Our take on the Scosche FGA Floating Ground Adapter

by Dave Delamere

Add a high-power car stereo to your older Ford vehicle

You'd like to install a new stereo in your older vehicle, but your factory system was designed for a low-power radio with speakers that share a negative ground connection. Scosche's FGA floating ground adapter compensates for this setup, allowing you to connect your new stereo safely. You'll also enjoy your new stereo's higher power. Warranty: 1 year

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Not needed at all

Written By Geoff W., San Antonio, Tx. on Wednesday, April 02, 2014
Crutchfield Customer Review (What's this?)
Was told I "needed" this product to connect my new stereo with the old 300ZX wiring. Wrong!! Waste of money. It is sitting on my desk as a paperweight. Not worth the effort to return an item that cost this much. Like I said, waste of money. Only needed if you own a Ford vehicle, so don't fall for the "any older vehicle" line.
Crutchfield response on Monday, April 07, 2014
This car's stereo system was probably rewired at some time in the past, which would explain why he didn't need this adapter. When we read Geoff's review, we promptly refunded him the charge for the item since it wasn't needed.
