Cant seem to remember what my username and password was originally. Never received an email for my password recovery so I had to create a new one. Right now I am seeing if I can fit 4 of these under my rear seats of my 2008 GMC Sierra Crew Cab ported. If anyone has done this, has any advice, recommendations, or experience, please PM me ASAP. Once I figure out if I can do 4 of these ported at 30hz, then I will be ordering 4 of these. Funds are already available, just gotta see if I can fit them. Will be running these off of an Audiopipe 3000D So if all goes well, an order will be coming in for: 4 SA-8 V2 Dual 2 Ohm VC Subs
