[QUOTE="hispls, post: 8836238, member: 614752"] That's probably too small by half for two of those square 12s. You definitely don't want to be mixing and matching different sub amps, particularly not if the subs will share airspace. Ideally you will have one amp that powers everything so that you won't have to worry about gain matching. If I'm not mistaken those L7s are only like a 750W sub so I'd think Taramps SMART 3K or similar 3K full bridge offering would be a good pick for an affordable amp that would power those up well without too much worry of breaking subs. The big issues I see here are that you probably do not have adequate electrical system to feed 3000W sub amp(s) and that you may not fully appreciate the sort of box you would want to come up with 15 cubic foot (or a bit more) net volume plus adequate port area. It will be big and heavy (or a proper wall built into the vehicle) and will require a good bit of lumber. How comfortable are you with woodworking? What's your budget here? Finally, if you plan to play music whatsoever, your goal is not "SPL". [/QUOTE]
