i WAS putting subs in my 99 a4b5...but something ****ed up bad...alrite so now heres the situation...all i did under the hood was disconnect the battery and run the power wire for the amp, heres the problem, my car wont go past 1600 rpms...wtf?? just to be clear i disconnected the (-) battery terminal and now i cant get out of first gear?? what the **** do i tell my parents?? and even more what the **** is wrong with my car?? im totally baffled and would love to be entertained by any ****ing ideas

 

hahahaha thats really funny... I did my own install on my audi i got a alpine with a hifonics powering it just under 1200.. no probs at all.. but then again I knew what I was doing...your car is probably in limp mode... that would be my guess. are you automatic?

 

you connected through a permanent live so the amp is live all the time ( battery killer ) remove that wire and connect to a switched live ( live when the ignition is on only ) your amp is taking all the power, you also might need to upgrade the alternator depending on what amp you have in there

 

yea automatic :/ how do i get out of limp mode then? and i would love to have my amp connected to a switched live however no matter how much i searched i couldnt find out exactly where to find it without taking out my h/u. i tried using the preamp in the trunk and found power, but not my remote power. also, i tried using a loc but cant figure out what my speaker outputs are

 

remove the negative wire to the battery turn on all aux systems and leave for approx 20 mins and before connecting the battery ground switch every thing off ( obviously ) this should clear the ECU of codes, if it doesn't then it needs VAG to reset it

 

meaning disconnect (-) and turn radio on for 20 mins?

 

avant can u tell me which wires/colors are what on the wiring harness for the preamp in my trunk?

 

radio/ main head lights/ rear window defog anything, that's to remove any back up system from memory

 

can someone give me a map to where my amp is in my trunk??? on the left right next to where my tool box goes right??? And to answer you question if you remove the ground from you battery (-) then you cannot turn on anything hence your power source is gone... You want you amp to be connected live all the time... But you want to be able to turn it off when you turn off you car/ headunit... This is why we have remote turn wire that goes between the pwr and grd on an amp..

 

make sure the remote wire and battery wires are not touching. Did that in mine and had the same problem [:@] lol
