Rockville 15 destroyer subwoofer & Rockville db16 8000 watt peak amplifier.

My first time installing powerful subwoofer because I always wanted one and the price for everything only cost me around $460 because I got a refund of $230 from a returned tablet. I feel justified because I've always wanted one and the world is ending in a few years and back then but this set up will cost over $2000 (I installed a weak one in the past but nothing like this competition style sub).
After playing it a while, my entire car rattles and my voltage is draining quick. I can't play it longer than 5 minutes UNLESS I lower the volume or buy powerful alternator which I can't because I'm driving a hybrid Prius.
