What do i need to hook up an amp and sub to my factory head unit?

Question

stock head unit in a 2006 scion xb for more info answer and ask for wat info you need

Answer 1

an amp kit and rca's cables

also you will need something called a line out converter which converts audio signals from your speakers into an rca output. This now enables your factory radio to accept rca cables which are needed to send audio signal to the amplifier you buy. Basically just sends music you want to play to amp.

That should be everything

Answer 2

-a hot wire to run to the battery w/ an inline fuse

-a remote turn on wire from the head unit

-a ground wire

-a set of RCA cables

-speaker wire

or u can buy a kit from a stereo store and/or wal-mart
