Hello, I want to “build up” the sound or mainly the bass in the car. I want to “fit up” a subwoofer or a hifi box into the car. I need a power amplifier for this.. However, I don’t want to spend more than 80 euros for the power amplifier. (I know it’s little but I’m currently short of money –> holiday ) Today I was in the media market and this power amplifier was recommended to me : http://www.amazon.de/Renegade-REN1100S/dp/B000UL2Q2Y The data from the HiFi box, which I’m looking for my car radio : http://www.testsieger.de/produkt/alpine-cde-126bt.html My question now : What do you think of this “set” or the final stage? What additional subwoofer would you recommend to me? Thank you in advance for the answers!!
