Sound good and match up well to the head unit and door speakers, the tweeter causes the factory trim to bulge slightly in the center of the speaker cover when using for rear speakers in a 98' single cab full size GMC spacers under the trim panel is an easy fix...

Pros: Quality factory upgrade

Cons:

Install went very well. Theses speakers have a brilliant sound quality, but their size leaves bass response wanting. They are matched very well with my JVC head unit (CD receiver).

Pros: Small speakers for just about anywhere. Brilliant, clear sound quality.

Cons: Small speaker, small bass.

Product Research

Features

Balanced Dome Tweeter: Each speaker has a PEI (Poly-Ether-Imide) balanced dome tweeter. PEI is a polymer film that produces a wide soundstage for superior imaging. A semi-dome tweeter has a dome placed inside a cone; balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.

4/2 Hole Compatibility: The speakers' mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Please enter your vehicle information to confirm fit.
