It was just for trials , urge to listen in car ...otherwise it was installed with my pc in my room this past week with a 240 amp battery .God it produced sick bass 
In car performs allaaa but I run out of power , still need to work out for that
Yeshh that's a proper way to install , but I need my back seat sometimes ....and uni starting next week ...car will be parked whole I'm there in hot sun ...so need a mobile solution ..
