Ok so not long ago i got a stock mp3 head unit from a SSSC and installed it in the car. No big deal i had to go get it reprogrammed and all that...My question is why is it so quiet now? I put the old deck back in the car and its WAAAYYY louder than the mp3 player.

Is there anything that i can do about this cause its so quiet if you have windows down theres no chance you are gonna be able to listen to music. Its kinda annoying..I mean is it possible that they just need to reprogram it again or smoething like that?

 

no the reprogram is just changing the vin on the radio's computer... if you want more volume i would suggest adding a 4 channel amp

 

If you don't have the pioneer system and that deck is for the pioneer system then your using a non amplified deck with regular speakers. If its a pioneer deck then it doesn't have a built in amplifier, the amplifier is under the dash. If you do have a pioneer system then I have no clue...
