so i just wired up my a4 with a 4 guage wiring kit. i used to have a honda and that was pretty basic to wire the system. so i assumed it would be the same. i finished wiring it and i turned on my cd/dvd player and the sub wasnt on. the amp power protection light was on but not the sub. am i supposed to do anything else besides everything from the amp to the headunit (besides the power/ground of course)??? please let me know if you know anything, im dying to get this thing working!!!!!!! THANKS

 

lol did you run a remote wire???? gotta have one of those to work man

 

haha for sure i did. i checked it to make sure it was plugged in and that wasnt it. just run that to headunit right?

 

yea that should be run to the headunit.... umm and everything is turned on on the deck for the subs?? nex check the settings on the amp. the LPF should be set at like 80hz and the gain should be turned up a bit

 

both done. im not sure what the problem is. someone told me i have to wire something to an internal amp somewhere? i wouldnt think so but anyone heard that?

 

i am assuming you have an aftermarket head unit... does it have any kinda on sub-amp on/off function in the menu alot of panasoni, poineers do and the default setting is usally turned off

 

but if your just adding a sub you shouldnt have to mess with the other amp.... what deck at your using

 

jenson pop out dvd player. i got it installed at tweeter for free so i dont think the connections at the headunit is the problem.....?

 

If the protection light is coming on you must have a wire crossed or pinched. What did you ground to? Try changing your remote to the head unit.

 

i grounded to a screw under the back seat. thats all i could find. the remote is already going to the headunit. would the ground make the power light go on but no sound????
