hey guys, i have been playing for about 2 years now and i just got a GK 700rb. usually when i jam with it i just use 2 8ohm 15's, but i like more highs. those speakers are my dad's and i need to get my own. i want to get a nice 4x10 to use just at 8 ohms when i just wanna jam. i was wondering if anyone has a GK head and what speakers go well with it and if its even ok to go full out at 8 ohms with the cab without overheating. well any information will help, thanks alot guys.
