[QUOTE="Henry H., post: 8879850, member: 691829"] I bought a ported sub box for my 07 f250 crew cab with .7 cuft airspace for each 12"sub (×2). Bought polyfill to make up for the recommended .8cuft for the subs. If I wire the subs together(+ to + ,- to -) and wire that to the amp will I be pushing 2 ohms at 500rms? Or should I wire it a different way?
