"really nice interior speakers" & "I do not want a box"

I dont see how these relate bro.

Interior speakers are the front 6.5inch and rear 6x9s.. if you want to also install a subwoofer then that's where you would need a box and think about how much trunk space you want to lose.

So which is it? Do you want interior speakers only, interior & subwoofer, or subwoofer only?

Lastly.. budget.

Interior speakers = $_____ <-- what's your max price to spend
Subwoofer = $_______ <-- what's your max price to spend
