thanx guys, i think im going to try that today.

When i bought my car the door speakers blown. so i went and bought some rockfords at best buy and they installed them (cause i dont know anything about stereo). they worked great for a while but a while ago they stopped working. Only the tweeters i got with them work now. The big ones dont make a sound. ive got the infinity sound system. one of my buddies told me a new head unit would fix it, but i think ill ask around before spending any money. any help would greatly be appreciated. thanx
