Amlifier not working (by 5 users)

what do i connect the remote turn on llead to, my old sub never had this function. and what will happen if i use a 10 or 8 guage wire on the amp instead of a 4 guage.

i hooked it up and it powers up ut no sound i have a good amp kit cause it works my rockford 1800 watt the protection light isnt on

The switch under the driver seat, near the brake and gas pedal broke as I was trying to turn more bass up. I went back to Future Shop to see if they can fix it, they told me they can't help me, and they have no switch replacement. They then lead me to this site and buy a new bass gain switch, I tried calling your number on this site for some help but it doesn't work, and says the number does not exist. 1-800-225-5689, if this is not the number please refer me to the right number so I can contact someone to help me. Thank you, sincerely, Michael
