There are several DSP amps that are the same model number. The key is to buy one that came out of an E53, the same year is best but all X5 E53 DSP amps should work. Some DSP amps from other model BMWs may work without reprogramming but that needs to be carefully verified. If the DSP amp is, for example, from an E70 or a 525 the speaker setup may be programmed differently in the amp. Therefore, to use a DSP amp that is not from an E53 it may be necessary to re-program the amp. The dealer can do it, or, in my case, the shop had the very expensive scanner that could get into the DSP amp setup.

Backup camera has been test wired for transmission in reverse. I still have to wire it so it can be used when vehicle is not in reverse. Currently my subwoofer (aftermarket) sounds great when I play music from my iPhone but is fuzzy when I use the radio. I need to run an RCA line for the Subwoofer to replace the current setup. That could be the problem or if the Seicane has separate equalizer settings changing those could be the solution. May simply be an adjustment to the equalizer or the subwoofer gain. With the IBUS with the DSP add on I have two ways to adjust sound, from the DSP screen or using the Seicane offering. They don't work together. Probably won't work on it until tomorrow.
