Questionhi there i have 2 alpine v12 4 channel amplifiers and 1 phoenix gold 1 channel amp for my sub i only have 1 rca output on the back of my head unit where and how is the best way to split my output to get optimum performance?
thanks in advance!
AnswerRichard, It depends on the purpose of the preouts. Are they simply left and right preouts, or are they just for subwoofer application. Also, I am abit confused. Do you want to use all amps for just one sub? Or do you want to use two amps for regular speakers and phoenix gold for sub? Or 1 alpine for speakers and phoenix gold for sub? Anyways, I will try and make this as simple as possible. As for the Alpines being wired to normal high/mid speakers, you should use the speaker level outputs of your stereo for each channel of one amp, and this will keep the channels separate and the balance and fader working. Sometimes, on a four channel amp, you can bridge the four channels together to make 2 channels. If that is the case, you will only run the front set of wires to one amp and the rear set of wires to the second amp. Then, you will follow the instructions on the amp, which normally uses the positive of one channel and the negative of the other channel to go to your speaker. The sub amp can use the RCA preouts, and there may be some separate adjustment controls in the radio to fine tune the power going to the sub. If, for some reason, you are trying to wire all amps to power sub, you are probably not going to be happy. Amps put power out in channels. Some have one, some have four, some can be bridged, but ultimately, you can only hook two wires to a single voice coil sub. A positive and a negative. If the sub has two or dual voice coils, you can wire a second set of wires to that coil, thus using 2 channels total, but if the channels are mismatched in any way, the sub will not perform properly. I do not think this is what you wanted anyways. So, if you need better explanation, please provide more info. Hope this helps, Scott
