bass_stalker

the way i usually run the radio is with the bass boost off. bass set to -7 and treble set to 4 with volume 42. i think it is like a 165 amp battery. and it plays for like 30 minutes or so. i have seen other radios on you-tube that have amps in them that can play for a few hours. and yes before the amp i played the radio for like a week of riding before the battery went dead.oh lastly i'm not running the battery completely dead. it starts at about 12.4 volts then after 30 mins or so it drops down to 11. something volts and then radio and amp shuts off

ok i know you guys are probably getting a little annoyed with my ice chest radio questions but here is my question.i currently have a lawnmower battery powering a 300 watt amp and a dual media receiver and it'll play all the way up on 42 for about 30 mins. my question is if i buy a car battery would it play any longer. also can you suggest any ways for me to conserve power. i have a video of it posted on the main site and i will post a link to it
