E34 sound system

[Kamz e34]

My e34 had the stock speakers and head unit and they sounded bad. Few days ago i replaced them with sony speakers and sony head unit. Now it sounds much better. But the problem is that the front right speaker and the rear left the sound in them is so low. I have the base sound system euro spec i don't have an amplifier in the trunk. Does anyone know what it can be?

The European sound system seems to have a total of six speakers, four in front and two in back with no amp. Did you buy a harness to connect to the existing bmw plug and the other end with bare wires?

After a second look at RealOEM, it shows an amp in the trunk as part of the system, so you need to physically check the side covered areas in the trunk to verify if that is the case. As these amp have built in crossovers that might be paired with the original BMW radio head, and might not work with the Sony radio head, if that is the case you might need to rewire a passive crossover for the speaker configuration to get proper volume and sound.
