Alright i have an old subwoofer and amp, probably 75w rms if that, and i'm really not wanting to spend much. 1998 2dr v6.

Am i better off taking wires from the front speakers or can i use the amp without too much hassle?

right now im just using a $30 scosche fm converter i got from walmart with an mp3 player so i really don't care too much about the quality.

Thanks.
