Many years ago,I wanted the loudest ,most shrill tweeter in my 76' Grand Prix anniversary Edition.In 81' I had them all...Phillips,Seas,Becker...they kept blowing.Back then,they actually wound and put the capacitors when they did 3-way systems.Today we have it made.Back then you had to have someone who knew enough math to design a crossover.My right tweeter kept blowing,so ,I got desperate ,went to Radio Shack(they used to sell car-audio)if that's what you call it and found my tweeter fix.A Piezzo Tweeter horn looking thing that would handle 150 rms @4 ohms and would go to 60K hz.That tweeter was so shrill,it would cut you in 1/2.They were like $4.99 ea.I bought 3 of them ,blew one of them.I'm not sure if they were for home or car audio but at 4 ohms I knew it would work.The doors had a 6.5"mid-bass/a 4" speaker and a 1 1/2" tweeter and 2 10" free-air mounted Pyle Drivers,the original ones.Alpine 4 channel amp /and an Alpine 2 channel amp(100 rms per channel) I may have forgotten .My claim to fame was my head unit...Alpine 7307 cassette deck-pre-amp unit with a digital-time delay unit.the source unit sold in 1981 for $565.00,it had the sendust head,cro2 oxide capabilities.NO AUTO REVERSE..The real sound quality units didn't sport the auto-reverse,and a transport system that was smooth as butter.Sometimes,the solution is simple,sometimes not.Thanks for letting me go down memory lane..Alpine had just come on the scene in 1980...Alpine50
