Most guys have a daily system. But it seams daily means different playing time for different people , playing two sounds at full tilt, to me isn't a daily system.
So I am asking, if you had to play your system for two hours non stop. How loud can you play without, your amp going into protect,or your sub getting stinky, or your car catching on fire
. Be it 135 db or 148 db . You can estimate your loudest db's by ear, no need to get serious. what is your best by ear.
