Subwoofer

Hey, I've got the ginormus sub woofer thats crazily loud. But the computer doesn't make much use of it, it will only work if the bass is super deep. When i plug it into my ipod it works normally. Any help to make it work better for my computer because it was originally made for my computer?

Limit of a subwoofer

Guys the question sounds like stupid but the thing is how should i know a subwoofer reached it's max excursion limit before blowing the coil.If it starts to distort does it means it reached it's limit or the amplifier can't provide much juice the speaker needs.

​Can a Pioneer GM-A3702 Two Channel Amplifier drive Pioneer TS-W306R 12-inch Subwoofer.

I want to know will the loudness of the subwoofer be loud enough. I have bought this two products but even on the highest gain setting of the amplifier, the subwoofer loudness is very small. The sound from the sub is like, driving from a LM386 op-amp. Thank you.

Bridging two identical amplifiers to increase the rms output power Answered

Hi, i was wondering  if i can bridge two identical amplifiers, to drive a 4ohms 400w-rms dvc subwoofer, the second problem is what about the power supply, i don't think i can use one 24volt car battery for the two amps so can i use two separate car battery, below is the amp i want to bridge. JBL GX-A3011SI 1200W Class D Mono Car Subwoofer Amplifier. Product Info: Low Distortion Class AB Design Active Low Pass Filter Noise Rejecting Differential Inputs Filter Range 30Hz to 320 Hz Peak Power Output  1200 W 4-Ohm Power Output  200 W RMS x 1, <1% THD+N 2-Ohm Power Output  300 W RMS x 1, <1% THD+N Design Low Distortion Class AB Input Variable Line Level and Speaker Level Signal to Noise Ratio  93dB since the output rms @4-ohms is "200 W RMS" so bridging two of this amps will give me a 400w-rms. Thank you. Regards

Choosing a home amplifier which could handle a car sub woofer

Well i want to know what type of home amplifier i could choose and buy that i could hook up a car sub woofer and then i could mess with the frequencies so i could get that boomy bass in my home and have 2 speakers on the side. i have tried finding such thing but im not sure if this one is good and could give the two sub speakers enough power to give it those awesome vibrations. the link to this amp ishttp://www.amazon.com/Dayton-APA150-150W-Power-Amplifier/dp/B000VKXLBO/ref=sr_1_21?s=aht&ie;=UTF8&qid;=1293251962&sr;=1-21

sync bass with subwoofer

Hello, I thing this is the right /r/ to ask this. I have a HTiB and I want to make 2 led strips with ~6 meters blink with bass. I have done some tests with my old subwoofer (logitech z5500) and I noticed that as the bass goes deeper, I got distorsions... I have read that we can use an amp to store energy (? :S) but it could start a fire due the heat. Can someone help me? Obviously I can use the leds directly conected to the subwoofer and dont turn the subwoofer volume to high and everything will be ok, but I really want to make something cool and safe. The HTiB this an Onkyo HT-S9700THX, and the subwoofer is powered directly to current, the amp just pass signals. I thing this is called a pre-amp subwoofer, correct if Im wrong please. Regards and thanks!

What type of amp should I use for making a boombox? Answered

So I want to make a boombox similar to this instructable, https://www.instructables.com/id/DIY-Portable-Boombox-Audiophile-Quality/step15/Assembling-The-Boombox/   but more simplified.  The problem is I know nothing about speakers.  Im planning on buying 2 6.5" subwoofers with an RMS power rating is 150 watts and the peak power rating is 300 watts and the impedance is 4 ohms if that helps. I also want to run two full range speakers from the same amp and im planning on using two old ones I stripped from a radio, the only thing I know about them is that on the back of them it says 8 ohms and 2 watts.  I would also like a volume control on the boombox if that makes a difference. I have tried to look up what type of amp I would need but haven't had any success.  If someone could give me details as to what type of amp I should buy or point me to an instructable that shows how to make an amp suitable for this type of project it would be greatly appreciated.

Can I add a subwoofer to a stereo system that has no subwoofer?

I have a stereo system that has a left and right speaker that connects to the main part of the stereo (CD player and the radio). I was wondering if I could disconnect the speakers, from the CD player itself, and make a circuit that amplifies a low sound bass, then connected to a small subwoofer.  (Instead of a normal amplifier that just makes treble sound louder.) Then reconnect the two speakers so the final result is that there is an amplified subwoofer.

Subwoofer lost its "WOOF"!!!

So i purchased a pair of 800w 10" subs at a yard sale for 20$.  They were cheap so i assumed they were faulty but figured i could try fixing them. So i get them home, hook them up to an amp and nothing happens... until i place a little pressure on the cone and  thump thump thump, they work... and they're heavier and hit better than a pair of 1200w 10" Sony Xplodes i have... until i let go of the cone.  I'm reading things about blown voice coils and what/not and was hoping someone had an idea how to replace one. Or if my problem sounds like something else all together.  Any ideas DIY'ers???

How to set up a powered subwoofer pc speaker set, without the powered subwoofer?

I have a set of pc speakers, no mfgr markings, that were to include a subwoofer. Given to me without the subwoofer. Only reason I know about subwoofer is one side has a port that has printed next to it,"to subwoofer." I'd like to just make it into a set without the subwoofer. It has 3 stereo male plugs, in weird configurations, and I think it may need rewiring. Also has a volume "wheel" switch on one speaker. Oi, this is too much trouble, isn't it? Well, anyone have ideas, even if your suggestion is to go buy a new/cheap set. Thanks folks!?

I need help with subwoofer box designs!!!

I've got this new alpine (well not new, but it still works) 12 inch subwoofer. The box it's in was probably alright for in the trunk of the car, but I'm planning on using it inside, as my sub just blew. Here's the size demensions of it: 15" wide, 16" high, and 13" deep. There's a hole about 3" x 2 1/4" in the back for the wire to come out. I was planning on using the internal amplifier from the blown subwoofer, in this box, but I need to cut a hole to fit the amplifier in. It sounds really punchy, but for a 200 watt subwoofer (that's rms) it doesn't shake my floor at all because it's basically a sealed box, the sub comes out the front, should I cut a hole in the front or side for a port? What if I used the pipe out of the blow subwoofer box, or is it specifically tuned for the 8" that was in there before? Thanks for any help.
