[QUOTE="fireplace369, post: 8637179, member: 674783"] Hi. My sound system is currently a little above 1200W with one sub amp (this is accounting for amp inefficiency) and will eventually be about 1900W (One sub amp and one speaker amp; again accounting for inefficiency). I have a XStatic Model 400 batcap (rated up to 1300W) on my system now (which worked fine when my last amp was around 650W. My lights dimmed heavily with no batcap when I had that amp, hence why I got it), but now that I have twice the power, my lights are dimming very heavily again. The dimming occurs whenever the sub fires at all (short kick drum burst and long heavy bass notes). Although my alternator is fully functioning and rated at 130A, I have a small car with a smaller regular battery. I am stuck between buying a larger batcap from XStatic, specifically the Model 2000, which they say is 60% battery and 40% capacitor, or buying a deep cycle battery such as a OPTIMA yellow top or a XS Power D6500 to fix this problem and to be able to run my current and future system continuously for a good period of time (an hour or two) with no issues. In addition, I would like to know if a regular deep cycle battery works well powering an amp that just runs regular speakers (6.5", 6x9", etc.) or if everything would be better wiring a deep cycle battery for power storage and then wiring a batcap solely for the discharge together. (To my knowledge, it seems the way to go is wire my batcap to a deep cycle battery and wire only my sub amp to the batcap and run my amp for regular speakers directly to the deep cycle battery). Sorry for the lengthy post, any help at all is greatly appreciated. Thank you. [/QUOTE]
