14 After the strap was in place the e-brake was ready for service without damaging our new audio components. Well after we buy a new cable that is, but the pedal doesn't hit the speaker and that is the real point. Now the stereo in the car is actually a stereo. We have noticeable left to right imaging and all our music sounds so much better. If you are a guy who likes bass we would recommend lining the back of the kick panel with some sort of sound dampening material like DEI's BoomMat. This will stop the speaker from vibrating the kick panel and in turn let those vibrations become bass.
