The_quorum

I just got a 50w(RMS) x4 amp (4-8 ohms), 6.5 Rockford Fosgate 2-ways for all four main speakers, and a 10" dual voice coil sub.
I got the 4 main speakers and the amp installed just fine. Now what I'm trying to figure out how to hook up the sub to all of this. If I get a crossover, I'm assuming that I'd run the line from the head to the amp then into the crossover, then to the 6.5's out of the mid-range outputs, and the 10" from the low-output of the crossover. Does this affect the impendance (hooking up in essence 2 speakers to the same channel) (I'm not clear on this whole ohms thing), or do I not need to worry about this? Or am I completely off?
The head does not have a separate sub-woofer lead, and neither does the amp if that helps any.
What if I got a separate amp for the sub? how would I go about hooking that up then? HELP!

thanks for the info.

If your buying an active crossover (RCA PREAMPS) then no...

But I think you're trying to hook up the 10s with (another passive crossover)to the (passive)crossover box that came with your separates...

I think it may (not sure though.. any EE majors?!) It'll depend on the resistance of the subs too.

Have you thought of just getting a 3 way crossover since you're thinking of buying another set anyways? Make sure you keep the ohm rating same as separates...
