Yes, you will need one because the current load on this wire will be exceeded with just two of the devices you mentioned. Wire a relay like this and fuse with a 5 - 7.5 amp fuse :

86 : GROUND
85 : Remote wire from HU
30 : New remote wire ( Fuse this connection )
87 : Constant 12 volts
87a: NOT USED

Velocitymotrsport,

A quick qustion... what is the difference between the relay hook up you described above and this one.

86: Ignition switch
85:Ground
30:12 volt constant
87:remote to amp
87a:not used

Can the wires be switched around as long as they are swithed on both sides, will it work the same?

This will work the same as my configuration except that all the components will turn on when you turn the key over to the ignition as opposed to turning on the HU like ny diagram, otherwise they will do the same thing in the end.
