ok I bought a Jensen MP1516BT and it is pretty cool i like the look of it but installing it was/is a nightmare. the harness that came with the radio was completely wrong, the black wire that had ground written on it was actuality the 12v power and vise-versa. how could they ****ed this up. i broke about 7, 10amp fuses and scratching my head trying to figure out the problem. now that, that is sorted and everything is connected the unit turns on, but the front right speaker has very low volume. i don't know why i checked the wire and the connections the diagrams but nothing, i cant figure it out. also if i drive the right front speaker omits a high pitch nose that gets higher with RPM change so the higher the rpm the higher the noise (not louder but higher pitch). any idea please Help im desperate now man

 

what i also did was switch the right front cables with the left front, the problem didn't switch by right speaker steel had low volume. But what did happen was that if i wanted to have music only on the left front, or only the right front, i had to switch the balance on opposite sides, which makes sense since i switched the sides. with the oem radio head unit everything works fine no problem what so ever, and it sounds so much better compered to the aftermarket, maybe because of the problem that the aftermarket has. PLEASE any ideas would be very help full and very appreciated.

 

Did you check your speakers for damage? I would assume you did to connect the new radio, but if you just cut into the wires behind the original radio, then your didn't have to remove the speaker grills.
Mine were basically dust when I took the grills off the front. Backs were fine.

 

the speakers are fine because with the Stock OEM radio works fine. I talked to a crutchfield tech and the guy said that i have to buy Scosche SLC4 for the bose amp to work nicely with the head unit
