Thanks bud, I actually think that I'll be fine with the 600/6... if its loud enough for a headache its loud enough for me.
I need just a little more than stock at max to be happy. The problem is stock at max is heavily distorted, so as long as its at least as loud as that but clearer... I think I'll be happy.
If you'd like to pay it forward with all the help you've received and help me out I'd appreciate any advice you can give... the setup I believe I've settled on is at the bottom of this thread if you have any further advice for me. Still have a few small questions (in red)
Thanks again for a quick reply/the info!
