Coding non DSP to DSP system
Hello, I put a DSP amp, speakers, and sub woofer into a non DSP X5 and I was wondering if I need BMW service to re-code my X5? I see the DSP settings in my navigation screen and I can change the settings. They only problem I'm having are if I turn the volume loud on highs the speakers cut out.. I'm think its because I used the same power lead from the non DSP amp which was a smaller gauge wiring and I'm thinking the amp is pulling to much power and is cutting out.. Does anyone know how much BMW charges to do this re-coding? Any help please would be greatly appreciated.. Mark
