i like the new subs and head units(for mp3 and adjustability, we all know os denon is the shhhh) and old amps and processors, i like the control of the os processors and eq's, and the amps just seem to have a better sound to me poersonally, not saying you cant get that with new stuff but there just isnt enuff companies making them today. yea and people do argue about which is better. i have and have had many amps new and old. in my old work car i did comparing with amps. out of 6 amps i tested on my highs. the top two imo were os. also used new rf vs old rf and new crossfire vs old crossfire. and you can notice a differance i dont care what you come up with mathmatically. try it yourself dont take my word for it. the five amps were 1 punch 200 dsm, 1 punch 2002, crossfire vr302, crossfire cfa 202, audio art 752(blue), and hifonics zues(maxxonics). here is was i came up with
the best sounding amp was the audio art buy a good bit next was the dsm followed by the rest. the crossfires really were hard to tell apart. the 202 was even about as powerful as the vr302.
now all tests were done full range using no xovers etc.
well you can argue points all day. but for my opinion i will run os class a or a/b unless i was into spl comps then i would go with new class d for subs. but in one of my cars im running a os us amps 400x pushing 2k-2400w to my re sx 10s and two os mtx amps on my highs. thunder 304 that does about 100x4 @4 and a thunder 252 for my tweets thas does about 50x2@4. so im pushing a good 2400-2900w roughly. h/o alt with bat in trunk and 1/0 welding cable. very very slight dimming running full tilt at idle. when driving i get no dimming. so if i need over i would say 3k or so i would probably use newer class d but if i dont need to then im sticking with my os amps. if you do your own test do it right, not on subs. rull range on a good set of coax or full range woofers. allow nothing but those speakers to play in the car. use the same songs for all amps etc.
