AMP Gains???????

[hussnainh8]

Hi,

I have a AMP and Sub woofer and the Gains are not set up on the AMP.. These are connected to my computer using a car battery. I would like to know if the Bass Boost knob is supposed to be set to half or max? I cannot set the Bass Boost to 0 BECAUSE no matter how high I set the Gain I will not get any sound out of the Sub woofer so I either put the Knob on half or max.

Is there any way to check my Sub woofer OHMS? I tried and all I got from the Multi Meter it said "066"

What I can say is, the lower the bass boost is, the better.

Oh boy, here goes nothin'.

If you don't know your subwoofer's impedance, totally unhook it from the current amplifier. Then, put one lead of your meter on each of the terminals - positive to positive, negative to negative. Make sure you're just reading ohms. Power has nothing to do with impedance, I think you might be misinformed.

Now, to address the bass boost problem - don't use it. For now, you shouldn't even have anything hooked up if you don't know what impedance you're playing at. That's a good way to wreck gear.

Find out what coils are in your subs and we'll be able to help you from there. But until then, we can't really recommend an amp, or even know whether or not yours is stable where you're wired at.

ignore this!

I cant just choose OHMS..The Multi Meter has 5 settings, 2000K,200K,20K,2000,200

How can you say not to use the Bass Boost because if I don't use the Bass Boost I do not get any sound from the sub woofer.. When setting the Gain I played a tone at 60hz and set the gain to 20V assuming my speaker was a 1 OHM. How do I find out the coils of my sub? I'm not experienced with opening speakers up to find coils etc..??

Why do you say its better when the Bass Boost is set lower?? When the Bass Boost is set lower the Sub barely gives out any bass regardless of what the Gain is set too?? I gave another check for the OHM's and this time on my Multi Meter I changed the setting to "OHMS - 2000" and the Multi Meter reads 004 ..

Because the very fact that you have to use bass boost to 'get any sound' from the driver is an obvious indicator that something is wrong. I mean, is that not obvious? Bass boost eats up amplifier power and causes distortion, neither of which you want. If you can't figure out what impedance you're running at, you'd be best off unhooking everything before something gets fried. You could be running at too low of an impedance, (which will hurt your amp) or too high (which would explain your lack of sound). In either case, something's not wired right, and you need to get that figured out before being able to fix anything else.

So something is not wired right? The only thing I could guess might not be wired right is the Sub woofer wires to the AMP? I can take a picture of the wiring if that makes it easier for you? By looking at the picture maybe you can tell me what is not connected up right?

Right. Is the sub a dual or single voice coil driver? How many terminals are there?

Your impedance is determined by how your sub is wired to your amp. For example, a DVC 2 ohm sub could be wired to 1 or 4 ohms, it just depends how it's wired.

A picture would work well, especially with readings on the meter. That'll help us interpret what you're looking at.

I don't know if its single or dual it doesn't say on the Speaker.. It has 2 terminals 1 Red and 1 Black..

Here are some pictures of the readings and the AMP wiring..

with those readings theres should be something wrong. Bass boost most of the time only adds distortion.

I have no choice other than to set the Bass Boost either at half or full however I do not get any distortion from the sub woofer itself even when the Bass Boost is set to full! Maybe the reason to that is the Gain is set lower than what it is meant to be on but I cant set the Gain while these readings are giving weird results //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif ..If the Bass Boost is on 0 and the Gain is Full I still do not get any sound from the Sub woofer the Bass Boost must be set higher than 0 for any sound to come out the sub.. totally confused //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Okay, that means it'd be a single voice coil sub. The readings don't make much sense to me, either...something could already be awry. If you're looking for a good sounding, long-term application, I think you should consider getting some new, quality equipment. Do you know what amp/sub you're using?

The wiring kit I am using is already of good quality, I made sure to purchase good quality wiring to hook all the setup up. The AMP is a Tornado I-AMPM202 400 Watt 2channel (bridgeable) with built in treble/bass and the Sub woofer all I know is its a NEXT 350 Watt Speaker. and yes i am also guessing its a single coil. The subwoofer gives out clear sound and I know 100% it is not blown etc. I can get awesome sound out of it when setting the Bass Boost on Max and the Gain about quarter way up it shakes the whole house but I do not want to keep it on there because I dont want anything to blow up. That is why I want to set the gain etc but cant without knowing the OHMS //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Are you running the amp directly from the PC? Are the RCA's from the amp hooked into the PC? If that's the case then that's likely the problem.
