Contour Enthusiasts Group Archives Forums Modifications Audio Need some advice about install?

I got just the Pioneer deck installed for the time being, nice little bypass swtich hidden away too.

Quick question, the audio shop seems to mixed up the Front & Rear fade signals and Left and Right balance. (i.e. i set fad/bal to Front Left, and all sound will come from Back Right speaker).

Is this a big deal? Any sound quality issue? or any issue what so ever?

Install place was kind of far, dont wanna go back unless for major problems.

Thanks
