http://www.polkaudio.com/caraudio/products/mm2154/?reviews=1

i just purchused this sub and im wondering what people would recomend to power it?

Yup, they are a nice sub. Not my personal choice the 15's.... I prefer 12's but I understand the 15's route. Can I asked how much you paid for it?

They give a power handling of 400WRMS continuous and 800WRMS peak, which is a little on the low side really. I'd be looking at feeding this around 500WRMS or a bit more with no problems at all.

I'd be looking at giving the amp quite a bit of headroom as these speakers aren't really known for their SQ, although it certainly isn't bad. I'd recommend a beefy monoblock that does around 600-800WRMS into 4 ohms.

i paid $200. yeah im interested in getting a mono block...any brands u recomend? im picking it up tuesday...yeah im not after SQ im more after doof doof :redface:

probably new the jaycar cant be beat

2nd hand on CAA you might be able to get something cheaper.

was looking at that jaycar amp.....looks very basic thou....might have to spruce it up thou soitll look good in my boot lol....other than that im tlakign to adelaide pro sound tuesday about amps and stuff

If you want doof, you want a monoblock. Monoblocks have far greater power than a standard Class A/B amp.

(Class A/B are full range amps for want of a better description - like a normal 2x150W or 4x100W. Monoblocks usually amplify no higher than 250Hz due to the design of the amplifier inducing lots of noise above this frequency, hence they are a subwoofer only amp)

Other good things about monoblocks:
1) Smaller than Class A/B's.
2) greater efficiency means less heat output.
3) You can load them down pretty well, 2 ohms is quite stable, even 1 ohm stable alot of them. 0.5 ohm is much harder to find, but they are out there.
4) You could strap 2 monoblocks to the one sub if it has dual voice coils (1 amp per coil), or even put 2 monoblocks into the ONE COIL! (Expert SPL stuff, only if you know what you are doing, and proabably need an 8 ohm coil!)
5) becoz dey is fully sik uleh!


I am running a JL Audio 500.1 slash series and it has heaps of grunt, although probably not quite enough for your application. As I stated before, headroom will make it sound better, but will also give it cleaner power which reduces the likelihood of you burning the voice coils, hence a nasty, smelly and smoky mess.

$200 is a good price for that sub. Was new or second hand? And if new, where?!?
I have said before that these speakers were overpriced, but either they had a massive reajustment in price, or it was on a runout special or something. I recollect these being about $400 or so previously.

I'd be recommending that you look to some of the more 'American' manufacturers for a decent amp that has a fair whack of power. JL slash series, Cadence, that sort of thing. I have no idea what Adelaide Car Sound stocks.....

He actually bought that from me..

How did you go waenchile? What amp did you end up getting?

i havent got the amp yet but ill be heading back up to APS soon to get that crossfire amp that george recomended! i just gotta get the money!,,,lol
