Hello, I run an active two-way system on the front and in the trunk a subwoofer should be supplied. Since I would not like to use two power amplifiers for this I bought an old emphaser EA 490-200 cheaply. I was already skeptical whether the 200 watts at 4 ohms for the subwoofer are enough for me, but because I don’t want a bass thunderstorm, but clear, controlled basses, it was worth a try. However, with closer employment I noticed that the power amplifier only four The subwoofer channel is therefore obviously only supplied by internal crossover. However, this means that I can’t control it at all with my DSP, since I don’t have a separation subwoofer to the front and I wouldn’t be able to correct the runtime. Do you think it would be possible with reasonable effort to miss the 5 channel a Cinch input? Or better sell the same and look for something suitable?
