I think this thread is retarded.
The jl will get louder and sound better with such a less impact on your electrical system.
The hdc3 is going to beat your car up, beat you up, and **** your electrical system if you dont have one to back it up.
all in all i wouldnt be surpised if the hdc3 actualy cost you more in the long run.
although price isnt a factor, or so you say, it is.
what are your goals, do you want to sit in your car and get accurate music reproduction or do u just want that bass u can hear 5 blocks down and show off to the old people driving there cars next to you?
