Hello, I want to add a new sound system to my car (Seat Leon). Below are listed players, subwoofers and boxes I want to add: – Radio Player Panasonic CQ-C5355N http://www.preissuchmaschine.ch/product_426256.html – Subwoofer JBL GTO 1204 BRhttp://www.amazon.de/…/303-6910905-408957?… – Boxen 2x Pioneer TS-A1711 (pair) http://www.preissuchmaschine.ch/product_377169.html But the problem is, what do I need an amplifier now? I’m ready for the amplifier 200 euros. Thank you very much for your help, I really need it…
