You need to post this in the audio section. It's been awhile since I messed with the bose, one reason why your speakers sound lower is because the bose speakers are like 1 ohm, since pioneers are 4 ohm... well you know the rest. As long as you are getting sound through the speakers I don't know if there is much else you can do until you get a new head unit.

 

2 ohms actually . But yes your running the pioneer speakers at a lower impediance which since pioneers are such poorly made speakers they will probally distort and be very low. THe only other thing i could think of is that you have the positive and negative mixed up.

 

you need either the NISA4H adapter made by PAC (somethign like that model number) or the Scosche adapter from walmart, it says made for ford, its a line-in convertor, that defiantely works. remove your pioneers or supposedly theyll blow due to the difference impedance.
