99 dakota club cab with infinity sound system. Amp previously bypassed when I replaced the back speakers.
so I don't have to worry about that.
I bought new speakers for the doors at the same time, finally getting around to putting them in. I got a set of component speakers for the doors, with separate Tweeters and a pair of individual crossovers
I had bypassed the amp with putting in the back speakers because of the ohm difference of the original infinity speakers.
So being as how the doors have wires within them already for the main speakers and for the Tweeters should I just hook the factory wires to the original speakers (and forget about the crossovers) or do I use the factory wires to the lower speakers and then wire the new Tweeters thru the included crossovers? I'm putting a different radio in, since I saved it from my wrangler when it went away/ but I'm not running subs or an auxiliary amp of any kind. The original speakers are just shot. Somehow the door speakers lasted a little longer than the back speakers. The PO of the truck for The previous 17 years was an 86 year old man when I got the truck from him, I'm sure that I have run the radio more often than what he did in the year and 1/2 that it has been my truck. But the backs were shot from the day I bought it.
i know that some people set them up weirdly. Like my mother in law, I didn't drive her car often but in her case every time she called me to work on that car the treble was all the way up, the bass was set negative, and the balance and fader were such that it only had any sound coming out of the left front. I'd spread the sound out among all 4 corners, add just a little bit of bass, (only like + 2 or 3,max was 10) and lower the treble so it blended in and it never failed, next time I got into that POS it was full treble, neg bass, and about the left front door again.
idk if the old man ever did anything but turn it off and on, but I wonder if the way he had the sound and balance set up had anything to do with the back speakers going bad so much before the door speakers. The backs were completely blown, the paper was completely separated from the rim, they looked more dry rotted than anything. To touch the foam around the edge would make it crumble and fall apart when I pulled those original back speakers.

 

Factory setup has no crossovers, per say. The tweeter has a capacitor on the back of it as I recall, mid-woofer doesn't have anything (I dont recall seeing an inductor on it). Two 6-ohm drivers make a 3-ohm load at the amp, while factory rears were 2 ohm, IIRC.

I would use the aftermarket crossover.

 

your talk about ohms and load is Greek (or may as well be) to me. but I understood that last line. I just didnt know if there were already crossovers in the truck that I didnt know of
