it looks good and everyone seems to say they are ok...are these amps good or not and if so what would be a better choice? phil

I have the Nemesis 440 thats basically the same thing ,just less watts. It's not in my car now, but it is a great amp. Those amps have a pretty low S/N and distortion rating. For $180 it's not a good deal. For the money Hifonics amps are a good deal.IMO

???im confused you say for 180 its not a good deal butthe amps are a good deal? 180 is cheap as far as im concerned..if you havea better amp for the money please point me to it..phil

i have a used memphis studio st3004 74x4 at 4 ohms. they sell new for 500 at shops. mine is 2 years old. with one year on the warranty i will let it go for 250.

I suggest a Alpine MRV-F345... I am running it, and it runs cool, and doesnt need a lot of amperage. If you want a cheap 4 channel (Less than 100 minus shipping) there is this one...

I asked and the reserve is only $95.00

I know people hate Audiobahn, but it is 75 x 4 @ 4ohms... and under 100.

Just a few good amp companies...
Alpine, Memphis, JL, Eclipse, Phoenix Gold, JBL, Earthquake, Hifonics (to a lesser extent), Directed (to a lesser extent), Rockford Fosgate (to a lesser extent), Audiobahn (not great, but if you are looking for raw power, it will do that)

Sorry, I meantto say it's a good deal.
