Hello dear audio friends , I now have my first car , which is a Golf 5 . After a short time I have already become aware that I definitely need something different from the sound , because with simply the “power” and the draught of the series audio system is missing . Since I do not want to spend tons I expect nothing impossible but I already wanted to produce a better and clearly effortless sound with a little draught . I have already heard that already alone the exchange of the radio should achieve a lot, but that’s not really enough for me, so I thought that I would like to get 2 new speakers for the front, a sub and a new radio. Well my question, which components can you recommend relatively cheaply? With how much expenditure do I have to reckon with? It doesn’t have to be the best or the “thickest” sub as I said, but you should be able to notice a good difference to the original. Hopefully one of you can give me h Eleven, the topic is quite important to me, because I already hear a lot of music.
