[QUOTE="hispls, post: 7683424, member: 614752"] TO get loud out of a trunk you must seal off the trunk (like a wall). Port on driver's side. A friend of mine gets 150 give or take a few tenths consistantly out of his Accord trunk. He always runs 5K and single 15". He has used AB and Atomic 5K and a large variety of drivers. In his build LV5 wasn't a great performer though it seems more promising with Nightshade softparts and a stiffer suspension.... Large port (15 to 18" port area per cubic foot net) I'd shoot for 4-5 cube. Read that WHOLE THREAD "SPL GAINS" on SMD. Flush mounting sub helps, but mounting will be challenging with a heavy woofer like that. Duct tape helps, flaring port (in and out) helps. You will need a meter to figure out your resonance and you will want to tune around that. I like using sono tube for a port since you can tune low and cut it back an inch at a time with a utility knife to tune higher and see where you stop gaining. FYI LV5 should burp 7K but thermally it won't handle 5K for more than a minute or so. [/QUOTE]
