[QUOTE="K Tuu, post: 8871478, member: 690978"] Hello! I have HK Logic7 sound system in my MB W211 T, and added Z623 Sub into trunk for more bass. [ATTACH type="full" alt="Subs diagram.PNG"]57013[/ATTACH] Aux cable connected to factory sub cable: [ATTACH alt="IMG-20230311-WA0006.jpg"]57019[/ATTACH] It plays very good, even the rear view mirror vibrates now :D Bypassed this: [ATTACH type="full" width="223px" alt="1709284460548.png"]57016[/ATTACH] With this: [ATTACH type="full" width="398px" alt="1709284403630.png"]57015[/ATTACH] I have two questions: 1) How i could make the sub play only bass, can hear lyrics also at the moment. Factory sub plays only bass, no higher notes. Logitech sub has Amp inside, maybe it affects it? 2) If i turn music volume down from head unit, Z623 volume stays the same, factory sub's volume goes down (HK sub box is empty inside. Nothing between below sub and Aux cable). Dual voice coil subwoofer: [ATTACH type="full" width="276px" alt="IMG_20240229_174842_1.jpg"]57017[/ATTACH][ATTACH type="full" width="384px"]57029[/ATTACH] Should i add Hi-Low converter between original cable and sub's RCA connectors?: [ATTACH type="full" alt="Z623 High-Low converter.PNG"]57028[/ATTACH] [/QUOTE]
