Ok so Ive had many systems in my life time.  I am looking for a 10" or 12" no more than $150.  I would prefer a 10" in a ported box.  I have a jl audio xd500/3 so 300 at 2ohms on the sub channel.  I'm not gonna upgrade amps.  I will run the front speakers off the front two channels at 70x2 or something like that. 
 
	 
 
	I can buy jl audio, alpine, kenwood, and hertz at almost cost.
 
	For example jl10w0v3 $65 ea.
 
	 
 
	So I want to know some what you all think.  I was thinking about 1.5ft^3 but I know it will depend on the sub.  Let me know what subs.
