ALPHASONIK MPRO658 6.5" midrange car speaker pair 350W RMS 8 ohm

Midrange driver for car audio

The ALPHASONIK MPRO658 is a 6.5 inch midrange speaker pair built for automotive sound systems. Each unit handles 350 watts RMS and peaks at 1400 watts with an 8 ohm impedance. A neodymium magnet and paper cone deliver 95 dB sensitivity across a 100 Hz to 8 kHz response. The pair suits enthusiasts who want clear vocal and instrument reproduction in a factory or custom location.

Fits standard 6.5 inch openings

The speakers mount in a 5.73 inch or 146 mm cut-out and need 3.03 inch or 77 mm mounting depth. Overall diameter is 7.07 inch or 180 mm and overall depth is 3.62 inch, so they sit flush in most door panels or dash pods. The 8 ohm load eases amplifier matching and leaves headroom for additional drivers in a multi-way system. Installers must supply their own crossover network and wiring.

Handles midband with authority

With 350 watts RMS each the pair reproduces vocals and lead instruments cleanly at high output levels. The 100 Hz low-end limit means a separate subwoofer is required for bass below that point. Sensitivity of 95 dB lets moderate amplifier power reach loud listening levels without strain. The 8 kHz upper limit calls for a dedicated tweeter to cover the top octave.
