multiple front speakers

[Taman]

If you run speakers in parallel they would cut the impedance in half. In series, they add. For example. 4 ohm speakers would be 2 ohms in parallel. In series they would be 8 ohms. Most car amps can drive down to under 2 ohms of impedance. If you run a passive crossover the amp will not see that impedance. It will see the impedance of the crossover. With an active crossover, you would run separate amps for low, mid and high. Check to see how low of impedance your amp will drive. In series, the speakers won't be as loud, but you will be driving your amp at a very safe 8 ohms.

I thought one of them was a subwoofer and the other is a speaker.

In most cases when you see two 6 1/2" in each door, they are ran in parallel to single 2 channel amplifer at a 2-ohm stereo mode. If the amp is a 4-channel, same thing front channels in 2-ohm mode for the fronts and rear channels for the rears. In most car audio systems, rear speakers are designed for rear-fill only and is not the main focus for sound.

I'm pretty sure distortion rates increase on most amps with the lower impedence. Check the specs on the amp before you wire in parrallel.
