Style: 611UAB + 2 Speaker Package
Easy to install, even though I had to splice wires…I’m electronically savvy so it was not an issue. The new speakers sound better than my old stock Chevy Silverado 1500 ones. Good quality at a great price for the package

  • Speakers don’t fit
Style: 611UAB + 2 Speaker Package
Be careful when buying a speaker radio combo. Speakers usually won’t fit. These did not, even though it said they would for my vehicle.
