I bought this battery to function as my main power supply and it did not disappoint. I have it in a 08 c300 Mercedes powering a sundown audio SAZ1500D with a single Sundown ZV3 12. My original battery would make my dash and lights dim when the bass hit even while driving. I can leave my car off and still slam with absolutely no dimming with this D4800. I would definitely recommend and buy again! Not to mention the quality and look is really good, if only this bad boy wasn't hidden in my holod under a cover.
