In my F-150 I currently have 4 component speakers (1 in each door) powered by a JL 300/4....
I then have a single JL sub under the rear bench powered by a JL 250/4....
My question: I recently purchased a JL 450/4 from a friend who needed some fast cash......
I'm going to replace my 300/4 with the 450/4 --- The 450/4 will give me more power in the front stage and equal power in the rear stage as my 300/4.....
Now --- Is all I need to do is swap the connections on the 300/4 to the 450/4? Should be the same, right?
Another "rookie" question..... Do I need to unhook the neg. battery cable before beginning even if the engine and accessory ignition switch is off?
Any other suggestions appreciated...
thanks
