[QUOTE="Bert, post: 531148, member: 263"] First off, you didnt explain what problem u have.. u just asked for an opinion on whats wrong. We dunno what is wrong so what else can we say? Tell us man... From what u wrote... HU to the amp there is no problem... conenct RCA SW to channels 1-2, FR to 3+4 is ok. From what I see, you bridge your amp channels 1+2 to the audio stream (AS) x-over then the AS to the subwoofer right? IF so from the wiring you have done, your sub shouldnt be moving or if it moves, very little. You have a small little problem at your crossover. If you notice, ur x-over allows u to go high pass n low pass and there is a left n right. You do not bridge the sub at the x-over! you bridge at the amp! (Picture 52) So from amp bridged you will get a + and -, the + and - goes to one input of the x-over. so use left (or right) input + and - to the amp. THen the left output, - to the sub, + to the low pass +. SO ur wires should be white, black, black, white. (+and - to the input of left, -, + to the subwoofer) This should solve the problem u are facing, whatever it is. Additionally, you should not use the AS x-over as your amp has a built in low pass x-over which will allow u to tune it better. (Picture 55). Direct connect the sub to the amp, set the x-over switch to 'ON' and set the x-over low pass to the middle and adjust from there. Seems to be max of 240hz and low of (too blurry pic to see) Lastly, from (Picture 54), please verify that you are bridging the amp correctly. Incorrect bridging will casue the amp to have problems.
