Why replace your factory speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Crutchfield Customer Review (What's this?)

Bought 4 as a replacement for aging factory speakers in an '02 Tracker. Factory stereo, sounds GREAT, cleaner, louder. Great bang for the buck. They said the speakers were exact replacements. They were in respect to size, but far better in resect to sound.

Pros: love the adapter wires. no splicing!!

Cons: none
