Hi… have a CCTR700 telephone radio with changer in it. I would like to use this as a basis because I stand first on original cutout and 2nd I did not find a reasonable telephone radio. I don’t want a hands-free system because there is no reasonable for my Samsung E700. (Anytime no found) So now to the natural question. I have to replace in front of the front boxes with Velocity VR172 or with Velocity Neox170. In the back I don’t really know what to take. But think that there Velocity VR132 will be sunk. In the wheel pit a sub will be sunk where I still have no idea which one. Because I have no idea how much volume sun box has. The original floor of my combination also flies out and will be replaced by MDF. This also gives me enough space for the amplifiers. Since now all boxes with amplifiers should be operated the question is how much watts I need. The sub should not be so strong, it should only sound reasonable. How do I take the audio signals off the radio. I think that if I put the original outputs on the amplifiers, it’s the key. Do I have to put new cables for the boxes or do the old ones? Which sub would you recommend for wheel chucks. Which amplifiers (or is one enough?) do I need for this box combi (boxes + sub). I think that’s enough for the first time. I want to say that I don’t want to have a Hifi show car but rather n I also think my radio is ok for it, because I want to run all the boxes over amplifiers. So now good night and thanks for every advice. MfG Furrball
