Scosche SHGM03B Car Speaker Wiring Harness Adapter - Compatible with Select 1984-2009 GM Vehicles - Car Audio Wire Harness for Aftermarket Speakers - Sold in Pairs - See Guide Images for Vehicle List

I purchased the Pioneer 1674 speaker set along with Scosche SHGM03B 1985 and Up GM Universal Speaker wire set up. This made installing my speakers in my 2000 Silverado, a piece of cake. I snapped my speaker wires into the universal wire set which made installation so easy. No soldering or crimping of wires. I used my factory speaker retainers and popped them into the door. No screws! The speakers sounded great. I new my old ones were bad but I didn't know how bad till I heard these new speakers. Wow.

Used this to wire rear tweeters in my 2007 Chevy Tahoe. Hooked right up to the aftermarket speakers I was using and worked flawlessly. Highly recommended.

These adapters plugged right into factor speaker wiring harness.

I used this harness to install after market speakers in a 2011 Impala. The connection from the harness to the car, is a REALLY tight fit! The harnesses connectors for the after market speakers are REALLY small! I ended up cutting them off and using the ones that came with the after market speakers. I didn't give this harness a 5 Star rating because of the small connectors, but the harness worked for me and I'd do recommend this product.

Perfect Fit a 2004 Chevy 3500

These speaker harnesses are awesome. The thing I tried to look at the most when reading other reviews was the year and models people were using them on. So here's mine: 2000 chevy silverado (new body style in that year). It is nice to have an adapter that I just plug into the trucks wiring harness, and in the future when I need to swap or replace the speaker I am not having to cut and resplice a bunch of wires.

Does not fit 2006 Pontiac Grand Prix Gt with Monsoon.

fits on my 2012 impala. fit the stock wiring harness just about perfectly- was a bit tight, but went- same on the other ends(s) was a bit tough getting em on the speaker terminals- but again went, with coaxing. Note- the speaker ends--- the wire is split on the speaker end and has a small and large female "speaker" slide on thingie terminals. which matched my new speakers perfect (jbl)...so if your speaker have those standard plain terminals (one small, one large)- you're golden. PSS- i dont think the picture is correct either

Used for a 2000 Chevrolet Silverado 2500, way quicker than just hard wiring new speakers in. Plugged in directly to the factory harness

Bought for my '08 Cobalt. No issues at all, not really much to say about them
