Right I'm a complete novice at this stuff. My brother has given me a active subwoofer (Fusion EN-At110) and now I'm going to get a Double Din JVC KW-AV60BT and 4 Pioneer TS-A6813I speakers. Want cables will I need to plug to subwoofer to the unit/battery. Also want the stalk adapters to work so want ISO plug do I need. If possible can you get the original mic from the Fiesta to work with new headunits if they also have bluetooth.

P.S. I'm not going to buy any additional amps. so please do not advise me of this.
