## Customer Reviews

### ⭐⭐⭐⭐⭐ Scosche SHGM03B 1985 and Up GM Universal Speaker wire set up
*by E***C on April 29, 2012*

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.

### ⭐⭐⭐⭐⭐ Chevy Tahoe
*by S***Y on June 1, 2024*

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.

### ⭐⭐⭐⭐⭐ Perfect
*by A***A on May 10, 2025*

Perfect Fit a 2004 Chevy 3500
