Looking to upgrade my amp for upcoming IDMAX install. Currently running Cadence Z9000 for 800 RMS into 4 ohms. Looking for 1000 or 1200 rms 4 ohms Class A/B only. Limited by 20" length for install. No Class D--I have a Planet Audio 2250 that pumps Class D power if thats the way I must go. Anyond need some Xmas cash?
