dude, just so you know, there are TONS of sub mfgs nowadays that make stuff that will kill those terminators (oh, the irony
) and getting yourself a decent sub in a correctly built box with some power behind it will astonish you.
@BOOMINGRANDPA has the right idea about getting a truly powerful sub for around a c-note and build a box for it yourself. We can guide you on what to do with the box if youre not confident about it. I know there has been some **** thrown around in this thread, but stick around and when you have about $150 for a sub and a box, wel can get you where you need to be. Hell, if you decide on what to get now, we can advise on the box you should build for it as that literally only costs about $40 in materials and a couple hours of work from you
