Question -
i drive a 97 grand cherokke and i cant seem to get the subs to work i hooked up the amp and all the wires but no luck what should i do
Answer -
Jason,
Can you be more specific? Do you know that the amp powering the subs has power, but the subs aren't getting it? Or are the subs receiving power from the amp, but it seems like no signal is making its' way from the head unit to the amp? If you could tell more more about what you've done to test this out, I'd appreciate it.

       THE AMP IS GETTING POWER THE RED LITE IS ON.IVE TRIED OTHER SPEAKERS BUT STILL NO LUCK.I WAS HOPING I DIDNT HAVE TO TAKE THE DASH APART TO SOLVE THIS BUT I GUESS I NO CHOICE. THANKS FOR THE HELP  

Answer
Jason,
Sorry i wasn't able to help more. If it's getting power, just double check all the signal cables. More often than not, loose wires are the single biggest cause of the problems I come across. Don't rule out that you might have gotten a bad amp too, with a circuit board that has to be replaced.

Best Of Luck,
Alan
