I was wondering what would be a good Amp for the highs in my car. I have 2 Memphis Power Reference 4 x 6 and 2 Memphis Power Reference 3 Way 6 x 9. The 4 x 6 are 30 watts RMS / 60 wats peak and the 6 x 9 are 60 watts RMS / 120 watts peak. Any suggestion for a good 4 channel inexpensive but good amp or any good amp for a good price. Would be very appreciated for the help and Thanks in advance.
