Help Setting up Speaker/amp
Hello
My head unit is a pioneer Avic 5200
my Amp is a Precision power A600/4
rms power 320W min 2ohms unbridged 4ohms bridged
high pass and low pass crossovers are 30-4000hz
rms power at 4ohms is 50w x 4 channels
rms power at 2ohms is 80w x 4 channels
bridged rms is 150w x 2 channels

I have (4) 4x6 3way speakers 2 in the dash and 2 in the corners behind my head
They are Pioneer TS-A4676R 200w 30w RMS 35-40hz 4ohms

I have (2) 6x9 3way Speakers behind the seats in the bottom corners
They are Pioneer TS-A6966R 420w 60w RMS 28-36 HZ 4ohms

I have (2) 6.5" round door speakers
They are Pioneer TS-A1675R 320W 50W RMS 32-40hz 4ohms

I would Like to know how You would wire this combination.

I also have an old school 2 channel 200w amp I could use if need be but I would rather not if possible.

Thanks for your help as I have not done any car audio since High school and I am 55 yrs old

I forgot to mention I have a 1990 chevy silverado standard cab

Safest way to do it would be to use 2 channels of the amp to drive the 4 4 by 6 drivers, with the crossover set above 200Hz. And the other 2 channels for the pair of 6 by 9s with the crossover where you see fit.

You will lose ability to fade front to rear, but will be able to fade 4 by 6 to 6 by 9.

I alasohave the door speakers. So would you put the 4 4x6's on 2 of the channels and the 2 6x9's and the round 6.5 door speakers on the other 2 channels. Would you use series or parallel or a combination of the two?
Thanks for your reply

Also with there being 8 speakers should I introduce the other amp. I'm a bit of old school. I'm not into the lisence plate vibrating subs that the kids are into today. I like some volume and bass but not so much vibration
