Okay, i have a predicament. here in two months, me and my drummer friend are going to enter a talent show, and all i have is an old ampeg b115. but i have two pa style cabs that are 8 ohms each. the amp itself has two 8ohm out puts. is there any way i can like chain the two pa speakers together (running one right now) so i can run them together at 8 ohms? i thought i remember someone showing a way to set up a cord so you could. Any help is appreciated! Thanks!
