Hi, so I have to get a small sound system in front of me, consisting of radio, subwoofer and end stage. I have almost chosen the radio the JVC KD-G611. I still lack the subwoofer with end stage. So I still have 300-350 € for this over- The manufacturers that I would prefer for the sub. would be Eton, Alpine and Ground-Zero. The end stage should then be selected according to the price and sub. And still one The sub should be in a box, or it should still be an extr a box should be bought (for that I would have some more money). And the box should take out the optimal sound, so no matter what type of design. Oh and the box should be in the trunk of a coupe. mfg privo thx aLL
