Hi people, I need a final stage with about 1200 watts and best 4 channels. I got such a hiponics woofer with 1200 WATT max, 600watts duration. would like to hang the original boxes of my harman cardon system on channel 1 and 2 and then the woffer on 3 and 4 bridges. would therefore need a filter for chennel 3 and 4 for deep tones, and best so 300 watts of continuous power on both channel 3 and 4. would be a 4×300 watts level. is there something like this for about 300 euros?
