Ordered 12" Fiberglass enclosure from Visual Ice on eBay:

Very curious to see how strong a $180 fiberglass box is... I was able to stand on my custom boxes, so if this is as strong I'd be very impressed...
Will be installing an Image Dynamics IDQ12 D4 V4
Paired with a Rockford Fosgate R1200-1D Amplifier
Received my Plug-n-play low level RCA adapter from Technic PnP (HiFi (676)/HK (674) add-a-sub harness LOC
