Hey guys my e430 had the bose system in it the original owner took it out and installed a amplifier by connecting rca wires directly from the back of the radio.B4 selling the car he took the amp out and I bought a jl audio six channel amp wich works ok but I am not able to adjust the bass , treble or anything on that system. Now my first thougt was to purchase an alpine cd changer to go with it and keep the mercedes head unit then I was thinking why bother with the changer instead I can replace the mercedes hu with an aftermarket hu that can play mp3's convert my regular cds into mp3s would be just like having a changer .But my dilemma is how can I find a nice unit that would match the dashboard.

Any suggestions would be greatly appreciated and if you guys made similar upgrades let me know



thanks
