[QUOTE="PaulD, post: 4756628, member: 589636"] It's what the car came with when he purchased it from speaker works, but the reason is simple - alpine was one of the few comapnies back then that sold amp that powerful. There were 5 350 watt/ch amps, 4 of them bridged for each of 2 subs and 2 midbass, the horns had the 5th one playing in stereo. They needed that much power because in the old days you didn't compete in sq OR spl, everything was added together. You had to run thru the lanes and get judged in sq, then spl, then rta ..... with NO adjustments in between. Since the spl cap was originally 140 dB, your vehicle had to play FULL SPECTRUM up to at least 135 dB or you wouldn't have a chance at anything but local events. As for the amp thing, pls notice that I NEVER said there was no difference, I can pull out some test equipment and prove quite plainly that there are differences. The point is that these differences are not so easily (if at all) perceivable by human hearing. The other problem is that the typical distortion of speakers would most likely mask any differences anyway since speaker non-linearities are typically several orders of magnitude higher than even the cheapest of amps. Btw, Richard replaced the Alpine amps with some Kenwood amps at one time for some marketing thing, apparently didn't hurt the sq any. As for why I use more expensive brands, it has more to do with reliability and ability to handle transients, etc .. [/QUOTE]
