[QUOTE="RSDXzec, post: 8060278, member: 638347"] Just curious if anyone here has a way of telling approx what kind of db they're getting without a meter? I don't have one or know anyone that does and I don't have the cash to buy one. I found this a few days ago [URL="http://www.decibelcar.com/menugeneric/87.html"]Decibel Equivalent Table (whats how loud) | Decibel Car Audio the SPL Knowledgebase[/URL] which says at 132db eardrum vibration is notable so that tells me I've passed that and should be somewhere in the 30's imo. I'm only on 3 12"s ported at 400rms in a hatchback. Getting a new battery soon so I'll be pushing over 1k and I'd like some way of knowing approx what i'm spl hitting once i do so. From that table I'll know I've hit 140 once my throat starts vibrating. I havent heard a system louder than my own so I can't base it on experience either. Cheers. [/QUOTE]
