for an easy you can get an amp run wires to all the speaker and subs.

for the input take an old set of headphones cut the wires a good distance away from the plug. there will be 4 wires total, a positive and a negative for right and left. use these wires to hook up to the amp. you may need to switch the leads if you get the positive and negative mixed up.

then you can use any portable device to suplly your music and can keep the dash stock.

i've done it without the amp as a temporary stereo in my old truck. if you have anyquestions let me know.
