6 pre outs, 7 channels, what's the limiting factor?

Here's the hypothetical situation I have with another vehicle at home. I can easily install one pair of speakers in the kick panels, another pair in the front doors, and one more pair of speakers on the rear deck, plus a subwoofer.

I'm curious as how this setup would be wired. If the HU only has 6 pre outs but 7 channels as described above, how/were would you plugin or splice into the RCA cables to get the signal from the HU to the speakers? In this scenario assume multiple amps.

Please excuse my simpleton mind, my only install has been with a 4 channel amp to 4 channels, pretty easy.

 

You can split the RCA with Y adapters for highs/mids/or low pass.

 

I dont think I have ever seen 6 preouts on a head unit???

 

run the kick panels and doors off the same channel.

 

That was quick.

 

The crossovers that you describe are they in addition to the crossovers provided with a component setup?

 

That seems to address the situation, however please let me know if I've gone off the deep end, replacing several crossovers which came with the component speakers at substantial cost with an all-in-one crossover seems counter intuitive. After reviewing several sites and reading about component speakers, manufacturers make a huge point as to the quality of not only the speakers but the crossovers provided with their setups. My understanding of crossovers are they filter out certain frequency ranges which are undesirable for the speaker (ie you don't want an 80hz signal going to a twetter). If this is the case how important is the quality of the manufacturers provided crossover? Is this all a marketing ploy or is there some substance to using the provided crossovers?

 

not uncommon.

2 for front speakers
2 for rear speakers
2 for subwoofers.

 

Then why would you sacrifice the superior quality of the speakers crossover by re-installing your Sony unit? Unless your Sony ES outshines the other crossovers.

4x4Taco stated you could use Y adapters, but with every additional connection isn't there the possibility of adding signal noise?

 

Let's take the discussion a step farther, the folks who build competition systems with more speakers than your local Best Buy, how do they manage all the sound? Aside from a wiring mess, there must be some central hub for all the speakers to eventually get back to the HU.
