4 Channel Amp Install Issues.

I have been trying to install a 4 Channel amp in the back compartment of my jeep grand cherokee 2007. I ran all the wires back there and the amp fires up fine and works when I hook it up with lead wire when its outside the door. However, i would like to use the stock wiring in the jeep so i do not have to take the boots off the doors. So I ran back signal RCA's from my aftermarket radio (4 channels) and then I ran up speaker wire that I thought I could tap into the wiring harness after it is being powered by the amp. But I did that and nothing was working. I do not have the Boston Acoustics radio and or navigation so I do not have a factory Amp i need to bypass. I was wondering if it has something to do with the jeep having 6 speakers or something. I am really confused at the moment.

Did you unhook the wires from the output of the radio? or just tap them?

By 6 speakers do you mean 6 speakers or 4 speakers and 2 tweeters. there is probably a amp somewhere if there are 6 speakers.

the easiest way is to connect the wires right before the boot or just run new wire.

Yea I unhooked the wires from the radio and made sure they were just going into the speakers

Yes, by 6 speakers the jeep has 2 tweeters. I have no idea where the amp is.

There has to be another way to do it. Someone has to know where the amp/if there is an amp in the car.

do you have a boston acoustics stock system? you can tell by looking at front door speakers, there should be a badge on the grill stating Boston acoustics if so. Anyways taken from wkjeeps.com
stock amp is behind panel on drivers side in the cargo area
