You should think about a swap of the factory 8’ before adding any more subs.. This will make a huge difference.. And adding subs (while keeping the main factory sub) on the factory amp could lower your over all audio power out-put. The CRZ is not a “True” 300 watt system… Good luck with what ever you decide !!
