i have a 2006 mazda 6 4cyl. ive taken measurements and i kno an xs d1200 wil fit and so will a stinger spp1200. but i think i could possibly get a xs d3400 or stinger spp1500d to fit. i looked @ the kinetiks but they all measure too tall. i want the biggest battery possible. does n e have experience with this situation? btw ill be running 2k-3k wrms.
