Does anyone have any feedback about the Viper Amps (http://www.directed.com/audio/viper/amps/default.asp)? I have been buying components to replace the Blose system, and the amp(s) are the only ones left before I can take everything to the installer.
These are the items I'm putting into the system :

* HU : PIONEER PREMIER DEH-P840MP CD/MP3/WMA/XM

* Front Speakers : INFINITI KAPPA 63.5i 6-1/2"3-way (Power Handling- RMS: 75 Watts, Peak: 225 Watts)

* Rear Speakers : InfinityŽ 6002I 6.5" 2Way Speaker (Power Handling- RMS: 60 Watts, Peak: 180 Watts)

* Subs : 2 JL Audio 10W6 subs (Continuous Power Handling: 300 Watts)

* XM : Pioneer GEX-FM903XM (currently hooked up to the Blose with FM modulator.....will be connected directly to the Premier HU)

* Amps : Undecided


A local shop here in Jacksonville (Daddy'O) is all gaga about the Viper amps(they sell those). They are suggesting the 500.4 model (4 channel, 4X75watts RMS@4ohms) to drive the 4 speakers, and the d600.1 (Mono Amp, 1X600watts RMS@1ohm) to drive the two JL subs. The prices for the amps are here: http://www.mainstreet-audio.com/dire...amplifiers.htm

What do you guys think? What configuration or make of amps should I go with ?
Any help is appreciated.
