AudioBahn A4002T Car Audio Amplifier - Answered Questions & Fixed issues

It would make sense that if your radio turns off, your amp will shut off too since its likely your amps remoae power signal is delivered via the light-blue wire from your radio.

so the question is, why is your radio shutting off.

Odds are your using an aftermarket radio and your ground wire is poorly connected.

check it.

More than likely the amps internal relay that is powered by the remote lead has shorted open, allowing the amp to connect power and ground regardless of the remote signal.

Should be a relatively inexpensive fix at an electronics repair shop.

audiobahn went out of busnes 5-8 years ago i wold replace the amp with a class d diferant brand

That usually happens when your amp keeps clipping and basically doesn't have enough juice to push the speakers. You can try to ground the amp better, preferably to the chassis, and you can also get a capacitor and see if that helps keep the steady power going to it. There are those times that the amp is just getting old, but I would try these simple solutions first. Hope this helps.

Have you changed the speakers? Usualy an overheating amp means the resitance on the speakers is too low. If your amp is only 4 ohm stable, and you have two 4 ohm speakers hooked together, you are running a 2 ohm load. Hope this helps.

It Could be Eiher Problem Make Sure The Remote our using is thew same brand as the amp its plugged in to

Does it blow them immediately when inserted, only after the headf unit is turned on or only at high volume?

You have to wire it in 'Bridge Mode'. https://www.google.com/search?q=audiobahn+a2301Q+connect+2+subs%2C+2+speakers

The amplifier is only stable to 2 ohms.
Assuming the cubs are dual 4 ohm voicecoils - a 2 ohm load with 2 subs is not possible.
You can only wire up 1 dual 4 ohm voicecoil sub (both positives to amp... and both negatives to amp) to get a 2 ohm mono load.

Hello William Novelli, if it would be compatible, but you should control the order of the connections, they can vary I send you the link to download the manuals of both models and compare the connections, if you find it complex, consult a specialized technical service I hope you find it useful Regards Franco Dosil Hola William Novelli, si seria compatible, pero deberas controlar el orden de las conexiones, pueden variar Te envio el link paravque descargues los manuales de ambos modelos y compares los conexionados, si te resulta complejo, consulta con un servicio tecnico especializado Espero te resulte util Saludos Franco Dosil https://manualmachine.com/audiobahn/aeq7/18414-user-manual/ https://manualmachine.com/audiobahn/aeq8/18268-user-manual/ https://www.manualslib.com/manual/211695/Audiobahn-Aeq6q.html

as your sub is only rated to 400w rms simply connect the sub to either a or b channel outputs you may wish to use an rca splitter before the amp to feed both left and right audio channels into a single channel on the amp. WARNING connecting both channels on the amp to the sub will overload the sub and possibly blow it up so i highly recommend not doing so.

i was not able to locate a manual but i did find some interesting information that hopefully may help, The AudioBahn AW1000X Car Subwoofer Features: dual 4-ohm voice coils, non-pressed pulp cone, huge foam surround, frequency response 23-500 Hz, power range 50-600 watts RMS (300 watts per coil), peak power handling 1,200 watts, sensitivity 91.1 dB, top-mount depth 5-1/4" ,sealed box volume: 0.4-.95 cubic feet, ported box volume: 1.632 cubic feet.

i'd need more info but from what you've stated, sorry to break it to you but it sounds likely you've incorrectly wired you speakers and blown your amp. this will prove no doubt an expensive mistake and learning exercise.

to drop the amp load to 1 ohm you need to divide the output signal path and the best way is by wiring a second woofer in parallel as seen in the ideal diagram attached this has the desired effect of doubling the volume . since 2 ohm divided by 2 is 1 ohm load connected to your amp. so the short answer is no you can't do that with a single woofer

Generally there are 2 parts to this problem part 1 input signal as these woofers are just subs remember to give them a low line in signal before the amp (see diagram) i like to use rca low pass crossover filters from harrison labs (see link) part 2 is the wiring configuration of the 2 woofers by wiring them in parallel as shown in the diagram you reduce them to a 2 ohm load for your 2 ohm amp meaning you'll get max loudness and efficiency Harrison Labs FMOD Inline Crossover Pair 100 Hz Low Pass RCA Shipping is...

unfortunately if you only have the one woofer there isn't really any safe way to do so but if you had a pair of woofers you could in theory wire them in parallel thus creating only a 3 ohm load but your amp must be able to work at such low ohms otherwise you WILL blow up your amp.

First, what type capacitor is it? If it looks like a small can, then this will be a polarized canister type. There should be a small band on one side with arrows and probable plus marks. The wire below the can on this side will be the positive side of the cap. Make sure you note where and how you remove it from the circuit as a new one will have to go back in the same order. Look on the side of the can, you should see a number followed with a figure that looks like a 'u' with a line on both sides. This will mean microfared. Which is a unit of measure. (Example. 1000 u ) would mean one thousand microfared. (Micro is a measure for parts of a million). Now note the physical size. Very important since this determines the power handling capability. Do not reinstall a new part that is different. Now you are on your way to a complete repair. Take the old part and try to find a local electronic parts store. You can usually buy an entire pack of these for a few bucks. You can also search online. You may also use a cap of the same type from an old circuit board if one is available. NOW IF THE CAP IS A SMALL CERRAMIC TYPE, this one will look like a small round disk, usually light brown in color. This one can be reinstalled in either direction. It is not polarized. There should be a number on one side, (example: 1000 u) .the size also matters just like the can type. Replace with identical type. If no number is present, take the part to your local electronics store. (Radio Shack for example). If this fails, I would go on line and find the manufacture of the product. You may also search REPAIRCLINIC.COM they carry a large line of parts. Hope this helps.

There are several facebook pages. Old school stereo for sale, i was into auto sound in the 80s and 90s, legends of car audio. Otherwise watch for one to come up on ebay.
