If you use RB1 (shunt resistor) of 1 Ohm you can measure up to 200mA AC. Read scaling part in attached document.

Got 2 woofers, 2ohm stable each. If I get 1ohm stable monoblock amp, will it split that 1ohm equally in 2ohms for each speaker, or would I have to buy another 2 speakers that r 1ohm stable each?


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.

I have 2 12 inch kicker rt dual 2 ohm subs. On a kicker cx1200.1 i want to kno how to hook it up to 2ohm to the amp. And if i can add another 10 inch kicker rt 2ohm sub in the future.


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.25345194-v0hbouy2nvquqteoroa5j5rq-3-0.png

How do i get the most watts possible from this amp, with out overheating the amp.


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

I have an alpine type r how do i connect it i have all amp an everything hoked up but i dont know how to connect the sub since it has 2 red and 2 black


On just the speaker itself, hook up a short wire going from red to red, then hook up another short wire going from black to black... Then put one wire in either black slot and one wire in either red slot to wire to your box.... That is the easiest way... But if you are interested in other methods I will post a link... How you wire will change the OHMS, so depending on what model sub you have and what amp you have, going to 1ohm may not be safe for your amp if your amp is NOT 1ohm stable.

Why does the hifonics bxi1608d 1600 watt super D-class mono have 2 postive terminals and two negative terminals? would that cause my speakers to blow?


That is still a single channel cass D amp. Each (-) and each (+) terminal are connected so its actually like only having one. This is so you can hook speakers up in a series circuit to lower impedance, because this amp is 1ohm stable. What causes your speakers to blow is too much power. What kind of speakers are you running? This hifonics amp is very powerful, they are getting big in the competition industries beacuse they put our true power for less money and they are tough. That 1600 amp you have may be putting out more like 1800 watts at 14.4 volts which is 900 per sub at 1ohm so be careful this amp has tons of power and its true rated its not like a sony or rocksford or kenwood that says 1800 max and then in small writing it says 500 rms. This amp puts out true. I have 3 hifonics amps and love them.

Whats the best way to hook up my L7 10''


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.

Wiring hk12x2


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.

I want to hook up my 2 quad coil woofers to a 1ohm amp but


I would look up "series" and "parallel" wiring on the net. Parallel will lower your ohms, which is good- especially for you since your amp is 1ohm. use 1 channel of your amp (unbridged...bridging an amp could increase output, but will Raise the ohms) connect the positive terminal with a wire that goes to the positive on your first sub, and from there, connect a wire from that same positive terminal to the positive terminal on your second sub. do the same thing with the neg. wire. This is called parallel wiring.
