MTX RTX88

Overview

Our take on the MTX RTX88

They'll hear you coming
Are you looking to play your music loud? If so, you'll want to check out MTX's Road Thunder Extreme speakers, which use PA system technology to bring concert sound levels to your car. MTX built the RTX88 8" midbass speaker to fill in the frequencies in between where your tweeters and subwoofers play. And, believe us — this incredibly efficient speaker will give you plenty of volume when you feed it some serious power.

Built for high power
The RTX88 handles up to 150 watts RMS thanks to its hefty magnet, treated paper cone, and cloth surround. You can also easily run two of these 8-ohm speakers with a single amplifier channel, great news if you're installing two in each door. You can install this speaker in an enclosure if you want, but it works great in a free-air applications.

Note: This package contains one speaker. You'll need an external amplifier to drive this speaker properly — an in-dash stereo won't have enough power.

These are great speakers, especially for the price. I am very happy with my purchase!

Crutchfield Customer Review (What's this?)

Speakers are very good. They were not an exact fit, so some deck modifications were needed. That was unexpected. Also, was not provided the correct adapter plugs to fit the Volvo wiring. Had to make do on my own.

Crutchfield Customer Review (What's this?)

I was looking for new speakers for my old, BEAUTIFUL Advent Speaker cabinets because 2 of the speakers were blown. i accidently happened upon these speakers. Didn't even consider they were for cars, the specs said they could do what I needed so I bought them. The 2 I bought sounded so good in my cabinets I purchased 2 more to completely replace the speakers in my OLD BEAUTIFUL Advent cabinets. All I can say is the speakers sound Delicious. Of course as soon as I installed them I had to crank them to see how they handled the heat. They handled it beautifully in fact, they sparkled. I would recommend these speakers to anyone.

Pros: Excellent price, powerful speakers, very good sound.

Cons: They were TOO easy to install!!!! LOL!!!
