they are 15oo each im thinking about taking the backs off both speakers and hinging them togather to make it bigger and easier to work in, i gave eight of these bulbs i went all out just incase i broke ne, so if i do succeed in connecting 2 boxes i will run four in them, i just dont know about flowering them, i will pant the inside glossy white once i buy the spray paint? is that good to use??. thanks for the feed back
