why not C500.1?

Systems

I've read some threads and have noticed that some people say that the Polk Carbon 500.1 does not push enough power to two 12's mm2124? Can't you just wire it through series and it should run 500 watts to each sub and that will be enough?

neomagus00

nope, whatever the 500.1 puts out (actually closer to 600 watts) will be divided amongst all the connected subs, so each 12 will get around 300 watts. 2 10s would be a decent match, though.

MacLeod

The 500.1 absolutley puts out enough power to push 2 MM2124's although its a perfect match for 2 MM2104's.

The 500.1 puts out a smidge over 600 watts so 300 per sub would be ok.

You dont wanto to hook 2 subs up in series as this would present a 4 ohm mono load and youd be getting 150 per sub. Youre wanting both in parallel.

I heard hifonics was a pretty good brand and i was lookin at their amps. 3 of their amps caught my eye. First, the BX 1205D, which is 2-ohm power rating= 1X900, so if i wired it parallel, i'd get 450 each sub (for the mm2124's).
Second, the Titan TX 1005D, which is RMS power 700WX1 @ 2 ohms, so if wired parallel, i'd get 350 for each sub.
Third, the Titan 1205D, which is RMS power 800WX1 @ 2 ohms, so if i wired parallel, i'd get 400W for each sub.
The Titan 1205D sounds like the best amp for me because it gives exactly 400 watts, which is what the sub's RMS power is. However, i've heard like underpowering can make ur subs last longer, and overpowering ur subs a little more can make them sound better. I need some1's opinion on which of the 3 i should get, or any other good reccomendations. Thanks

well, ill try the c500.1 with 2 mm2124 in 2-3 months , hope this works great...

btw,
600 Watts for bass
100 for mids
and
100 for Tweeters

i think that are ok, right?

and using that would me strange taht i blow out the speakers

neomagus00

sam - that should work out very well. go here to learn how to set your gains, and good luck!

john - the 1205D that you mentioned was a perfect match is the one you want, and i say you get that one.

underpowering, when properly done, does nothing but make the subs quieter. overpowering, when properly done, does nothing at all. either one, when done wrong, can rather easily destroy a sub (so can setting up the right amp the wrong way, for that matter).

We run C500.1's to pairs of 2124's all the time. It's plenty of power.

Systems

hows it "plenty of power"? 500 (about 600 watts) run in parallel, gives each mm2124 only 250-300 watts each sub. The sub can take 400 watts RMS.

MacLeod

Its "plenty of power" because that 400 watts is the MAXIMUM power handling. In other words thats the most she'll handle. You dont have to run a sub at its maximum rated power to get the best performance out of it. Therefore 300 watts to it will be fine.

600 watts of power is a lot of power but if youre wanting more than get an amp with the power youre wanting.

Systems

Wouldn't it make better sense to stick with the 2 10's then, and save money? If i put 300 watts into 12"s, they would prolly perform like 2 10's right?

MacLeod

Not necessarily. 12's move a little more air than 10's due to the extra cone area. Plus 12's tend to get a little lower in the frequency response than a 10 will.

If youre going to have your subs in the trunk I recommend going with the 12's. However if youre going to have your subs in the car with you as in a hatchback or SUV then I say go with 10's.

Systems

Would u reccommend getting a hifonics camp or sticking with the Polk Carbon 500.1?

MacLeod

Power wise the Hifonics is got more of it.

Thats about it. I think the Polk has superior build quality most of all, they are extremely effecient, it uses N channel mosfets like MTX uses. The Pre-EQ is specifically designed for the Momo subs. The Polk amps are excellent, top shelf amps.

The Hifonics isnt a crappy amp by any means Ive just never been a big fan. Id take the Polk amps over just about anything short of Xtant or Alpine V12's.

Systems

Wouldn't that be considered "underpowering"?

MacLeod

Technically yes but a little common sense needs to be used as well. 300+ watts to a 400 watt sub is not unusual and will still be enough power to make the subs perform well. Now 100 to a 400 watt sub and youd never get its true potential.

Youre making this too hard. If youre not comfortable with the 500.1 for your subs then get a bigger amp.

Thom

It's all in how you listen to it. I've had 100 watt amps running subs that can handle way more power than that. If you don't beat the crap out of it and clip the amp, you're fine. We've also run C500.1's to MM21214DVC's and MM2154DVC's, which is 600 watts plus to each sub. We haven't blown up subs, but when we reach the woofer's limits we turn it down a notch or two. Box design plays a part, too. If you're overpowering a sub you can put it in a smaller sealed box, if you don't have enough power you can port the box, or go with a larger sealed box. There's quite a few variables, but the bottom line is when a sub is making bad noises you're either past it's limits or you need to re- adjust the amp's gain.

LittleCar_w/12s

I used to run my DB12's at 150w (rms) each using a bridged 4ch ab amp. It takes some sontrol to not over-adjust the gain and clip. The box was about .4cf bigger than neccesary for each sub.

Honestly, the setup sounded beautiful for standard listening. It wasn't competition power, but it did put enough bottom end into the music. It actually sounded better than the d-class amp I use now. So if you underpower correctly you should have no problem at all getting the right amount of bass to, say, let that pipe organ rumble your ears off, or that bass guitar blow the napkins off the dash (true). I think your 500.1 should work well for you.

Thom,

Arent the DVC subs capable of twice the power handling of the SVC models? I couldve sworn Kim said the 200 watt rating for the MM2084DVC was 200 per coil for 400 RMS total. Is this right or did I read it wrong and the DVC subs can only handle as much juice as their SVC counterparts?

Thom

Same power handling. On the product and on the website the rating is 300 watts RMS for the SVC or DVC 10" and the other sizes are the same (SVC = DVC power handling). The DVC is a more flexible option than an 8 ohm driver, that's why we make them.

MacLeod

Whoa! Based on this reply from Kim Ive been telling everybody the new DVC subs handled twice the power. So if you guys start getting a lot of warranty claims from people trying to feed 800 watts to the MM2124...um....er....blame Kim!

They shouldve known better than to listen to me in the first place!

neomagus00

hey, yeah, whoa, i've been going off that thread for a while too... and touting it as another polk-specific achievement!!

Sorry, Kim must have been asleep at his keyboard that day, or got mis- information from someone else.

I fixed that link, in case anyone stumbles upon it that hasn't seen this one...

cool, thanks... and sorry...
