ok i have a completly stock system on my year 2000 mustang v6coupe and all i really want to do for now is hook up an existing pioneer 10" sub in my trunk and obviously add an amplifier but i do not want to change/modify my existing speakers/deck any suggestions?? thanks

edit: basically i want to take the strain of the bass off my speakers which are plenty loud but cannot handle much bass..
