I hope this forum is ok for me to post a question here. I am thinking of buying a 10" subwoofer and am looking for SQ. Can anyone suggest a Sundown Audio subwoofer I should buy. I have 2 E- series in a big ported box with 2 12's and and love them with spl, but want to do a SQ setup for a different vehicle. If possible I would like the single sub would be under $200. I also will want it to be sealed. I'm also not wanting to use more then 600 watts. I just want the sound to fill the vehicle. I don't need to be heard blocks away. Thanks for your time.
