Kicker Dual 10" Sub
You would probably be better off with something like this. I would not let a stereo shop touch any vehicle of mine, most of the installers are not qualified to wash a car, much less wire a stereo.
As an example, I was filling up with gas one afternoon and this idiot pulls up next to me and tells me he likes the car but it is a shame Dodge wasted my money with a crappy Kicker sound system. He said he owns a custum audio business and he could hook me up with a lot better system. I walked over to the POS Nissan he was driving, glanced inside, and told him to keep his shaft radio. I told him I have ZERO complaints about the car and the only people who do have complaints drive crap like this. I was ready to fight the ignorant fool. This guy and the idiots who walk up to the car and ask if that is a ding or scratch and it ends up being just dust or bug splatter really, really piss me off. Sorry, really off topic here.
No thank you needed for me.
