Hi all. I want to know what your opinion is about the following plan I have. Instead of buying a powered subwoofer for my home theater, I want to use 12" car speakers instead and power them with a stereo receiver. I would take the sub pre-out of my 5.1 receiver into the left AUX input of a stereo receiver and then use speaker wire to connect two or more 12" car woofers. I also would like to build a box to stick the two speakers in, or buy a box. Assuming the resistance of the speakers match the outputs of the stereo receiver, is there any fault to this plan? Obviously this isn't the most ideal or easy way of doing things, but I just want to know if there is any objective criticism you can offer me as to why any of this doesn't present itself to be a good idea. thanks in advance!
