What car subwoofer gives the best sound quality?
It depends a lot on the size of sub woofer your looking for and how much room you have to work with.Also the sub woofer enclosure has a lot to do with the way it sounds.Whether the enclosure is sealed or its ported and the size of the it will also make a difference in the way it sounds.I have to 2-12inch Volfenhag 1000watt German concepts that sound pretty good for the money.I also have 2-12inch 1000 watt zuez speakers that sound good for the money.Since you said that your not worried about money, im not sure if your trying to go all out but theres some 18inch kickers that will shake your nieghbors up. kicker,mtx,jbl,sonny explode,eclipse all make some good subs just do some research or visit a electronics store that deals with that,they are usually big help when they know what there talking about.
