Can I use a 2-channel amp to run my front door speakers and my back deck speakers. Let me begin by telling you the amps power is 100 watts rms x 2 into 4ohms, 150 watts rms x 2 into 2 ohms. Now that is running at 14.4 volts if it runs at 12.6 volts it drops a little bit. But I don't know what my voltage is. Can I do this and will ir sound good. Now I realize that if I turn the amps power up all the speakers will increase. But I can adjust that with the fader of the radio right. Thanks for any input. Please get back with me as soon as you can so I can purchase it. Thanks

If you use a 2 channel amp, the fader will not work because you will only be sending a right and left signal to the amp. If you adjust the fade, all the speakers will increase or decrease. But you can run all 4 speakers off that amp, I don't think I would, but you can. Just make sure you do the lefts with the lefts and the rights with the rights.
