No questions that the Mach 460 and 1000 are great for a stock system.
But any decent stereo shop could build a cleaner, louder system for half what the dealership would want for either system.
The Mach 1000 has a 2% THD, which is pretty horrible by audiophile standards, but when compared to the average OEM stereo of 5% sounds pretty damn good.
Also 6"x8" woofers are being used, which is good for high bass, but bad for midrange.
And 2.5" Tweeter/Mid is a good idea, but implemented wrong.
The cross-over frequencies were well selected,
120Hz and below to subs, 120Hz-5kHz on woofers, and 2.5kHz-20kHz on Tweeter/Mid.
The big plus is that in can upgraded very cheaply and fast with a few aftermarket parts.
