Anyone try the Zed Audio Amps- Do they sound like the Old Hifonics Series 7 or 8. What other brands are know for good sound these days. I have not been following the car audio since 1993-94 or so. It seems like the wattage ratings are way high these days and I have heard amp wth 500 - 1000 watts and it does not appear to be much louder then the old Hifonics Thors- at 125watts. Back then if you got 200 or a 300 Watt Zeus it pounded real lound and you could get by with a Rockford 75HD with 37.5 watts a channel. It appears that the brands I loved Hifonics, PPI, Rockford Punch, Soundstream are now made cheap or oversees. What brands are left that are good quality and made in the USA. I want to find an amp that pounds but with equal clarity and sound ($500 or less). I am thinking of buying something used that was built in the late 80's and early 90's, since I know what brands were good back then. There must be good brands today without spending a ton of money. Thanks for your help.
