Important Note: Polk Audio specifies the nominal impedance of these speakers to be 2.7 ohms. The product box states the impedance to be 4 ohms and the speaker magnet shows 2 ohms, this has been confirmed by Polk Audio to be an incorrect specification. The product manual is correct in stating the nominal impedance of the MM series of speakers to be 2.7 ohms.

Best combination of pricing and manufacturer authorized retailer. It's also one heck of good component speaker system.

Looks as if it will work well for ATV/Utility Vehicles for outdoor use.

I already own some of these. Best sounding. Best value.

I own the MM5251's and liked them. Thought I would try the 6501's.

Is the Hifonics X200.2 a good amp for this set of speakers?

Best Answer: Hi James,

Great match! Well done.

The X200.2 is providing 100w @4ohms & 200w @2ohms , where the Polk Audio MM6501 are running @2.7ohms , which means the speakers will land somewhere in the middle surely getting at Least the ~125w RMS the they are asking for.

If I bridge the two rear channels to run a single 4-ohm subwoofer, can the two front channels still run a pair of 2.7-ohm component speakers reliably? Thanks!

Best Answer: Hello Dave,

Generally speaking, we do not suggest attempting to do so. However, IF your amplifier has the ability to run properly with such a setup, then the user manual will imply it. Even with that said, for amplifiers that say they Can [e.g. Rockford Fosgate R600-4D] we typically still do not attempt it out of reassurance that we aren't stressing the amp. Nevertheless, check with your manual and/or the manufacture.

Best Answer: It would work just fine. The lower impedance of those speakers up front will eg more juice than normal 4 ohm speakers would. The sub would only get about 150rms so match it up accordingly if you're buying that as well.

For this set up, how much power does a tweeter have and mid driver have? it is 125 rms. are they both 125 rms or half each?
jhay1423 on Jan 20, 2016
Best Answer: The 125 watt rating covers the entire audio spectrum for the tweeter, woofer and crossover when used as a package. It's easiest to think of the woofer, tweeter and crossover as one single driver electrically.

If you want to learn more here's some info:
Power handling ratings only matter in context with the sensitivity of a speaker. For example the polk tweeter might only be able to handle 20 watts, while the woofer handles 125. You'd think this would make the tweeter a weak link, but that's not necessarily the case if the tweeter is much more efficient.

Speakers sensitivity is measured by how loud they get from 1 meter away when you feed them 1 watt of input power. There are other standards of measuring that but I'll stick with the most common.

Let's say the tweeter is 97db/1w/1m. That means with 1 watt it gets to 97 decibels from about 3 feet away. That's actually pretty loud for high frequencies. Now here's the trick, every 3 decibels louder you go you need TWICE the power. So 100 decibels takes 2 watts, 103db is 4 watts, and so on. It seems pretty easy to get loud!

Now let's look at the woofer, let's say it's 91db efficient. That means to get the woofer to play as loudly as the tweeter does with only 1 watt it takes 4 watts. Still pretty loud. When you play a song and hit 125 watts the crossover is feeding four times less power to the tweeter than the woofer in order to match up their sensitivities. So the WOOFER might be getting 125 watts of bass here or there but the tweeter in our scenario would never get more than around 30 of high frequency power.

what depth is required to use the top mount tweet cup?
Linux User on Jul 30, 2015
Best Answer: Not sure I didn't measure and I can't locate the manual at the moment but I would say roughly about an inch I mounted them in the front kick panels with no problems

I have a Subaru Forester 2011 and currently have DB6501's in the front. Will I have to make any modifications to replace the DB's with the MM's, or is it just plug and Play?
Robert H on May 5, 2015
Best Answer: As long as the dimensions are the same, I do think think thee should be a problemon swapping them right out. You may want to use the amps that come with the MMS for best results though
