So i have cerwin vega at 12s and cerwin gega 250SEs. (250s are 125w 8 ohm) (AT 12 are 300w and 8 ohm). I need a pre amp thats decently cheap and will run these guys together (A/B setup). I had a 105 watt per channel sony TA AX 295 and it started clipping when i had these two running. Need something more powerful i guess. Im new to this so i have no idea!!
