if i was to put a two channel amp on my front speakers, where would i put the amp?

if i get new speakers, such as an alpine component set, should i run new wire?

would i put it in the trunk and run RCA's all the way to the trunk and front speaker wires all the way to the trunk?

or under the passenger seat and run RCA's to this and the speaker wires out?

if anyone has any pics or anything i would like to see.

 

I am using a 4 channel amp to run the speakers in my doors and it is located beneath the front passenger seat. I also ran new speaker wire into the doors. It was an easy job for me but I did get it done.
