Okay, hopefully this will help you guys out decided what to spend money on.
I have the CDT Audio 61 ( I think thats the number)
I was running a hifonics zx8000 to them for the longest time, and I thought it was alright as some people said they amps don't matter "too" much in SQ, just a little bit.
So I got my Soundstream VGA 400.2 in today.
Holy ****, the difference between the amps are night and day. So much more response, clarity, my highs are now more audible, and its much more smoothed out and more comparble to a tube amp because of the harshness I had before.
Don't go cheap on your front stage for your amp, I did, and now I know the difference. My system just went up a notch in my book.
One more notch to go (viper d2500.1 / new alternator (180 amp from 110 amp) / 0 or 1/2 gauge running to the viper from a bus bar/ optima redtop) to one 15" XXX inside a 4.7ish cubes at 30Hz.
Get ready to blow up
