Hey i'm 17 just got my car i'm on my l's and decided to do up my car before i got my p's. I own a 1995 ford futura and decided i need a good sound system. To start off intially i had 4 inch speakers in the dash 6 inch in the front doors and 6 inch behind the back seats. I got professionally installed a panasonic cq-c7300w deck a cadence amp and 2 12' pioneer subs. Well i didn't have enough money buying speakers so i left them. I happened to blow the back speakers. I went and bought some new better quality speakers i installed them myself as i have done it before but now they dont work. I can hear something out of the speakers not sure what but if i set the balance to only play the rear speakers and turn the volume to max i can only just start to here music coming from the speakers could anyone tell me what is wrong? or could help me? thanks
