I have a set of Polk components that I will be moving into my Ridgeline. I plan to located the tweeters from the components in the stock location which is on the dash firing into the windshield. The 6-1/2 woofers will go in stock location in the doors.

I would like to bi-amp these, and I think the active xover and time delay from the 3sixty.2 would help with the tuning.

However, to biamp these using the 3sixty.2, I think I need to feed a single signal (Front L/R) from the aftermarket deck to the 3sixty.2, have it "sum" the signals, then conect the Front output of the 3sixty.2 to the amp channel for the tweeters and the rear output of the 3sixty.2 to the amp channel for the woofers, and set the xover on the 3sixty accordingly (BP for the woofers, HP for the tweeters).

Part 2 of the question: Assuming that will work, I have a second set of Polk 6-1/2 woofers that will go in the rear doors that I want to run as mid bass only. With the 3sixty.2 in play, is my only option to "y" the rear channel (used as the front woofer) to another external xover, or would the center channel be a viable option? Since I assume the center output is summed L&R (similar to the sub output), if I keep the HP side of the BP for the mid-bass woofers low enough, might that work?

One way gives me stereo mid-bass, but no ability to adjust time delay, and I'd have to set the xover manually. The other way would allow me time delay, 3sixty xover adjustment, but mono (L&R summed) signal.

So thats what i'd like to do, but what are everyone's thoughts on:

Component woofers as mid-bass drivers?

Mid-bass drivers in the rear doors?

Xover settings for mid bass drivers (60-200hz, 60-500hz?)

And finally mono(summed) signals for midbass drivers?

Thanks

just get a 4 channel amp and it will work fine!
