Have you noticed any considerable amount of battery drain?
I currently have two 10" Rockford subs and a 1000 watt amp, however Very hesitant on putting anything in since I do not know about battery degradation and/or worsening my mileage.
Not going to lie, don't have the time at the moment to read into all of this.
But have you installed an additional subwoofer yet?
I am wanting to myself but am concerned of the power drainage and if it will take from the main battery or not.
