Featured How to maximize my new setup?

[Henry H.]

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?

I myself would wire to a final 2 ohm load on the subs. follow the wiring diagram as it shows. No short cuts on the wiring. id use a minium of 12 ga OFC wiring from the amplifier to the subs as well. Thats me though. I think youd be pleased at that ohm load and the amp will work fine, though may be lacking some power for my liking. Though, may be all you need. if you havent bought that amp yet. Id recommend a CT Sounds class d 1k giving a little head room to run a bit cooler and giving the RMS final power load without maxing the amp out.

Yes, I’d like to keep my current amp, wouldn’t a bigger amp run the subs too hard and blow them?

not if you set the gain correctly. heres how. theres test tones at the very bottom too...
