I am hooking up a stereo that was previously in my 95 eclipse and I hooked it up today in a 2003 grand caravan,I ran all the wiring and got the box and the amps in there but when I turned it on there was no sound whatsoever coming from them.I am kinda unsure that I grounded it in the right spot but the power lights are comming on both amps.If it wasn't grounded good would the power lights still come on?The only other thing I can think of is that I wired it wrong at the head unit.Is there any other thing that I could be over looking?Thanks in advance
