent HU.
I also have a first gen L7 10. Would I be better off to ditch the 15 and go with the 10 in a ported box? I know these subs aren't the greatest but either one will be plenty good enough for his first bass experience.
Music interests are mostly metal but still like to throw in a bass track every now and then just for fun.
