Default Speaker wiring for 2 more speakers?

I want to add 2 more speakers. I already have the front door speakers and the rear sound bar. Now i know i had a thread about this before. But im still cornfused...

I have a second sound bar. I put it behind the front seats. So. Id like alittle explaining done for me. If i wire it up to run off the sound bar in the rear. Will the sound quality go down the latrine?

If i get an amp (found a 3 channel for $25 ) would i get a LOC for the front and the rear and just run the front sound bar (the 1 behind the front seats) to the head unit?

You can simply "daisy chain" the new sound bar to your current one. Sound quality won't suffer but your headunit will now see a 2 ohm load instead of a 4 ohm load, which will make it overwork/heat up/eventually die. Now, that amp should be able to handle a 2 ohm load so you could run all 4 speakers off the 2 channel section of the amp and have the third channel for a subwoofer.

I'd leave the fronts powered by the radio, as is....the loc will go to the rear speaker outputs of the radio and all four sound bar wires now go to the two channel section of the amp.

Head units kinda cruddy any way... So run the LOC to only do the rear? And if i daisy chain the 2 sound bars together then i can run that through the amp with 2 of the channels? Am i getting this right?

How to i daisy chain it? Im going to most likely have to upgrade the head unit eventually. But to be honest. Im not sure how to do that....

Take the two left soundbar speakers and connect the positive and negative terminals together via speaker wire. Do the same with the right two soundbar speakers. Now run two pairs of speaker wires, one for the left(front and rear), one for the right(front and rear). You can tie the loc in behind he radio or at the original soundbar, whichever is easier for you(this is wired to the original rear speaker wires, do not hook them back up to the speakers, to the loc only) The loc now gives you rca outputs to run the amp.

So instead of running in parallel what if I ran the speakers in series? That'd result in an 8ohm load, what'll be the results of that?

Ok so i should solder the wires together or what would be a good way to do it? And for the LOC both the sound bars would connected to it and then to the amp?

Spade terminal connectors will work just fine. The loc will only connect to the rear output of the radio, not the speaker's. The rcas from the loc go to the amp. The soundbar speaker wires only go to the amp, not the loc.

An 8 ohm load won't overwork the radio output but will result in degraded sound.

I'm no expert on sound systems.. don't even know what the LOC you mentioned is. I DO know that when adding speakers your goal is to match the impedence. If your original system is say, 8 ohms, the speakers will be wired in series or parallel to match the system. Two 8 ohm speakers in parallel = 4 ohms.. in series = 16 ohms. So it's the combination of all the speakers however connected to equal the impedence of the system.
*From your post it sounds (no pun) as if you want to piggyback the 'soundbars'? So, hooking them in parallel halves the impedence, in series doubles it. Either way will affect the resulting sound quality.
*Also, pay particular attention to the polarity of the speakers them selves.. if they're not correct they'll be out of phase, and that affects sound quality as well.
*Sorry for the 'not much help' reply, but my memory is swiss cheese.. I used to know this stuff.
