Review: Scosche SHGM03B 1985 and Up GM Universal Speaker wire set up - 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.
Review: Chevy Tahoe - 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.
