sounds like a great sub...
heard a lot of good things about polk though





butttttttt im not a fan, id rather have a alpine type x for a jl w6 or w7

[94celigts]

MTX Cheaper and same quality. Polks are very nice though but are pricy. I used to work at Futureshop. I would only go with MTX, Image Dynamics, Infinity (higher quality not entry level). JL or POLK... no others.

MTX IMO is the best for the price though

[tim86]

they look nice... ive also heard great things about polk... whatever sub you get, just match it with the correct power and youll be good I like that box and sub combo tho

[CelicaST_CALI]

bump

[CelicaST_CALI]

im thinking of powering them with this,good?:

i like that amp

[BLINKYxMUNKEY]

I like Polk.

[CelicaST_CALI]

wow thats cool blinky^^^^^ wat subs and amps are those?how do they sound,i have been reading reviews for these subs and there all 5.0 outta 5.0,only prob is how big they are.

[BLINKYxMUNKEY]

Two 12in. Polk MM2124 series running off the Polk C300.2 amp. Sounds nice and crisp. Exactly what I needed. Box was custom built to fit snug in the trunk. I have Polk db6750 components (front) and Polk db650 coaxial running off of the Polk C400.4 amp.

[CelicaST_CALI]

sounds loud^^^wat do u think of the wiring of polk?

[DaCCelica94]

i was lookin at the pic of that kenwood amp and the specs and your gonna run into some probs if you buy it because your going to be trying to run two subs off a mono channel amp.

[BLINKYxMUNKEY]

There are no problems with running 2 subs off of one mono amp. My friend has been running his for over 3 years now, problem free.

[DaCCelica94]

what i meant was you wont get as much power to both subs, i would prefer buying a 2 channel amp but thats just me

[CelicaST_CALI]

ya i thought of that,but thats around 600rms per sub isnt it??

[spolski07]

if you wire them correctly you will actually get more power out of an monoblock amp for 2 subs.
the amp see's the 2 dual voice coil subs as a 1 ohm impeadence instead of an 2 ohm impeadence, so you get more power out of the amp

[CelicaST_CALI]

wat do u mean wire right,just buy high gauge wire?that wiring diagram is correct right?

[CelicaST_CALI]

ok well i realized that these subs are 750rms TOGETHER so thats only 325 a peice....so i need to downgrade my amp.check orginal post

[cHinaman727]

my friend just got two 1200 w 12's from kenwood and a proaudo 2200 w for 350 install free XD

[CelicaST_CALI]

and wat does that have to do with this....that lucky bitch...

[97-SX]

If you wire 2 2ohm subs in parallel you will get a 1ohm impedence. Not alot of amps are stable at that but put out lots of power. That Kicker amp would be pushing over 1000watts rms but not for long. The other alternative is to wire them in series which will give you a 4ohm load which will mean you need a more powerful amp. your best bet is to find a pair of 4 ohm subs and wire them in parallel or a pair of dual voice coil 2ohm subs. both ways you can run it at 2ohms giving you more power and reliability. Hope this helps

[CelicaST_CALI]

u got a pm..im pretty sure they are 1ohm a piece...

[97-SX]

They're 2 ohm SVC (single voice coil)

Basically if you wire them in series, like in the pic that you posted, you double the impedence that they are rated at, 2ohm up to 4ohm. Reliable and efficient but you don't get many watts. If you wire them in parallel you halve the impedence, 2ohm down to 1ohm. Lots of watts but inefficient and prone to overheating. Some amps are 1ohm stable but its still inefficient.

Youre best bet in my opinion is to get two 4ohm subs and wire them parallel to get it down to a 2ohm load. Plenty of watts, efficient and reliable.

Stick with SVC if you had trouble with that. DVC is a bit more complex.

So basically series = double ohm load
parallel = half ohm load.

[spolski07]

i know the Fosgate P1000-1BD for a fact is 1 ohm stable
and at 1ohm has a rms os 1300 watts
so you could look into that amp

[CelicaST_CALI]

ya BUT on teh specs the read 750 rms TOGETHER,and then 2ohms so im pretty sure there only 1ohm,ill ask crutchfield to see wat thay say.


EDIT:from crutchfield rep:
Greg.
The Polk has one set of speaker inputs which is 2 ohms. It is wired internally for a total 2 ohm impedance

so im going to go ahead and buy these soon and put them in,and if the amp blows i will return it and get a dif one.ANd if they say it wasnt there fault i will bring out the convos of them saying it was alright

[97-SX]

Fair enough. That sounds like a good plan. I'd still say they're 4ohm a piece wired parallel internally. Let us know how they go and ask if you've got any more questions.

[CelicaST_CALI]

ok yes i have read over 50 reviews for this sub and there all mostly 5 outta 5,idk bout the amp,anyone have this amp?

[Culpable04]

off topic but I think is funny how you're all over these polk subs and you have kicker subs on your signature.


those are great subs.

depending on how much noise you're looking to make you may wanna check these subs.

kicker

they are refurbished, but comes with 90 days warranty so you can blast them out to test them. I ordered those and have them on my hands, fast shipping and they look great. will install them in the next 2 weeks

[CelicaST_CALI]

are u kidding me,200 watts peak power,im looking for somthing with more BAM,they are nice subs though,and yea i need to change it...

[CelicaST_CALI]

BUMP

[trdproven]

I am a no nonsense kind of person when it comes to sounds. First off, I want strong bass with low power consumption. Answer to this, JL W3V3 and JL 250 watt. Trust me it hits pretty hard even with a small ported box. I've had dual sub bandpass ported, sure they hit hard but imagine, I've replaced two subs with a big heavy box with a single sub with a small box, and main thing, trunk space!

[CelicaST_CALI]

and how does this have anything to do with this thread,i already picked out the subs but thx for the 2 cents...

[joehernandez]

wich subs did you got?

[tim86]

He needs to pick something and see what he likes and end this month old thread... people can give opinions all day, but you need to see what you like... go for something dvc that can take power and wont blow out easy like those polks above.

[CelicaST_CALI]

wich subs did you got?

are u serious?look at the original post..

[CelicaST_CALI]

BUMP

[CelicaST_CALI]

anyone....

[Culpable04]

I have a ZX kicker amp, but mine is 400 watts, the amp is built really good, comes with remote bass controler, so you can quickly adjust the bass depending on the music you're listening by just turning to knob instead of going thru the radio equalizer. My ZX amp is powering the Kicker subs I showed you before, and yes I know is only 200 watts peak power but they can make my rear view mirror to shake, so that's more than what I was expecting from them. the ZX amo is an excellent amp. I read the whole thread and I think you're waiting for some feedback about the amp. The only thign is, this amp is not 1 Ohm stable, but I'm sure you knew that.

[CelicaST_CALI]

ya i did thanks for the help

[itssteve]

well i think that you could have gotten a lot more for what you paid, but in the end it just comes down to if you are happy with it, but everything is nice and youi should be happy with the output

[CelicaST_CALI]

havent bought anything yet

[massbrandon]

I think those subs sound OK. Personally I think you are paying for mostly the box. There are better choices but they do definitely sound above average.

[itssteve]

^^^ i feel the same way, i mean it is only about 60$ to make a box and then you can get woffers for about 100-200$ that would sound better and get louder, but its all in what you like and want to spend your money on

[CelicaST_CALI]

ya but that box is specially made for those subs and posted and perfect,and ive never made a box b4.Its a 750 W system it will be good,and eventually i will buy 2 kickers and put them in like the yelli celi has..

[itssteve]

i can almost garenty that the box is not perfect it is prob to small of air space and tuned to high and for a hatch is is not the right aligment for the speakers

if it was perfect it would be built for the car and perfect for the woofers not just a geraric box to work for everyone and everycar, audio doesnt work that way every car is diff

[CelicaST_CALI]

well over 50 ppl out of 70 that had crappier amps gave it 5 out of 5 stars

[itssteve]

well over 50 ppl out of 70 that had crappier amps gave it 5 out of 5 stars

well im not saying that its bad im just saying that its not the best that it could be, i know going from a prefab to a box designed for the car i went up 3db this was with awsome air leaks and hatch flex from hell

there is just a better box than the genaric one size fits all
