If you’re working with factory-style doors and don’t want to start cutting or hacking up your ride, the PRV Audio 8MR400B-4 SLIM Midrange Car Speaker is exactly the kind of upgrade you’ve been looking for. It’s built with a super shallow design that fits right into tight OEM spaces while still giving you that loud, clean, pro-style sound. This is not your average door speaker, it brings that “Pro Audio On Wheels” energy so your daily drive suddenly feels like a full sound demo everywhere you go.
This midrange is rated at 200W RMS and can push up to 400W program power, so it stays clean even when you crank it hard. The 4 ohm setup makes it easy to match with most car audio amps, giving you strong and efficient power delivery without stress. Inside, the aluminum phase plug helps move heat away from the voice coil while also improving sound dispersion, so your vocals stay clear and sharp even when the volume is living at the top end for long sessions.


With a wide frequency range from about 95 Hz up to 7,500 Hz, this speaker handles the heart of your music where vocals and instruments really live. It’s also sensitive at around 93.5 dB, meaning it gets loud without needing insane amplifier power. The ventilated pole piece helps keep everything cool, while the compact 2.68 inch mounting depth makes installation way easier in tight doors. Add in the controlled suspension design and you get tight, accurate mids that stay clean even when your system is pushing hard.
