What tunning would be the best for 80's Metal. I.E. Metalica, G&R, AC/DC and the list goes on. This is for a (1) RL-p 12 Dual 4. From all the info I have been reading lately, it looks like 1-2cuft tunned @ ~28-32hz. What do you guys think? I dont think I can fit 2cuft maybe 1.5. I was thinking 1.5 @ 28HZ Should i scrap the vented Idea and go sealed? I like my Metal, but some times I just like to wang out 2. so I want the best of both worlds. I will have 600WRMS on it. Is this to much, not enough? Please help me sort through this confusion. Thanks
