So your wanting a good price, with a pretty decent system. Go to alpines site, and build yourself a system. Type s speakers are going to be best for you from the sounds of it. They have 4X6 for the front 6x9 for the back. Then just select your head unit. If you want, you could put in a sub semi cheap. But if you plan on doing it later, go ahead and drop the rcas from the headunit now. Get the wire harness and mounting kit, USE THE SEACH BUTTON! To find the how to for all this, and an hour-2 hours you'll have a completely new awesome system installed.
My system is kenwood exlon head unit, kenwood performance amp for the custom mounted 6 1/2 componet type r in the front and 6x9 2 way type r in the back. Then 1000 watt alpine amp for the 12 type r sub in the custom fiberglass box. It all bumps, really well, and I can't pull any distortion on the cabin speakers, but it costs. So depending on you want to do, for me to get the 4 channel amp, then good speakers to handle it. It adds up super fast.
