Hello dear Talk company I have a problem with my system And I have a double subwoofer with 1600watt The power amplifier that was there with 2400 watts brings nothing at all. I have been attracted by the good comments. Unfortunately an error.http://www.amazon.de/…/ref=pd_sim_sbs_23_1?… I still have a 1000 watt four channel amplifier from Toxic. With this I get some sound out but when the music volume is 0 one hears clearly interferences from the subwoofe r come, something like a heartbeat pulse in the form of bass. When you flip the x over, Full, lpf, Bass 0-18 DB switch comes a whole bass inferno (sounds really horrible) no matter whether music volume is on or off. From my buddy the cheap 500 watt 2 channel power amplifier from Magnat tried out and no noise, interference or anything else. But at volume 15 the bassboxx goes off, I think because of lack of power of the amplifier. Now my question is what I best for a ve 1. A 1600 Watt 1 channel amplifier? 2. Or does it not matter if there are 4 channels? Because you can also get bridges 3. Is this right if I would make the plus cables on ch 1 and the minus cables on ch 4 from both boxes? I just want to run the subwoofer over the power amplifier. I hope you can help me
