So you bought all the subwoofers and high output amplifiers but didn’t upgrade your car’s mids and highs?! Shame on you; double-check what fits your vehicle; all sizes are available in the Precision Power Sedona series. Everything from smaller shallow 4″ coaxial to strong 6.5″ premium component set. Each speaker is outfitted with injected molded poly cone and treated woven cloth surround.
