OMG, I am so Confused now. I swear, there needs to be Car Audio for dummies, this is becoming a science. So is there any way I can use a 5 channel Amp to power everything.

What setup would you get if you only wanted to spend a grand?
headunit
amp
sub
speakers

 

^^^^

 

Is used an option?

 

ummm news flash the head unit it self is going to be about 300 to 500 bucks. Nice door speakers are going to be about 130 to 200.
Amp going to run you in the range of 130 to 500 bucks. You can get a 10 inch sub for about 100 to 250 range. So lets say u stay in the middle somewhere
HU: 375
FS: 150
AP: 200 (to run the sub)
SB: 145
TL: 735
That does not include: the kit to hold the HU, the steering wheel control, antenna kit, the wiring kit for the amp, speaker box, speaker wires and i'm sure i'm leaving something out.
You will end up in the same boat I was in..

Now U see why I'm broke as a joke hehehe
