Which is better? (Component Wiring)

Greetings,

Im using a 4 channel add amp harness (with built in passive LOC 2 front + 2 rear) to patch in 2 tweeters and 2 front door 6.5 drivers driven by an aftermarket kicker 800.5, all crossovers by amp DSP.

For sake of best audio quality, lowest noise, and minimal disruption of wiring, which option is better?

1) LOC "front" higher output pair send to front doors and LOC "rear" lower output pair send to tweeters. All channels have attenuator trimpots but trying to keep SNR optimized. No rear speakers. I have read on here its roughly an 80%/20% ratio front/back signal power coming from stock head unit. 40F + 40F +10T +10T

2) Ignore lower output "rear" channel LOC pair and split signal of "front" pair into 4 channels to have equal gain sends going to all 4 channels then feeding amp and then +/- levels with the amp's DSP. No rear speakers. 20F + 20F + 20T +20T, 20R not used.

Essentially I am concerned the stock lower output rear channels will be noisey if amplified especially for tweeters. And not sure the rear channels are even discrete within stock Toyota head unit anyway..so it seems option 1 makes the most sense for the harness but option 2 assures equal levels going to amp, removes unknown signal molestation of rear channels, and also keeps the rear channels available for future rear upgrade.


thank you.

 

Use 2Ch input from your front out and steer everything with the DSP.

The only down side to this is your fader control on the stereo no longer has any effect. The pros outweigh the cons IMO.

 

ok great. i wont be using rear speakers anytime soon anyway.
