Im buying 2 brand new 12'' Kicker subwoofers with a 1000 WATT amp for my 2007 Dodge Caliber..the problem is...I don't know exactly EVERYTHING else I need for this project! ( like the wires..or anything else really! ) I downloaded the manual to install the wiring and directions for my vehicle from MOPAR, but am still not sure what to ask when goin into an audio store! I really don't know where to start! any help would be appreciated!
