Im doing a wall build in my roadmaster as we speak , kinda low power just basically a groundpounder. I'm doing 4 obsidian 15's off around 4-5 k haven't bought the amp yet. I'm looking to keep up with the sub stage which should be around 148-150. I have a kicker 350.4 and a sound stream 560.2 to work with. I'm not looking for major sq either just a nice loud clean sound. As much as I'd love to buy a couple sets of cdt 3 ways I'm not looking to spend a huge amount on it. I do have fiberglassing experience and have door panels big and deep enough to drop 12's in I'm not sure I want to go that big though. It will all be ran active off my eclipse hu
