A few cars later came my beloved 75 Chevy Impala. This started out with a new cassette player, but this time it had RCA outs. I was looking forward to the day where I would be able to afford a sub-woofer and amplifier to make the thing go boom, but in the meantime I worked my way through the car replacing all the speakers and wiring. First, I put an improved speaker in the center of the dash. Then, wanting better stereo sound in front, I added some 5¼ component speakers up front. Then new 6×9’s in the rear deck. Eventually I added a subwoofer & amplifier in the trunk.
