how to wire my amp to 4 speakers when stereo only has 2 RCA outputs????

[bkm48198]

My pioneer car stereo only has 2 RCA outputs and I have a 4 channel amp, I have the rear speakers running thru the amp via the RCA cables but don't know the best way to hook up the front speakers to the amp also. I assume I could run wires from the head unit speaker output back to the amp and then from the amp to the front speakers, or I could get a RCA splitter (1 female to 2 males). Can I use both the RCA's for the rear and also hook up the fronts thru wires to the high input or will that cause the stereo to have problems? I know I can't hook up the rears thru the wires at the same time as the RCA's but is it OK to hook up the fronts?

Y spliters.

What he said. Here's a link to a pair for sale so you can see what they look like.

If I use the y spliters won't I lose the fade from front to back ? I would prefer not to lose the ability to have more power from the rear at times and the rear speakers will handle more power than my door speakers.

Adjust the gains.

I didn't think of adjusting the gains. I've 54 and have never been into amps and don't have subs, just have a Mustang with a nice engine and want to be able to hear the radio better over the exhaust when I get on the freeway.
