Adjusted the time alignment automatically at first using the built in fuction of the headunit then fine tuned using a doppler effect sound by ear. It just needed a nudge to properly align the singer center and eye level on the dash.

I'm curious, why didn't you use the RCA-Front outputs to run your midranges and the RCA-Rear outputs to run your mid bass speakers?
I am using network mode. using the 3 outputs available.
High - Mid - Bass
the only change i made was split the mids to a High-Mid & Low-Mid
you will have different settings on the menu while on network mode too
If that's not an issue, do the tweets "keep up" when you twist the volume knob?
I thought of doing it your way but the idea of using high quality, external amps for most of the drivers, but then the less powerful, internal Pioneer amp for the tweets makes me wary.
Thanks for any input you can give!
yes, it does respond to the volume knob, you can adjust gains on the network menu.
on normal listening levels the headunit powered tweets can keep up, tweets do not really require that much power. but if you want more flexibility and power running it off its own amplifier would the best way to go.
i just had it run off the headunit power because of the lack of space and funds :)
Question: would it be possible to power everything with one amp? My car just has two front speakers, two front tweeters, and two rear speakers. I might add a subwoofer. If one amp is technically feasible, would it be still not be a good idea because it would defeat the benefit of the 80PRS's network mode? Or could I still use network mode with one amp?
Thanks!
Do you find any time alignment issues brought about from having the mids geographically separated, but only being able to time adjust them together?
Seems like having more speakera than can be controlled individually could make creating a perfect sound stage challenging.
if budget is an issue
2 x tweets = 80PRS powered
2 x midbass = amp powered
1 x powered sub
2x amp 4 channel
2x mid
2x tweeter
2x midbass
2x coax speaker
2x passive crossover 2 channel
1x subwoofer
What can i do with pioneer deh80prs for 3 way best result?
PRS-80 High RCA feeds 2x channels of #1 4-channel amp, then goes to Tweeters mounted in dash. (crossed over in the PRS-80 at 3.15KHz)
PRS-80 Mid RCA feeds 4x channels of #2 4-channel amp, then goes to Midranges mounted in dash and Mid-basses mounted in doors. (crossed over in the PRS-80 at 3.15KHz, then crossed in #2 amp at 300Hz-100Hz for the Mid-basses, and 300Hz-3.15KHz for the Midranges)
PRS-80 Sub RCA summed and then feeds 2x channels of #1 4-channel amp, then goes to single 12" Sub. (crossed over in the PRS-80 at 100Hz).
I have Focal 165 KRX3 and want to setup the tweets to the head unit as you have in your setup. How did you split the mids? Are you using the from RCA in your setup? Do you use the amps crossover to do both mids and mid lows? if so did you use a Y slitter to have 4 RCA out to the amp for the mid and mid\lows? or are you using some other kind of cross over. Thanks for any help. Great setup. :)
From Pioneer HU
Top (Rear) RCA - High HPF: to MB Quart amp for Tweeters
(HPF) Pass everything from 3.15KHz up to tweeters
Middle (Front) RCA - Mid HPF/LPF: to Polk amp for Midrange and Midbass drivers
(LPF) Pass everything from 3.15 kHz down to 80Hz
(HPF) Pass everything from 80 Hz up to 3.15KHz
Then use the Polk’s onboard crossover to do a 2-way crossover @ 300Hz with 300Hz to 3.15KHz going to midrange in dash and 80Hz to 300Hz going to mid bass in door
Bottom (SW) RCA - Low LPF: Direct to MB Quart amp for Subwoofer
(LPF) Pass everything from 80Hz down to Subwoofer
