I was able to get aluminized reflecting fabric on ebay a few years ago which I have been using to get more sun light in my growing area. I also use roofing aluminum sheet stapled to waterproof plywood on the ground to reflect sunlight up. dcarch

I'll try to find out Benny. He bought the house 6-7 yrs ago & they came w/ it, in the walls. You got me going now on speakers. I have 2 other sets besides what's on the wall. I will hook up wiring to them & try them out & tell you which I think is best. I bet the smaller ones are the best. One set (on wall) is panasonic, 2 smaller (in size) are pioneer & the 5" x5" (half size of pioneer) is Clarion. The last two are both 3 way, 20 impedance & 60 watt and they sounded great in my old cars. You don't have to spend big bucks for good speakers these days. Will be busy tomorrow but you got me going on trying out these speakers & I'll let you know! I'll send you pics too if you want ( your email addy). Patty

South side of the house may be pretty hot in your location, but I am a NE coast grower so not well versed in your particular challenges. Maybe post this question to the regular tomato forum and ask southern growers what they think? This is the pest forum.
