SOURCE: center channel speaker

Is the amp already used for L R? If so, you either need another amp for center, or set your Sony for stereo mix down. I have mixed the center channel into my main LR in the past and found there were terrible phase cancellations, so I suggest you switch to Stereo, or use a separate amp.

SOURCE: My audiosource 2 channel amp is dead in the left channel

Hi...
There's not alot of innerds on these amps.
They use a TDA7294 amplifier chip in the 50 WPC version and I have one here with both outputs gone bad.

The chip is cheap (<$10)

SOURCE: audiosource amp two intermittent distortion in monoblock mode

Good question, well constructed, a real fault report.

I would say from you fault description that maybe there is a dry joint / loose connection somewhere in the system.

So check all your wiring / connections.

Put the amp back into 2 ch mode and check each ch with the same source and load, do it both cold, and then drive the amp and do it hot do the shake test on both ch, cold and hot.

maybe this will help id the faulty area, if both ch have fault the it might be the psu as this is common to both sides.

If you can track down the fault to a or b then you can resolder all the connections on the board, if you are not happy with taking the lid off then take your amp with your test report to a tech, the test results may save you time and money.

Hope this helps, thanks for using FixYa.

SOURCE: I have 3 Audiosource Amp-100 that have failed out

When the fuse keeps blowing you have an overload. The cause of which is either in the power supply or the main amp. It will almost for certain be a semi-conductor of some type acting like a piece of wire. A multi meter will show up a most faulty parts with this condition. On the Ohm setting applying the test probes to transistor terminals (E,C,B) you will get a responce like you had touch the probes together! The power transistors or whatever is on the heatsink are good at going short circuit, as people often short the speaker wires together.
Don't forget to check for burnt or damaged parts too.

As a rule of thumb with transistors when testing on a meter (1K setting) (best with moving coil scale meter than a digital) apply to base (B) and then to C & E you should get an ohms reading. If you don't get any reading (both ways) it's dead (open) and if the meter goes full scale - it's shorted.

How loud do you expect it to be?

More watts doesn't mean more loud but it gives you more headroom for cleaner reproduction of very loud passages. Distortion will kill a speaker faster than clean signals will.

I have to hook up 4 amps in my car. 4 channel 700 watt ken wood, 2 channel 800 watt Sony, 4 channel 740 watt Jensen ,and a 2 channel Rockford fosgate. Which is best way to hook them up so I'm not ki


Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,

This will create a 4 ohm load on your amp.

Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.

I have 2 10" Kicker Comp Subs


That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

How can you bridge a 2 channel 300 watt amp to a 4 channel 300 watt car amp?


if you have (4) 4 ohm speakers (No Subs), then you simply take the (2) positives from the two right speakers, and the (2) negatives together and put them on the right output of the amp. Do the same for the other side. This will have the amp at a 2 ohm stereo load on each side, which will max out the power of the amp. Will sound great with any small power amp.

How can i bridge a mtx 9500 using a mono amp?


You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

2 MTX Thunder Problem.. Bridging?


Is there a option on the chanels that say ''Bridged''? If so, you can hook the subs up in parellel or series to get different ohm loads. Usually the lower ohms, the more power amp puts out. Those subs can handle 225 watts RMS whitch means the power it can handle constantly. If the amp gives more than 225 watts RMs, you could be at risk of blowing the sub. If you could give me the model # of the amp, I can be of more help.

8 ohm to 4 ohm


All you need to do is wire your 2 subs together in parallel. This means Hooking the positives of both subs together, as well as hooking both negatives together.

Your total resistance:

Rt = (R1 x R2) / (R1 + R2) = (8 x 8) / (8+8) = 4

A ---------------- + ------------ +
