[QUOTE="cannabispinoy, post: 8264691, member: 661152"] hey guys i am new to forum and a car audio newbie. My current setup is 220 singer alternator, big 3 has been done(grounded well), crescendo amp bc2000d(bass), s800.4(mids and highs), 2 fi bl's in a ported enclosure tuned to 31hz. My question is do I need a 2nd battery in the rear? My lights dim a bit not too bad as before. If I got the 2nd battery would it help as I do have a SMD VM and i do see it drop from 14.9 to 13's when the bass hits.(sample song, Rack City) I have an xs power d2400 under the hood currently with all 0awg SHCA OFC wire. If I dont need a battery, how can I improve the voltage drop? I dont want to get a capacitor as i hear its a waste of money. Any feed back will help...FYI I did go on XS power's site and it says for a system around 3000 watts i should put a xs power xp750 as the secondary. [/QUOTE]
