I'm putting together a list for stereo equipment that includes Diamond Audio S600s, JL Audio Stealthbox and a Pheonix Gold Octane amp.

Does anyone know what the biggest Optima Yellow is that will fit the S2k? Or what alternatives for big powerful battery do we have in the s2k?

Thanks in advance.

 

Yellow top Optima batteries come only in one size. I have a Optima in my S2000. Fit's with little modification. You will need to get a new battery tie down.
