[QUOTE="gunz4me, post: 5398041, member: 596464"] I have auditioned a lot of systems over the past couple of months, and 90% of the time, I can pick out a class D amplifier on subwoofers WITHOUT knowing what amplifiers were installed:eek: On some of the systems that were running Class D amplifiers where I couldn't tell the difference, they were running them @ 4 ohms versus 1 or 2 ohms. Here is the kicker though.... I have to play something fast and accurate to hear a difference like: Bass Mekanik's Tocatta in D or double bass drum pumps from bands like: Disturbed, Slayer, Slipknot, Chimaira, All That Remains, Atreyu, and so forth. Anything rap, hip-hop, etc. I have a harder time telling the difference. These same systems even play my favorite Drum and Bass tracks at a level where it is hard to tell that there is a Class D amp on the subwoofers! Of course, the ultimate letdown is hearing Pink Floyd's Dark Side of the Moon sound like ***:( On a couple of systems, I was able to track it down to excessive bass boost, but that was not always the case. Maybe I am getting old or maybe I need to look through my family tree to make sure that I have no canine ancestors:wacky: Regardless, something is amiss and thus far, I have been blaming amplifier topology. Granted, I could be 100% off the mark because some of these systems were tuned by the same moron (i.e. not me) and he LOVES using bass boost! He likes bass boost so much, I have seen some of his installs where he puts it at the 3/4 mark! When it comes to class d subwoofer amps, I need something other than the usual Alpine, Cadence, Hifonics (Bxi or Txi), JL Audio, Kicker, Memphis, or Rockford Fosgate offerings that are readily available locally. I am also boycotting DEI, but mainly because I disagree with their business practices and will NOT have one of their amps or alarm systems in any of my vehicles. This is where I get stuck. Do I look at spending close to $1,000 or a little more for a higher quality Class D amplifier or do I just grab another class AB amplifier for a lot less? With the savings, I can dump more $$ into a HO alternator and another battery if needed... This whole wild goose chase is due to the fact that I initially got the wild hair to run a more efficient Class D amp on a pair of friggin 8" subwoofers:confused: [/QUOTE]
