it all depends.
Will it be worth the 1500 when the kid in high school who spent 300 pulls up next to you with his blue light special 12 bottoming out and you just grin and push the
att-off button and watch him roll his window up?
I'm not bashing guys who don't spend alot of money on their setup. If you can get some good clean sound with 300, then hell yeah, do it. If you spend 300 on a hu, amp, sub, box, and new front fill then the chances are that it sounds like a$$.
i won't embarrass anyone who keeps thier stuff clean. If its low and clean i just chill, if its distorted at all, then i hit the att and thats it.
I spend a good bit of time in my ride so to me its worth every penny.
