I have a 03 Dodge ram Quad cab and I planning to install a system in it. I have a custom made box for going under the rear seat. I have (2) 10" Kicker CVR Sub woofers. I plan to use one amp for each speaker. I have a JBL BP300 and a Audiobahn 2300. I think the Audiobahn would be plenty for both speakers but I not sure. Plus what gauge of wiring would I need for the Battery terminal/Ground terminal and size gauge speaker wire? I read that hooking up the speakers in parallel would make them louder. Is this true? So what do you guys think would be the best way to hook this up???
