Thanks Robert.
I'll look into the current draw on the head unit and the size of the fuse that is in place for the stock head unit and see if it's capable of handling the current draw. Duh... I should have known that.
I assumed that installing the crossovers in my doors would be okay but from time to time I encounter people who say that doing so never a good idea. The instruction manual that comes with Infinity car speakers doesn't really tell you much and makes no mention of ideal crossover mounting locations so I thought I'd ask.
As far as subwoofers go, I was thinking about going with a pair of 8" subs such as the
Image Dynamics ID8D4 V.3 or MAYBE a 10" sub or two. I am not dead set on any particular brand or model at this point. There aren't too many stealth sub mounting locations in the 1995-2004 Tacoma X-Tra Cabs so I'm still tossing ideas around. I'll probably just put an enlosure or two on the shelf that the rear jump seats fold down on top of. As long as I can secure the sub enclosure (or enclosures) and still be able to get to the storage compartments underneath from time to time I'm good to go.
