iDrive screen upgrades with RCA pre-outs?
I have the HK system and it's quite a disappointment in low response. I'm currently running an additional JL amp and sub through an LC2i running off the rear speaker output from the OEM amp. It helps, but since the rear output is filtered the freq response is not there that you would get if running off unfiltered RCA pre-outs. Tried running off the sub output, but thats even worse.
Are there any iDrive screen upgrades out there that have RCA outputs? Or has anyone found a solution to RCA outputs other than running an LC2i off the OEM amp? I did see BimmerTech has a amp upgrade for the base stereo that has RCA outs, but thats not available for the HK system. |

On the flip side, running off the rear speaker post-amp outputs, you'll again be limited in frequency response but more of mid-range freqs, which are good for kicks and punches, but you'll miss out on the low sub frequencies. You can do a little fine tuning to bring in marginally better freq response, but in the end you're still limited to the output of the factory amp, and since the HK system uses weird spec'd speakers, the amp output isnt ideal. What I'm trying to do is run the aftermarket amp off a pre-amp, unfiltered signal. Typically this is achieved on aftermarket head units by RCA pre-outs. |
