I've been thinking and reading again, so, of course, I am confused . I know I listen to 100% metal, so, I'm now starting to realize that 145 db's of bass may not satisfy me(i.e.--it may be too much). I'm hoping to get some xxx mids to be used as midbass/midrange and make kicks for them.
So anyway, in the course of all this, I ended up reading a lot about horns. Specifically, the ID cd1 pro's because they can be had at just over ~$300. So, if I get a head-unit that will give me about 18 watts x 4, using 18 x 2 for the horns and 18 x 2 for the stock rears, would the amp even be needed? At least, for the horns--the sub(s) and mids would be properly powered. The Id's are 8 ohms, just to let you know.
The problem is also this: I am a complete noob(see name). I know very little about car audio. I know horns go under the dash, however, I have no idea on how to mount them. Would I have to do any drilling into my dash to mount them? I do have plenty of space, though. I am also poor, 16, and have no money, so any purchases will not be made until I can find a job .
Finally, what kind of xover would I be looking at? Or, without an amp, would it be ok to just use the xover on the head unit, assuming it has one . Sorry for such a long post, but any help would be much appreciated.
