Update!
Its been over two months now since i have had the RSDC 12" and i am EXTREMELY happy with it.
Im still pushing the sub with 500w rms of power (set by DMM) and it is very very strong. I dont think i would be able to handle 1200w like some people are giving. In the song Put on by jeezy and kanye there is a part where the bass hits at exactly 500w rms 2 min and 48 seconds in i believe. That bass hits so hard that i have to cover my ears or they feel like they are going to implode, not to mention my car feels like its about to fall apart when it hits the lows on that note.
I have since Did the BIG 3 upgrade and i have a stable 14.4 volts coming out of my battery, now the only problem i have is that my alternator is barely able to supply enough amps for it, its 130 amp and the sony amp takes 70amps alone, so if i have my lights on at night i have HEAVY dimming on full volume.
Anyway i thought i would just update you guys! This is a great quality sub and i would recommend it to everyone!
