Hello together, my car is a TT 8J Coupé with Concert Radio and the “Active System”, i.e. the power amplifier sits in the trunk and supplies all the LS in the car. Since depth/volume is missing, I have replaced the front two TMT and HT with Eton 172.2. The sound is much more detailed and beautiful, than with the original LS, but still lacks the depth so performance. I want to keep my Concert Radio and have the following idea: In the trunk I put another 4-channel En dstage (if necessary one wants a subwoofer in the future, therefore no 2-channel). This amplifier has a high-level input, so I plan to tap the NF lines from the radio of the front two loudspeakers, which lead to the serial amplifier, and lead to the new amplifier. I also tap the remote signal from the serial amplifier at the supply line. Mass and duration plus is clear, battery and mass point are also in the trunk. I walk away from the new amplifier with speaker cables dan n again to the cables of the two front loudspeakers, which depart from the serial amplifier. I would cut them so that they will of course only be supplied by the new amplifier. The original rest would remain like this, i.e. the rear LS and the Center-LS would continue to be operated by the serial amplifier. The Can-Bus also stays on and thus does not report any error. Here the occupation of the serial amplifier, which I researched with my note to the relevant Can someone please confirm that this will work so well? I thank you in advance. 1: Terminal 30 (+Ub) – ro/gn, 4.0mm2 2: Terminal 31 (GND) – br, 4.0mm2 3: LS front li (-) – br/ro, 1.0mm2 & – br, 0.5mm2 (this line I would interrupt and supply with the new amplifier) 4: LS front li (+) – ro, 1.0mm2 & – ro, 0.5mm2 (this line I would interrupt and supply with the new amplifier) 6: LS rear li (-) – br/gn, 1.0mm2 7: LS rear li (+) – ro/gn, 1.0mm2 11: CAN low – or/br, 0,35mm2 12: CAN high – or/li, 0,35mm2 14: DSP one (+Ub switched from radio) – gn/ge, 0,5mm2 control plus (here I would pick up remote, if necessary / no sense turn on at the counter) 15: LS front re (-) – br/gr, 1,0mm2 & – br, 0,5mm2 (this line I would interrupt and supply with the new amplifier) 16: LS front re (+) – ro/gr, 1,0mm2 & – ws, 0,5mm2 (this line I would interrupt and supply with the new amplifier) 18: LS rear re (-) – br/ws, 1,0mm2 19: LS rear re (-) – bl/ws, 1.0mm2 20: LS mitte (-) – br/gr, 0.5mm2 21: LS mitte (+) – ro/gr, 0.5mm2 24: NF rear li (-) – brown, 0.35mm2 Line 25: NF rear li (+) – green, 0.35mm2 Line 26: NF front li (-) – brown, 0.35mm2 Line (here I would pick up the signal for the high-level input of the new amplifier) 27: NF front li (+) – blue, 0.35mm2 Line (here I would pick up the signal for the high-level input of the new amplifier) 29: NF rear re (-) – brown, 0.35mm2 30: NF rear re (+) – red , 0.35mm2 31: NF front re (-) – brown, 0.35mm2 (here I would pick up the signal for the high-level input of the new amplifier) 32: NF front re (+) – yellow, 0.35mm2 (here I would pick up the signal for the high-level input of the new amplifier) Here is the planned new amplifier:https://www.ars24.com/verstacher/jbl/17015/jbl-stage-6004
