i got 2 mtx jackhammer subwoofers from circuit city
heres a link of what they are with stats
https://www.circuitcity.com/ssm/MTX-JackHammer-12-Subwoofer-JH451204/sem/rpsm/oid/191833/catOid/-13093/rpem/ccd/productDetail.do
i bought a 4 channel jensen 840 watt amp as well and i tried tuning it but i dont like the bass it puts out.is this amp too weak for my subs? would a 1000 watt be better for my subs or would a 1000 watt amp blow my speakers?? any help would be appreciated. i am thinking of selling or trading my amp for a stronger one. what brand is affordable but good quality. thanks

First off, you have to define "affordable" for us. I bought the Alpine PDX1.1000 and it was possibly FAR more than you want to spend, yet I can personally still define it as "affordable"... EVERYBODY'S definition will be different. Secondly, what do you want to DO with this system, meaning what kind of music do you listen to?
ANY amp would work for those woofers, but, as you have discovered, you feel you need a bit more power. This leads me to wonder what kind of enclosure do you have, because THAT amp will probably be just about enough, in two-channel mode, to drive two of those woofers. Neither of those products are of fantastic quality, and they are both... well, shall we say "optimistic", at best. Anything more, and I feel you will run the risk of blowing them.

i have the mtx box it came with. for the 2 12's.
its all sealed and has some thing on the side for the air to come out.its not a plexi glass box its just wood. my friend has 2 12" kicker cvr's with a 1000 watt xplod amp and it sounds alot louder and the bass is nice and deep and clear. i dont know if 1000 wats would blow mine. should i just try 900 watts? are mono amps better?

Again, what is your definition of "affordable"? ------------- Support the12volt.com

Well if you want to stay with MTX and the jackhammer series you could run a JH600, it would give you 600 (RMS), or 10.21 Gigawatts if your talking the absolutely non related peak power numbers.
To find a matching amplifier, you want to find an amp that can match the (RMS) rating of the subwoofers, which looks to be between 250-500 watts RMS, and they say that the box is wired to provide a 2 ohm impedance to an amplifier that you connect.
So you are looking for an amp that can put out 250-500 Watts RMS @ 2ohm's. A mono amp would be your best choice in my opinion since they will have a subsonic filter to block the frequencies below the tuning frequency of the box. Thats probably over your head at this moment, but if you want your stereo to sound good and actually understand what your looking for so you spend your hard earned money wisely, I would suggest doing some research into the electrical theory's and terms surrounding car audio, heres an excellent start. www.bcae1.com , almost every question you may have will be answered on the right hand column. ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

I would also like to add, if you don't have the time or patience currently to educate yourself on audio enough to tackle this yourself, I would definately suggest going to your independant audio shops and ask for their suggestions and see if they can find something to meet your budget and match the subwoofers. I suggest straying away from Circuit City/Best Buy and such places like that as, honestly, you probably have more knowledge than the people that work there...

i would but all the audio shops here are rip offs. charging way more for subs and amps and decks.
i know a decent ammount about car audio but just not the amp part. i installed my subs and all my stuff by myself and everything but i just dont like the sound i get from my jensen 840. i will look into a mono amp. do you think i will get a deeper and better quality bass with a 250 or a 500 rms mono amp? thanks

Pretty much anything is better than Jensen, report back when you think you have narrowed it down and we can give an opinion if you want.

wow. i came on here hoping someone has knowledge about what kind of amps go best with the subs i got but all you guys are doing is trying to get all specific about every little thing that aint got doodie to do with it.

Well... Then go buy a Zapco C2K4KW. Will it run those woofers? Damn straight. Will it blow those woofers? Again, hell yes, but you can always keep the gain down and have plenty of headroom.
You asked. You asked VERY open ended, and information lacking questions. You came here to try to get help from us, and that's all we are trying to do: help you.
It seems you have already decided on what you want to do, so... go do it. I'm done.

First, there is no such thing as an amp that "works best" with a subwoofer. Any amp will work. Second, since you get what you pay for (as you are realizing with your truly bottom-of-the-barrel POS Jensen) we need to know how much you wanted to spend. You said $200 and I have no suggestions at that low end for you. And thirdly, "getting all specific" is what professionals do. If you can't handle answering specific questions, maybe you should go elsewhere? ------------- Support the12volt.com

actually i got that jensen on sale. for 150 aha. and your crazy if you think i go to stores and pay top dollar for amps. i can just get a slightly used amp from people i know for wayyy cheaper.
so im guessing i shall go with a 1000 watt mono amp with around 400 to 500 rms. thanks

OK here ya go. You want something that will run those subs than thats fine. First dont look at peak power, its as usless as tits on your sister, just look at RMS power. You want an amp that is gonna be around 350-500 wrms. See if you can find an MTX TC3001. It runs a couple hundred bucks in store and less online, it will pound those subs to no end and give you what your looking for.

thank you! finally someone with some real answers and not more questions for my question.
the prices of amps dont bother me at the store because i can always get them half price or less on the streets. just needed to know what to look for when teaming up a amp with my subs. thank you raven

I couldn't have said it better myself. buttni69er, not only do I find your chosen handle offensive and inappropriate for this forum, your apparent promotion of purchasing gear "off the streets" has no place here. ------------- Support the12volt.com

I would have given him a 83... for the original poster, you have blinders on dude. You are only hearing what you want to hear instead of what you need to hear. I like customers like you when they come in and refuse to listen or answer questions....you end up buying the wrong stuff over and over and over again (which is good for business) instead of finding out what you truly need and buying it once. See you again when you have another problem.
