Does anyone have any advice on what would be the best option for powered subs for the Edge? I am heavily considering the Infinity BassLink. (I'm also debating on going with something smaller and trying to put it under the passenger seat). I'm just not sure exactly where I will put it or how difficult it will be to install. I pretty much just want something that will give me some decent bass...not wake up the neighbors..but enough to vibrate my rear-view a bit. Also, I'm not sure if I should attempt to put it in myself. I was just going to add it to the existing system, so I know I'll need a converter, etc. I've not done any of that before and wonder if I should just shell out the $150 to Best Buy. Can anyone provide insight into how difficult it is to get the stock unit out of the dash, run the wire through the firewall, and conceal the wires going to the cargo area? OR, would I be better of throwing some Infinity Kappas in the doors and hooking up an amp to those? I'm just concerned that I won't get decent bass out of door speakers. Also, if I go with the powered sub, what additional materials will I need for the install? Basically, I just want something to add some bass to the weak factory system. Any info. anyone can provide will be greatly appreciated. Thanks, guys !!!
