Why Upgrade Factory Speakers?

Factory speakers are typically built to:

• Provide acceptable sound

They are rarely designed to:

Common symptoms of aging factory speakers include:

• Distortion
• Crackling
• Weak bass
• Muddy vocals
• Reduced overall output

And unfortunately, turning up the volume usually just makes the problems louder.
