Larger woofer for more bass

The REF-9603ix appeals to bassheads too, with tough polypropylene woofers and durable hi-roll rubber surrounds that deliver strong low-frequency performance. Each Plus One+ woofer sports a significantly larger cone than speakers of similar size, adding plenty of punch to the speaker's smooth and accurate highs.

Great for any power supply

You can power these speakers with up to 100 watts of RMS power — they'll work great with an external amplifier, but they're also sensitive enough to be a good match for a factory or aftermarket stereo. Plus, Infinity comes up with a safe way to get a little more power out of your system — these 3-ohm speakers combine with the speaker wire in your car so your car stereo sees actual 4-ohm impedance. Grilles are included along with Infinity logo badges that can be attached to your factory grilles.

Product Research

Features

Plus One+ Woofer Cones: Each speaker uses a cone significantly larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and increased efficiency.

Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.

Tweeters: Each speaker uses an edge-driven textile dome tweeter and a super-tweeter for smooth, accurate highs. A switch on the front of the tweeter housing allows you to boost the tweeter output 3dB, useful if the speakers are mounted in a location where high frequencies are easily absorbed.

True Four Ohm Impedance Technology: The speaker's 3-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected head unit or amplifier.

Power Handling: Although Infinity rates the 9603ix speakers at 100 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 200 watts RMS.

Q
how to top mount without grills ?

A
Joe, one more thing. Use a good quality speaker cable and not factory wiring. Reason for this is it will cut down on distortion in the sound. I highly recommend MONSTER CABLE. A little expensive but well worth the sound quality.

Joe, I was able to bottom mount (under the rear deck) my speakers using different screws and a little adjustment to the factory holes. Then I was able to reuse the factory covers giving it the factory speaker look. I have a 2002 Honda Accord, depending on you're make and model car you have you may be able to do the same, if you're replacing factory speakers. It really depends on how the rear deck is formed to fit the speakers. I will say this,,,, YOU WILL LOVE THE SOUND THESE PUPPIES PUT OUT, and if you have a power amp hooked to them, WOW!!!!!!! If you have any issues feel free to contact me here with the vehicle information and I'll see what I can do to help you get them in. ONE NOTE, make sure everything is good and tight as the bass they can produce is AWESOME! Let me know how it turns out. David

I got these and yes they do come with the grille/screen but depending on where you're installing you won't need them or possibly not have the room for them
