This post might help if you are looking for mid-bass replacements.

Thanks Filippo. Did you notice a big difference when you installed the Hertz mid-bass drivers? I have a small alpine power pack amp driving my fronts. The bavsound upgrade with the amp is louder and clearer than stock, but there’s literally zero bass response with the stock mid-bass. They also limit the amount I can turn up the gain on the amp as they are the first to break up with distortion.
