Ok... here is my situation:
I bought a new Boss head unit 822UA to install in my friends 2004 Mustang tomorrow. (I know it's not a great unit... but good enough for my friend without a working CD player right now)
I also bought the Metra 70-5521 wire harness kit....
On the back of the new Boss HU there are 2 sets of RCA jacks Rear & Front... I am told this is for the amps.
The smaller wire harness included in the Metra 70 5521 has 2 RCA jacks (one white & one red)... a stereo shop said he thinks the red & white RCA plugs coming off the Metra 70 5521 should "probably" connect to the "Rear" RCA jacks on the back of the Boss HU... but a YouTube video on how to install a new HU in a 2004 Mustang said to connect the Metra 70 5521 RCA plugs to the "Front" RCA jacks on the new HU.
Anyone know which advice I should follow?
I read other posts that say different things and now after an hour or so of reading posts I am very confused?
And... If I connect to one set of jacks... and the sound is lame... will it sound better if I connect to the other set of jacks... telling me or confirming to me that those are the correct set of RCA jacks?
Any help would be appreciated....
