What amp for JL 12w3v3-4?

  • Right now i have a Blaupunkt THA1250 Pnp amp it is 250 RMS at 4-Ohm. The 12w3v3-4 has an RMS of 500 W and the recommended RMS amplifier power is 150-500 W. Should I buy a new amp or just keep the Blaupunkt amp? What RMS is best for this Subwoofer?

  • The ideal match would be a 500 W RMS amplifier. You can use your current one, but you will not get what you want out of that sub. If you DO use it,be sure to not turn it up to the point where you clip the signal or you can cause damage to it. The JX 500/1D would be a great match. Good luck!

  • Correction: The amp you want would be the 1000/1 in that series. It will produce 500W at 4 ohms.

  • This is on jl's website, so wouldn't the 340 W RMS from the JX 500/1D be enough?

  • Anything will work.... But matching it to the RMS of the sub is ideal. If you tune it correctly you shouldn't cause any problems. More commonly people turn up the gain to get "max power" but don't realize they are sending a clipped signal. That can cause damage.

  • Okay  any other cheaper suggestions more in the 200 dollar range?

  • If you are certain you'll never change to a more powerful sub or run a multi-sub setup then a 2-channel amp will do you.

    Actually, I believe the Boston Acoustics GT-2200 would do you nicely.

    It's rated at a hefty 700RMSx1@4 ohms, but you should be able to limit the output to around 500RMS if you set the gain properly. On top of this, it's 2 ohm stable bridged and pumps out 900RMS@2 ohms, which should be plenty for powering most any single sub you'd ever use or many dual sub setups. Also, BA makes top notch gear, so you should be more than please with the SQ output of the JL being powered with this amp.

    That's my 2 cents.

    I was really debating buying one for myself for when I upgrade my setup, but I don't know for sure when that would be, so I'm hesitant on picking one up.

    hook that thing up!  maybe more power would help, but there's nothing really wrong with just using what you have.  those new 12w3's work well in a ported box, so if you aren't getting enough bass out of it with 250 watts, you might try a different enclosure.  that's usually more of a dramatic difference than doubling power (doubling power can be calculated to produce exactly 3 more dB's, yet a ported box can easily be 6 more dB's than a sealed).  i don't actually know if you have sealed or ported, but if you have sealed, go ported!

    I really am not the person to ask about amps so I'm reluctant to recommend one with that price range. I run a Kenwood and it works very well. I used to run soundstream which also did well. Good luck!

    i kinda like that idea...long as i get one for free! (i'm certainly not about to pay for my own image... i'm not THAT famous!)

    i'm also reluctant to advise buying a new amp here, but i'd be curious about what some other members suggested.  doesn't seem necessary to me.

  • Right now I'm looking at

    Sort of leaning toward the two Kenwood amps (not sure which one to choose, 2 channel or monoblock) but also like the JL because my subwoofer is also JL. I will be sticking with a sealed box because that is what I have just made. I would like to hook up the Blaupunkt amp but I have a 4 gauge wiring kit and It wont fit because the amp terminal is to small.

  • If you plan on just using it for the sub, get a monoblock. If you plan on keeping it sealed, hit it with a good 500 watts. Sealed enclosures need all of that power to produce well. Ported gives you extra non paid for power just like J ro says. I almost believe him....Surprise but really he has it down good. I would choose the last one you suggested if I was running a monoblock. It's basically a perfect match, if tuned correctly. Good luck!

  • I sort of was looking more into the JL, is there any problem bridging a 2 channel amp? 

  • Also looking at this http://www.crutchfield.com/S-IuMGyr86Mmp/p_065GTA1000/Boston-Acoustics-GTA-1000M.html  <Mod Edit: Linked to Crutchfield. Please link to Crutchfield's Item Page or manufacturer's website. Thanks.>

    Not sure about the price and worried about being 600W RMS when 500W RMS is the supposed limit.

  • Not sure what we can say that hasn't been said already:

    • Blaupunkt amp you have now is fine for the sub.
    • You might see marginal gain going with a bigger amp, but you would see more gain going to a ported box.
    • Bridged 2-channel amp is fine for running that sub.
    • Large mono-block amp is more efficient and would let you run more/larger subs down the line.
    • You can almost certainly limit the gain to only put out 500W from a 600W amp, but you probably can't get 500W from a 340W amp.

    Hope This Helps!!!

    Anyone else have suggestions?
