I had a set of Tenna Mind Blowers, with a Pioneer Super Tuner in my 67 Plymouth....They were great for the day, and incredibly loud, BUT........They in no way compare to the Systems that are installed now days, not even most small systems....Now dont get me wrong, I hate the attitude that some people have about older stuff...We went to the Moon in the 60's using even older Technology...Point is they were awesome, the times were awesome, and yes our memory's are being fooled by the years, and the nostalgia of it all.....A 6x9 can only do so much, even a near to perfect 6x9, which they were not even that...Thats just plain physics......For a restoration they would be a nice touch.....To the original poster of this, your Dad was right they did kick *** back then......Some of us got pretty creative with our Car Stereo Systems, you had to, because you did not just run out, and buy everything off the shelf...Same with Car Racing.....
