of course theyre loud as fuck, thats why they are the best. i love loud systems. i think kicker even broke the worlds loudest sub record or somthin at SEMA.
anyway, yes they are loud, and no, they arent good for everyday listening, but they are loud!
good, quality, low frequency, no popping, subs would be JL still. the new ones are crazy good.
or if you want to spend some money, you can get some BOSE speakers.
