But unfortunately they have a power deficit with volume but especially in the sound and that drives some drivers to other radios but then it doesn’t sound good and then everything is converted for a lot of money. Everything just because you can’t connect an amplifier to the radio or better said. Many don’t know that there is a solution on the market for this now. Calls itself High Low Adapter and there are 2 or 4 channels. That converts the sound signal in chinch data so that you can connect an amplifier to the radio. I haven’t tested it yet but I want to connect a HU-605 to a 4 channel mini amplifier, that’s enough for me because it’s about more bass so sound and not that my mucke already 2 minutes before I arrive at home with the neighbors. But there is also something already finished :http://www.ebay.de/…/191590872522?… I have ordered something now and if I have built it up I will report it here. Selfishly I was looking for a 80er/90er to get the radio amplifier to give me a better performance and I’d something to keep up with the radio.
