Question about AudioBahn A1300HCT Car Audio Amplifier

1 Answer

No sound out of subs

I have an audiobahn a1300hct amp with 2 infinity kappa perfect 10" subs hooked up in a 2 ohm load. My HU is a pioneer 8500. My problem is when I turn on my HU i hear a pop from my subs and that is it. This happened once before and after a couple of days the amp started working fine again. I've tried everything I changed my fuses re did my ground cable which is now 2 gauge and I'm running a 4 gauge power cable. This didn't solve my problem. still no out put. I checked the rca cables and i did get a signal out of them i tested them with a DVOM. Remote power wire is also good. I don't want it to be the amp but I fear that it is. Any help at all would be greatly appreciated!

Re: no sound out of subs

Check the ohm of your soeakers again. If it doesn't say 2 ohm thats the prob. Keep in mind that 2 ohm can be any where from 1.7 too 2.3 but any reading on you DVOM that gives you two decimal places is also wrong. i.e. 2.17. This would mean that you have a woofer shorted.

If thats not it and you have already fixd a ground then use your meter to check the ground; to do this set the DVOM to ohms and touch one lead to a true gound, by that I mean scratch the paint and primer off of a spot you can hide untill you see bright mirror like metal. Then disconnect the ground wire from the amp and touch the other lead to it. You should read anything from 0.3 to 0.1 any higher and your ground isn't that great.

If thats not it, The only thing left is to hook the amp up out side of the vehicle away and not connected to ANYTHING that has to do with the car. Get a battery and a diskman or a playstation, anything that can pass sound out of RCA's (Maybe even a diff radio if poss). Hook it up. If it works its in the car and let me know. I'll tell you some more to check, If not its the amp. Good Luck

What may of happened if that you got the lacquer finish on the electromagnetic wire to heat up and come apart. At low volume they will still have an electric connection. Because the wire physically came off from the inner housing of the voice coil it is in contact with the side wall of the speaker magnet and is proned to causing a short between coil sets. Your probably running subs with a 4 ohm impedance and when your coils short it acts more like a 2 or 1 ohm speaker. This is similar to whats called a dead short. Since the Independence is dropped to 2 or 1 ohm it is the resistance equivalent of having 2 or 4 subs attached to your amplifier which caused the final transistor bridge to heat up and it can get hot almost instantly. Check your amps outputs individually on a single speaker that you know works perfectly. If your amp does not trip the thermal protection you most likely cooked a speaker beyond usable condition.

yor subs have dual 6 ohm voice coils from the sound of it-your amp is rated at 650 watts rms at a 1ohm load. The best you can do with the equipment you have is to wire ALL the coils of your subs in parallel and that will give you a 1.5 ohm load for the amp.It should knock the hell outta them with 300 watts on each sub - good luck

Infinity 1211a @ 2 Ohms

Hello monkey_flea, Your subs will share the amp output. And if you are not careful, you'll end up blowing them. The amp puts out 1300 watts RMS at 2ohms, the subs have an RMS power range of from 75-350 watts, and you'll be driving them with 650 watts each. A better power match would be to series the subs to present an 8ohm final load. This will reduce the output power to a level the subs can handle. Or you could buy 2 more 12.1's and connect them series-parallel for a 4ohm load and each sub would still be getting 325 watts RMS, just about the maximum they are rated to handle. Hope this helps.

i recomend you just use the best single woofer in a well built box and that will give you better sound at lower gain volumes it sounds like you have too much junk laying around but to get good bass run your sub at 2 ohms if the amp is stable at that impedence

Amp. Audiobahn a2300hcx

If the subs are dual 4 ohm voice coils and if your amp is good down to 1 ohm, your best bet is:
  1. Connect the voice coils in parallel ("+"s together, "-"s together). This will make the impedance of each sub 2 ohms.
  2. Connect the subs in parallel.
  3. Bridge the amp to one channel.
This should max the amp out at 2400W, which means about 1200W per sub.

If your subs are single 4 ohm voice coils, do the same steps, but you'll only be able to load the amp to 2 ohms, which means about 600W per sub.

Also keep in mind that box size, type, and quality make a big difference in how subs sound.

Pioneer prsx720 wiring question

If the subs are dual 4 ohm voice coils, you could hook the DVC's of each sub in parallel ("+"'s together, "-"'s together) making each sub essentially 2 ohms. Then connect one sub to each channel of the amps. This will put about 200W on each sub.

Tryin to hook up 3 10

The Class D amps from JL are good down to 1.5ohm. The class A/B amps are good down to 2ohm.
I take it you have (3) 4 ohm subs? Wired in parallel?
Consider looking for an amp that is 1 ohm stable for this load such as audiobahn, or kicker.
