[Accord Man]

if your happy with the quality of the sound, but just wanna add some bass, then all you need is an amp and sub.

but if you really wanna have better sound all around, then you'll need to replce the HU, cabin speakers, add an amp and a sub.

if you dont want anything too fancy, just sounding good, then you can get all of the above for a little over 1k$ But like I said, dont expect to impress anyone, however your ears will be pleased.

a draft :
- HU : 300
- Speakers(4) : 300
- Sub: 130
- Amp: 250
- wires : 75


+ taxes + install

now this was a guesstimate, if you go shopping for an HU, you'll more than likely to want one with colors stuff.. so that may be 400$ and up.. so you know how it goes.
