rockford fosgate rfz3810 10 help

Assuming that's 400 watts RMS, and that it's a Stereo Amp, it will push 400 watts bridged into 1 channel at 4 ohms, anything below that wouldn't be safe. Wire your 2 8 ohm speakers in parallel and you will deliver a 4 ohm load to the amp. Seeing that the subs can only handle 300 watts RMS total, you will want to keep your bass gain fairly low, as the amp will deliver a little too much power.Jon

Don't like rockford subs? Then don't look at my car =)

If you wanted to be safe you could put one sub on each channel of your amp, except that would underpower those subs pretty bad. I think the setup that aggie altima suggested would be best. One thing though, the gain on the amp isn't a volume control, so the only way to keep those subs from blowing at high volumes is to just listen for distortion. I think these subs will be fine with this amp though.

I appreciate all you guys time it really bumps again thanks
