You could also use some of that $1000 to get it installed professionally. Installing amps, and messing with the electronics in any car isn't really the best thing to do if your not sure what your doing. Shorts or fires could occur. If you want to install it yourself just make sure you research everything, from bridging amps, to ohms, to removing your stock head unit, to using the correct gauge wire. Lots to know in the electrical/sound world.
