Hello together So finally I am closer to the sum I need for my last parts! My system concept looks like this: Headunit: CDX-MP30 <-- get cheap and am satisfied Amp Front maybe also Rear: Wallet 4/320 <--Do I need Amp Sub: Wallet 2/300 <--Do I need Front: Focal 165 (perhaps even the V2 variant) <--Do I need Rear: AIV Green Power (Koax) <-- Do I have Sub: from the PA range (2*30 basses in a 95 liter BR housing) <--- Do I have Powercap: Brax E-Cap with 1F <-Brau ich ich Kabel für das Konzept: Strom Wandet 4/320: 16mm2 Strom Wandet 2/300: 25mm2 Chinchkabel: 1*5m Oehlbach, 1*1m Oehlbach LS-Kabel für Sub: 1m 4mm2 Oehlbach LS-Kabel für Front: 2*5m 2,5mm2 Oehlbach LS-Kabel für Rear: 2*1m 2,5mm2 Oehlbach <--- Depends on whether they come to the amp! Residual tasks: door insulation: bitum and squirtbitum That's how I imagine it! Lack of amps, the front system, powercap, 16mm2 current, LS cable for front and door insulation! My music is rock (everything possible from Jimmy Eat World to Slipknot) and my car is a Corsa B!
