My truck keeps on dimming lights badly, and now it is blowing fuses out of my amp. SO I figured it's time to get a new battery. I think I did the big 3. 4 gage wiring, new alternator, stock battery (I think that's where I went wrong). So I was wondering what battery should I get. I was thinking about getting a yellow top. I think there are a few different kinds yellow tops(like marine and car), but I really don't know if I should get a yellow top or is there one better out there? and also my amp is an MD2D which does 1800 watts (I didn't know if that would help).
