Thanks everybody, Both TT are hooked up and running, no problems at all. And thank you for the link, great site. More than enough titles for me, I will give em a try.The macs are only rated at 50 w.p.c., but tested out at 68 and 72 respectively. When running horns, you better have the cleanest source you can find, or those horns will let you know it immediately. 50 w.p.c. of clean power is more than enough to make the votts come to life, and they get LOUDDDDD
