Ohms question.

How do you know how many ohms you have in a stock car? And how do you make it so your amp is running at the ohm you need it to run at? I have a 05 Mustang with the Shaker 500 system, and I need to have my amp running at 1 or 4 ohms. I'm going to use a line-output converter to the rear speakers. Does anyone have a diagram to explain this to me? Also, is it worth getting a new HU so I don't have to use a line-output converter?

uhmm it dont matter about ohms at your point, a amp dont make the ohm load the speakers do, and all/most car spekers (stock) are 4 ohms... if you get a amp that is say 1000 watts X 1 @ 1 ohm you need a 2ohm dvc sub..

those 1251t's sound horrific just to let you know they get a little loud but sound horrible doing it. if you have 1 of them you can wire it to make either a 2ohm or 8ohm load two of them you can get it down to a 1 ohm or a 4ohm load http://www.jlaudio.com/tutorials/wiring/index.html#2dvcsp how to wire
