So it's okay to run XS power s975 as a secondary battery for car audio? I bought the s series instead of the D series because it came with brass terminals, but it seems that it's just a racing battery and not for audio. It's a 12 volt AGM. Please let me know if it's all right to use this as a secondary in the trunk or if I have to put it under the hood as a primary. Thank you for your time.
