need help on speakers with factory Head unit..
also.. what about hooking up an amp? anything special i need?
If you decide to add an amp, you'll need line level converters to convert the speaker outputs from the headunit to RCA jacks to run to the amplifier input. These should be easy to find. And of course, you'll want to pick speakers to match your amp specs.
Go buy any 4 ohm set of coaxial of your choice. If you know you are going to use only the factory head unit I wouldn't spend more than $75 or so.
While you are in there I'd recommend putting in a set of bass blockers, 50-60Hz or so. It'll help keep the drivers from distorting.
