Now, the ORION" Class-D Mono 1000 watt XTRPRO beign a class D is far more efficiant than a class A amplifier. However , with this being said ... I am in lack of knowledge about ORION.
Im concearned with # 1 . Sound Quality
In addtion #2. Reliability
With an Extra batter, I am in question, as to an additonal battery being wired.. Do I simply run the needed guage in parallel from battery under the hood to the batter in the back ?? with a 5 farad capacitor in the trunk to make things run smooth ?
Also , yes 147 Decibals ... Made it painfull in the car... You could breath.. but it was not comfortable inhaling . I never felt sound do such thing to the body , but made my ears ring , throat feel smaller, and breathing was far more difficult. Not to mention a punch in the back every time the bass hit.
lets not make this an arguement, because I know what I felt, and if you havent felt it.. then your experiance being inside a vehicle with such system is a personal lack you may want to discover.
