Hi, since I’m going to pick up a different car in January (Golf 4) I wanted to take a different end-stude! Now to my current system: -Sony MP30 Radio -Zealum 1F Powercab -Bluepoint GTA 4100 (currently 2 channel for rear and 2 for sub) -3 way cheap boxes on the hat rack, but the sale I do with the car! -Axton Cab 307 Since I don’t like the bass I assume it’s at the bluepoint final stage. Because I was told that the sub actually quite gu The GTA 4100 then wanted to use the standard boxes in the golf (later the other 2 way system will come in!) Wanted to do everything right this time so that I don’t have to buy new. What diameter should the cable have for the power supply (20mm)?? And the amps then I would like to connect to the Zealum Powercab, right? Hope you can give me some tips! What do you think of these amps: Axton C 408 Next Q-amplifier Q-22 HIFONICS Nemesis NX40 0 I wanted to spend around 150 euros, can be used calmly. As long as I get good sound in the car!!! Ray
