Can i run my amp at 1ohm and how - Coustic Car Audio 321QE Car Audio Amplifier

Connecting the two 2 ohm speakers in parallel will create a 1 ohm load. Connect the positives of both speakers to the plus output of the amp, both negatives of the speakers to the minus output of the amp.

Do to the impedance Of your sub u can't run it @2ohms its going to either be @1ohm or 4ohms and your amp isn't 1ohm stable and u will risk damaging your amp. So your only option is to run it @4ohms and on a good note your sub is 100-600 watts RMS and your amp will push 400-500 watts RMS @4ohms. Now if you want to run 2 sub's in the future That amp will work perfect because it pushes 1,200watts RMS @2ohms and to wire your 2 sub's @1ohm just follow the steps in the image below. Hope this helped.

Wire as per the diagram:

you can run your amp at 1 ohm you would need to to have the right ohm subwoofer wired in parralle to get 1 ohm at amp ...... the put a 12 volt fan in the area to keep the amp cool so it doesnt over heat if you plane to

Run the amp in stero Run the 2ohm to one chanel, Wire the dvc 4ohm to run 2ohm + to + - to - to the other chanel and you should be fine.
If you had a 1ohm stable amp you could run both speakers wired 2ohm to a mono amp and have a 1ohm set up and double the power!

more than likely it will overheat at .5 ohm

Hello, your problem is that your amp is rated at 4 ohms bridged mono ans 2 ohms stereo. If your running it in stereo you need to raise the ohms to 2 ohms a channel and if your running it bridged into 1 channel you need to be running it at 4 ohms. Please rate this solution please so I can prgress on FixYa.com. Thanks!

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d

Hello ereza25,

The best way depends on what amp you are using to power the sub. With dual 2ohm voice coils, you can wire to either a 1ohm or a 4ohm final load. If you are sure that your amp is stable down to 1ohm, that wiring will provide the best power to the sub. But if the amp is not rated at 1ohm (many aren't), then the 1ohm wiring will result in overheating and possible damage to your amp.

The wiring diagrams are here. Hope this helps.

Hello jose08042008,

Your sub has dual 2ohm voice coils and can be wired to present a final load to the amplifier of either 1ohm or 4ohms. Unless you have an amp that is stable at 1ohm (not many are), then you will want to use the 4ohm wiring. To wire for 4ohms, jumper the positive terminal of one voice coil to the negative of the other terminal, and connect the remaining positive and negative terminals to your amp. If you know for SURE that your amp is stable at 1ohm, you can connect both positives and both negatives together on the sub and then to the amp. But if the amp 1ohm stable, this will result in overheating, and/or going into "protection" mode, and/or damage to the amp.

Hope this helps.

it all depends on the impendance of your subs if u have duel 4ohm or duel 2ohm, 2 duel 4ohm speakers can be wired at 1ohm to the amp, and with a kx1200.1 that would be pushin 2400 peak and 1200rms
if ya have 2 duel 2ohm speaker than you can only wire them to 2ohm and would be pushing 1200 peak and 600 rms with the kx1200, so if you have the duel 4ohm i would go with the kx1200.1 and if u have the duel 2ohm i would go with the hifoncs
