Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
100db is nothing you will get that out of a $500 fusion package lol. You want sound go digital designs, go do your research watch a few YouTube vids or visit some shops.
My last system was Vibe audio which consisted of two 12s and bass 5 amp, focal utopias cost me close to $12000 and that got me 148db and 159db on a burp.
All comes down to your budget, you get what you pay for.
Yes. I want the sound to be really clear and perfect. But have a really really really loud system. I'm not sure where to go for my system to achieve atleast 100dB.
