Hello, I have an Opel Vectra b, bj97 and would like to have a system installed or installed. I have about 800€ available. Did you actually have to get something proper for 😉 Well, should I have it installed or do it myself? I already know how it works I thought I needed for the speakers in the doors (4 pieces, which I don’t know) is also a amplifier, and if so I can’t connect exactly that. Subwoofer, end stage and wiring should not be used. Which subwoofer would you recommend and with which end level? Does it like it cracks properly. :-p or should I rather save some more money? Real clueless (: Greetings, Pasi 🙂
