Alpine MRV F450 70x4@4ohms 100x4@2ohms.
2x Jensen 6.5" 40RMS 4ohms 125 peak.
Sony xplod 300RMS 10" 4ohm SVC Sub.
DUAL XHD 7714 Head unit.

What is the best way to wire this all up?
Should I do speaker level inputs or use RCA cables?

I want to take channels 3+4 on the amp and wire them to work with the sub. I don't know if that's possible. Maybe it can only be done with one channel.

The first two channels I want going to the 6.5" speakers.
I know the sub won't hit hard at all with 70RMS. I just want to add a little bass to the music.

Thanks guys.

You can bridge the sub on channels 3/4. The amp will provide 200 watts to the sub.

I would use RCA cables.
