Hello dear ones, so I have the following problem, although I am leie about car hifi, but I bought jz nen ford fiesta, and I want to increase my sub and a final level, unfortunately I have only about 150€ available. Subwoofer I have this here in the eye: JBL CS1204bhttp://www.amazon.de/…/ref=sr_1_3?… The question is jz only, where do I get a final level for just under 75€? I found this one time here: Blaupunkt Velocity VA 475http://www.caraudio24.de/…/…-with-850-Wat t-RMS-420-Watt::18949.html Do these two components fit each other? what do you think about it? Furthermore, 2 more short questions, what do I have to consider when buying a car radio when I want to connect a amplifier and sub? & which cables do I need there, have seen which ones with different diameters (10mm2, 20mm2,… ) ?! THANKS for the answers in advance Sil3ent
