Hi all,

Can someone tell me whehter this is a good sub???

MTX ROAD THUNDER RT12-04 12" SUBWOOFER

Specifications: *200 watts RMS/400 watts peak *Impedance: 4 ohms *Magnet weight: 30 oz. *Fs: 31.3 Hz *SPL: 90.4 dB 1W/1m *Vas: 3.65 cu. ft. *Qts: 0.50 *Xmax: 9.4mm *Dimensions: Overall Diameter: 12-1/4" Cutout Diameter: 11-1/8" Mounting Depth: 5-3/8"

And this is my amp...

Kenwood KAC-626

Max Power OutPut (4 Ohms)

Normal 100 W x 2

Bridge 300 W x 1

Rated Power Output (4 Ohms)

Normal 50 x 2 (20 Hz – 20 kHz less than 0.08 % THD)

Bridge 150 x 1(1 kHz 0.8 % THD)

Rated Power Output (2 Ohms)

Nomal 75 x 2 (1 kHz 0.8 % THD)

Basicly i will build a vented box and put it behind my Toyota Camry (Sedan). Since the sub RMS is 200W and my amp only able to put out 150WRMS will there be a problems???? Is this a good match??sorry i don't know anything about audio so what you guys give me is really important...i know it's a bit of a mess reading it...but can you take a closer look at the specs and tell me whether to get the sub???

Thanks guys :)

That is the bottom of the line MTX sub. If you are on a tight budget, then pretty much your options are limited. That said, putting that woofer in a ported box would probably be your best option, unless you like the limited sound that comes from a bandpass box. I wouldnt expect window shattering performance though. If you can tell us how much you are looking to spend, i'm sure we can find you something alot better for you.

A Cerwin-Vega sub does well on 150 watts for a low price. A HED model (also their low line) has a 22Hz Fs; 6 ft3 Vas; 17mm Xmax; 112oz magnet. I use one in my family sedan and it sounds good in a sealed. You can pick one up for 50-70 $.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

No. I can't say that...don't know the cost, and haven't tried one. Just recommending one that I know is efficient with 150 watts, which is all I give to mine. Caused me to have to use a lot of sound dampening, I know that! Available at millionbuy.com

By the specs you listed I think the sub would be fine with 150 watts I would personally look for more Vas, a lower Fs, and longer Xmax in a 12" woofer. That's why I showed the comparison in the previous post. You can't tell by specs, that is for sure, but if you can't actually hear everything available, it's something to look at.

I sell those subs and infact put one in a car yesterday for a customer. For the price point I think they are a very nice sub. I put in a rockford p1 tto start with in this customers car, a 2003 sunfire, and then I put the mtx in. Same ported box and everything and the mtx curbstomped the rockford. Its a fine buy and should work well off that amp.
