Now I have my TTR for 2 weeks. Has Radio Concert, but unfortunately without Bose, and sounds like ́n tin bucket. Therefore I have to put myself on it again and install something cleverly. But I am still looking for a concept. I still lack a clever subwoofer solution, minrestens a 25er, better would be the still existing 30er, but without all too big restriction of the charging possibility, is already small enough the trunk. Radio I already have, with 10GB hard drive, saves the CD changer, Ne good 3/4-channel end stage also I have. Now my questions: 1. Does anyone have a clever subwoofer solution? 2. Which loudspeakers fit to sound well into than TTR or allgemei into the TT? 3. Which compilation: – Only front speakers and sub; – front and rear without sub; – then 2 way front and rear as kickbass; – front and rear and sub, that would be my idea, with the existing end stage for front and subspeakers can’t have nothing to do with it.
