But driving through town voltage may drop into 12.5 at the lowest only depending on how fast I'm driving.So I know the jl isn't a super efficient amp, don't really want to spend a bunch of money on new amp even though I'd like to put more power to the sub.So I was thinking either get new amp that is more efficient or get a yellow top battery if it will help with keeping voltage more steady.I did add another 8 guage wire from alt to battery and grounded neg battery post to engine bay.Any helpful input is always good, thanks</blockquote>
