So I should just send the rear preamps to the fronts and just keep two front?

Oh .. Hahaha.. how are rears useless?

What do u mean tears are wasted?

Oh and one more thing ... What is the easiest way to add Bluetooth connectivity without replacing the whole head unit receiver?

Cool I keep my fader settings at neutral anyways .. So since the front signal and rear signal pre-outs have the same frequency range .. All I have to do is use the rca splitter to send a pair of rca connects to the amp for the fronts/rear and then the other to the mono block ?

I have an old KENWOOD kdc138 in my Mazda Tribute currently .. It only has one pre-out which the manual says the pre-out is for the rear/sub signal out .. Currently I have a mono block that is receiving the signal from the pre-out. What I want to do is add an external amp for the front and rear with still keeping my mono block. How can I do this all with only one pre-out? Another question is what is the difference between the front signal and rear signal pre-outs on a receiver that has multiple pre-outs?

The box is for a different 12 .... Not the square one because it's already in a sealed enclosure

I will get photos of the motor soon when I take it out of the sealed enclosure .... But I had seen if the motor had any info a while back and it didn't ... It is a double stacked magnet tho

.

So I got this 12 inch square sub for free and I wanted to use it temporarily in my tribute till I get a box built for my other 12 .. But the square one has no info on it except the dust cap witch seems to me is just an X .. If anyone knows about this sub or brand please let me know thanks

What is the difference between the 2 channel AC and the 4 channel AC? Isn't there only a left and the right , meaning the left front and left rear get the same left channel signal, and the right front and right rear get the same right channel signal ? Or is there a difference in signals given from the front and the rear?

Yea I have 1 6 inch in diameter but it's only 15 inches long and is super heavy because the pipe is from a plumbing store and i need around 22 inches in length

Is the method of using a high quality Line output converter/processor to add in aftermarket systems used by professionals in high end luxury cars?
