Call me a n00b or whatever it is internet geeks are saying these days, but somebody help me out. I drive a 2000 Land Rover Discovery and I'm looking to get some beat in the trunk. It's a daily driver, so it's not for comps. I'm wondering if 1 SSD15 is a good choice. I'd get two, but, military man+2 kids= small budget for car audio. I can afford 1 SSD15, but is that the best choice? Suggestions? BTW: Don't suggest other brands, I only want Fi. So it's Fi or nothing.
