The Fubar is a pretty strong SPL sub. With enough amping power and the right enclosure, it can beat your brains out at 700-800 watts RMS.

The Boss Riot GT1500 nets out under 600 watts RMS @ 4 ohms and cannot handle 1 ohm loads. In a word, "NOPE" on Boss gear here. Just not a reliable product over the long haul.

Consider the Kenwood KAC-9152D as an option. Here, we get 1 ohm stability, a Class D MONO amp and a reliable 700 watts RMS +, depending on supply voltage. Have seen them online for under $200.00 + S/H.

What HU model is that you are looking for? The link seem not to work.

Unless you want to be FUBAR, you should first consider the box and how committed you are to this project.

That sub needs a massive amplifer, and an extraordinary box to get the most out of it. You can buy a Viper, but without a racetrack, it's just a 2 seat passenger vehicle.

If you are looking for the ultimate in subwoofer performance, I'd either recommend two 12s or one 15" woofer. There's no substitute for cone area, and one 12 might be disappointing to you if you really drive it hard.

That woofer requires about of 1kW power to run it right, so I think we may also want to consider whether or not you want to 'go for broke', or select some different speakers. What type of total budget are we looking at?

PS. Don't let the website fool ya, that sub is vented only. 2 Cubic feet for a 12 or 3.4 for a 15" woofer. You may wanna consider one 15".

what would that amp put out at 2 ohm? cuz thats what i imagine it would be used as.

That HU has a few useful features, but according to Crutchfield's, it is not a good fitment for a 2001 Chevy Cavi. You might want to look at this link and find a few models that will fit and shop them for the best deal: "What fits this vehicle"

http://www.crutchfield.com/S-wNBWNA1hV29/cgi-bin/ProdGroup.asp?g=300&avf=Y

Have recently installed a Pioneer DEH-P6800MP and a P860. Really liked the features in these HU's too. See them on e-bay for under $200.00 too:

http://search.ebayexpress.com/ps/__Car-Audio-In-Dash-Receivers_pioneer-deh-p6800mp_W0QQ_nkwZpioneerQ20dehQ20p6800mpQQ_fxdZ1QQ_ptasZ1Q2cCarQ5fElectronicsQ5fPartsQ5fAccessoriesQ5e3

The FUBAR sub is avialable in 2+2 DVC or 4+4 DVC versions. You'll want the 4+4 DVC ohm load option. So here, use a 2 ohm stable Class D amp, w/ an infrasonic filter. Again, the Kenwood KAC-9152D is a very good option for under $200.00:

http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=14934

As for power the sub requires, the specs from PA, CD states 700 Wrms for continous power ratings. PA states 800 Wrms on spec sheet.

http://www.cardomain.com/item/POWFUBR12

This would be a very nice package to build off of too:

HU: Pioneer DEH-P6800MP (~$200.00)
Sub amp: KAC-9152D ($186.00, includes S/H)
Sub: PA Fubr 4+4 DVC (<100.00 + S/H)

OK, that's about $500.00 for this side of the package plus a wiring kit and install hardware. Just plan on a solid 4 channel amp and some good speakers later and you'll have one strong system in the end.

The Kenwood Excelon KAC-X542 would be a nice match power wise for mids/highs:

http://www.bizrate.com/caramplifiers/pid425263546/compareprices__keyword--kenwood%204%20channel%20amplifiers.html (<$250.00)

Matching sub amp: Kenwood eXcelon KAC-X812D

http://www.bizrate.com/caramplifiers/pid425263549/compareprices__sfsk--5.html

What do you think about these options?

I had two 10" Fubars and I must say for the money they are great all around for the money, though from reviews I've read, alot of people say of the fubar line the 15s sound the best. As far as a headunit I picked up a new pioneer DEH-3800 for 115.00 shipped on ebay and feature wise I like it alot better than an expensive Clarion I have,it's much easier to navigate through while driving and doesn't have alot of unneccesary controls.

MrBrownstone on 09/25/2006 17:28:45
Wait guys

Are we talking the Fubr or the FUBAR? Different lines of woofer..although similar specs.

Just a side note, when using a woofer with a 1.5" surround, and teh cone is on the interior of the surround, you're giving up cone area, this is the reason I recommended 15" woofers. That 12" FUBAR is essentially a 10" woofer with respect to cone area.

Other woofer designs, with the high-roll surround, sacrifice little cone area, so 12s are a better choice.

It's up to you, but I would definitely consider a very beefy 1kW Class D amp. Otherwise, just buy a lesser woofer as you'll not be getting the most out of anyway.

Kinda like driving a Viper 55mph on a dirt road. What's the point of owning a Viper?

Victor on 09/26/2006 16:57:59
how about 2 Cerwin Vega V-max 12 http://cerwinvega.com/products/pdf/mobile/VmaxSubwooferManual.pdf

or the standard tried and tested, Alpine type R 1222D x 2...

Victor...

lukeduke28 on 09/26/2006 20:46:36
yea, the Alpine type R 1222D look like a pretty good option. do you think 2 of them could be ran with a Hifonics brutus 1206d?

swez on 09/26/2006 22:22:40
Indeed they can be... if you set up the amp correctly and use the recommended enclosure specs for these subs. A very nice combo too, I might add.

This amp specs out at 900 watts RMS @ 2 ohms and 1200 RMS @ 1 ohm loads. I would suggest a pair of 1222D's @ 2 ohms. These subs can handle 500 RMS per sub. However, if you ran a 1 ohm loads, a pair of 1242D's are the proper subs. A little strong for the SWR series subs, but a careful system setup will be safe for these subs too. One just needs to know what they are doing with amp gains, Bass boost and HU matching.

i have seeen "amp gains" on a few websites. could you explain what that means please?

swez on 09/27/2006 15:52:54
Amp gain settings are for matching the HU RCA output to the amps input stage. Most amps have sensitivity ranges from about 1/4 volts (250 mV's) to about 4.0 volts.

A typical Aftermarket HU will have RCA output voltage ranging between 2.0-4.0 volts. The idea is to match HU output voltage to amp input gain values on the amp. If you want to learn more, read this:

http://www.bcae1.com/gaincon2.htm

The lower section of this tuitorial makes more sense than the pre-rambles.

swez

PS This is one common tweak many guys don't get right. If the amp gain is set too low, the amp reaches full power long before the HU reaches its clipping point. (~75-80% of full volume) The amp may reach full output and clipping badly at 30-50% of HU's full volume.

Here's a simple method we often use for setting amp gains by ear:
