it's amazing how much air 4 18's can move if all 4 of them are moving the same direction. It's amazing how much air movement you lose when one amp probably never worked in the first place, so your port never functioned correctly and one sub was moving the inverse of the other three.
Much love to Audiopipe. I called Jackie what, a couple weeks ago and sent it in? I got a BRAND NEW amp today, even improved to run off 16V. Thanks Jackie.
So my setup is completely different now. I love it.
It's a good thing I turned my mids and tweets back up, they still cant keep up though.
Oh, and amazing sound quality is sort of killed by insane door flex.
