Upgrading front doors of 2002 Ford F350 XLT with stock head unit. As compared to the stock speakers (which I left in back), these have bright tweeters, and tight bass. Stock appears to have better bass than these, but it is muddy. Honestly, stock speakers I could not hear ANY symbols...plop these units in and holy cow...there they are again!!! These may perform better at the low end with an upgraded head unit and an amp, but with stock head unit, don't expect huge improvements in bass. Overall, these speakers are clearly geared toward bright highs, and tight bass, but are lacking the mid-range...which can be OK, especially if you tend to boost those two ranges anyhow.
Pros: Clear tweeter, tight (albeit limited) bass, great price, perfect fit!
Cons: Limited Bass, tweeter little on the bright side, no midrange.
