Four channel amp for six speakers

[Bikeboy80]

I figured out a few weeks ago that both factory rear door speakers were dead and ordered replacements for all four doors. I have since decided to upgrade the other speakers and add existing amps that I have for a modest system. I have a two channel amp that will run a new dvc sub in bridged mode. And I have a four channel amp to run the other door speakers plus the rear pillar speakers.

So here is my question, what would be the best way of wiring up the six speakers to the four channel amp? Should I run the door speakers as normal and just splice off of the rear channels to run back to the rear pillars, or should I hook up the amp in three way mode with the front four as normal and the two rear in bridged mode from the amp?

I hope I am making some sense....

What ohm are the speakers

The speakers are all 4, sub is 2

I would say hook up your rear door speakers and tweeters together on the same rear channels. The ohm load won't be correct prolly but it should be fine. Or just ditch the rear tweeters all together. I'm in the mist of doing a new system thru out my Denali and I'm ditching all the stock speakers and gonna run 2 sets of components. So I'll still have 4 speakers and 4 tweeters for a total of 8 speakers just like stock Bose system.

i would just run the front doors off the front channel and the others off the rear. Shouldnt hurt anything.

I've been trying to read up and educate myself on ohm loads... Should I be paying attention to wiring in series and parallel combination to end up the 4-8 ohm load the amp wants?

Let me clarify that...

Front doors, 6 1/2 3 ways plus add on pair of tweeters
Rear doors, 6 1/2 3 ways
Rear pillars, 5 1/4 components with tweeters

All are rated at 4 ohms.

I was kinda thinking of running front doors on the front channels, rear pillars on the rear channels and the rear doors on bridged mode. Would that work?

If you bridge the rear doors, you are cutting the impedence by half. Resulting in a 2 ohm load by bridging the two rear speakers.

If you wanna run that many speakers, your best solution would be to run two 4-channel amps. And save yourself the headache of figuring out the ohm loads and what not

So if I forget using the bridged mode...

Front door speakers run in series, two at 4 ohms would put me at 8 for each of the front channels.

Could I then run two of the rear speakers in series, then add the tweeter in parallel would look something like 4+4=8 then the tweeter would bring it back down to around 6?

Am I making any sense? Or am I making it to complicated? Just trying to use what I already have.

Haha just a lil complicated. Well on your front speakers each speaker is gonna get its own channel so you won't have a 8ohm load. You'll have a 4ohm load from each speaker on each channel 1 & 2 and then do what you were saying on your rear channels 3 & 4 and you should be good to go. In the rear you will want to hookup one speaker and one tweeter together on a channel and then the other speaker and tweeter on the other channel that way you still have left and right balance/fade.
