    Default momo 12" sub #5 being sent back to polk

    yes, thats right, to add to my amazing luck, ive blown a sub
    well actually, a few weeks ago i posted that my amp blew and i sent it back to RF and they said they fixed it, but im not sure if anything was wrong with it b/c i just automatically assumed it was the amp because of my infinite faith in Polk
    well i go to install the amp today...ive had it for like 2 weeks and its just been in my room sitting there
    and the damn thing wont even turn on
    i switch the power wires and the REM wire from another amp that was working to the one that wasnt
    nothing
    call RF
    after another 30 minutes of trouble shooting over the phone...nothing
    i get an RA number and they send me some UPS thing to my email that i print out and put on the box so it doesnt cost me money to ship
    well one of the things i did over the phone was switch out fuses, even though the one on the distro block did not appear to be blown
    so i switched, still the amp would not turn on
    well i get off the phone with RF and go to reinstall everything i have pulled apart
    now the amp for my components wont turn on
    at this point im about to kill somebody
    i troubleshoot it with no results
    i take out the fuse and replace it with another one
    comes on
    and im like hey...this might be the fuse i used to test the 550S that i just got back from RF
    so i get another fuse and put it in the distroblock going to the "blown" 550S
    success
    it turns on
    turns out the fuse that i originally had was blown
    and the fuse i used to test it with was right out of the distro block of another amp that was working
    well i guess when i snapped it in it broke as well
    none of them appeared to be blown, but they were
    at this point im think...alright! everything IS working
    hook it up to the speaker
    nothing
    wtf?
    switch out some wires on the amp even though im 99% sure theyre right
    nothing
    so i hook it up to the sub that is working
    the sub starts playing
    at this point im thinking maybe the wire somehow came off the terminal on the inside of the box, either on the sub itself or the spring-loaded terminal on the box
    i mean i did take the grill off, even though i did not move it at all, i didnt think i did anyway...i had it upright when i took it out so i wouldnt have to mess with it
    well i take the sub out and hook it up directly the speaker wire on the amp
    nothing
    at this point i knew...the mm124 was dead
    i press the cone in and it sounds like sand paper
    im guessing the voice coil is TOTALLY FRIED
    i have never heard a speaker sound like this
    if i hit it kind of hard i can actually hear the metal that has come apart
    sounds like a spring almost
    so Polk is getting a call tomorrow...its still in warranty for another 3 months...lol
    i am just having one awesome week...

    I had the same problem out of my dx104 subs. All 3 that I had did the same thing as you describe. So, I took one apart and the voice coil former was broken. I have never had good luck out of the seven 10 inch polk subs I have had. Now the 8 inch polk subs I have had, (3 in all, 2 db and 1 dx) have all performed admirably.

    I currently have 2 mm12's and haven't had any problems out of them. I have owned them since August of last year, but they haven't been used since february. I put 6 months of good use on them and never had a problem. The reason I took them out is because the electrical system in my car was not able to supply enough power for my amp.

    Currently I am running two 8 inch resonant engineering subs in a 1.6 cu. ft. ported enclosure tunned to 34 htz. With this setup I don't draw huge amounts of current and they sound just as good as the MM's did.

    man, cody, this is just not your month. all i can claim is a soldering gun burn and a 4x6 to the jaw... kinda strange how all the bad stuff piles on all at once, huh?

    ive figured out why its all happening at once
    its because our school is giving out a 2000 mustang, and im going to win it
    but i have to go through a lot of misfortune first so it evens out

    Reminds me of the time I grabbed a soldering iron by the wrong end. That's a mistake you never make twice.

    Good Luck!

    HEY! That's not funny! I drive a V6 5 speed mustang. Hey, it's not the fastest car, but for the money, you can't beat it. Especially since the Camaro and Firebird have been discontinued. It's like the Polk of the car world. 200 horsies for only $17k brand new. No more dissing Mustangs allowed :)
