Hey guys so I have three 1200 watt 12's hooked up to a 3500 watt amp. They have always hit really hard. Well I just sold my Cadillac and got a kia optima. So I hook everything up in the kia and for some reason it's not hitting nearly as hard. The bass used to make some shake well in the car with the music up nd now it don't even tickle ur nose. Any ideas what it could be?
