Hello, I'm new to DIY audio/speakers and don't know any information about my set up so I'm here to see if you guys can point me in the right path. My car is currently a 92 Honda Civic LX. I have an Pioneer DEH-P4000UB installed. You can find its specs here I also have a Alpine SWR-1242D Type R 12" Inch Subwoofer thats not installed. You can find its specs heere I was just wondering what kind of speakers should i get that would be a good set up for these components, I don't want to buy something and then find out that i broke it. I'm kind of on a low budget considering that I'm a college student but anything under $100 will be fine but if that isn't enough the farthest i can go is $150 for the speakers. Also when i buy speakers should i be looking for 2,3 or 4 way speakers? & I've tried searching up what my speaker sizes for my car but several sources keep bouncing back and for between 6 1/2 and 6x9 for the rear speakers so if anyone could clear that up it would be appreciated. Also what kind of amp should i be looking for? and lastly i like to listen to sort of indie/rock & hip hop music (don't know if that's relevant) so what kind of subwoofer enclosure should i be getting. I would like good clear sound where i can hear the singers voice but at the same time have that bass be bumping. Any help is appreciated thanks.

just to sum it up.
