I'm looking to install an amplifier and speakers into my TL-S. I want to keep the stock deck so I can retain use of the steering wheel controls. I'm looking to connect the wires from the deck into a pair of line-level converters and then connecting these to the amplifier which will then connect to the speakers. Can the deck be attached to a set of line level converters and then into an amp? I know Bose systems tend to be incompatible with other components. Also, for the front speakers, I would like to put in component speakers. Where can the tweeter go without it looking conspicuous? I would appreciate any tidbit of information concerning the TL-S' stereo system. Thanks!
