Limited space would take the ported option completely out of the question probably.
I was looking at this
HU.
Why would I need a better amplifier with two 400w RMS Kicker CompVT 4-Ohm when that amplifier can supply my two subwoofers with more than enough power?
Because if I am correct: Wiring up two 4-Ohm subwoofers to the amplifier a certain way will provide a 2-ohm load which will supply each subwoofer with 700watts of power while each subwoofer's peak wattage is 800w.
But I'm trying to throw as much "affordable" bass as I can into a regular cab truck without neglecting the hi's and med's as well.
Also, I don't know how to do anything considering components or how to place them inside of the door panel without butchering it completely or screwing up any of the inner-door mechanics.
