Problems with Infinity Amp 611A

I recently installed two 12 inch rockford he fosgates and the infinity 611-a amplifier. When i was finishing up wiring my deck and got ready to connect the remote wire i could not get steady power to the amp. The lights "clip" and protect" light up when we play with the ground, but cannot get thw power LEd light to come on or stay on. Just wondering if anyone has any comments or answers. The led lights clip and protect only come on when we play iwth the ground which makes me think maybe thats it, however i have removed and remounted the ground three times, and wont give me ANY power, not even a quick flash when the ground is completely secure, but flashes when the ground sparks at a new source.

    I had a similar problem-- my 611a had its protect and and clip lights on, but now has nothing. I've tested my remote, power, and RCA's, and they all read the voltages they should. The ground is also fine, as I've had an amp that worked before connected to the same point. My fuses are all good, and I've tried with and without my capacitor. My sub has been tested with another amp and works fine. Any other ideas to test it?

Are you running a large ground wire directly to the battery negative terminal?

I had the same problem, and it turned out to be a problem with my subs. I would check them.

Need to know how to wire my system ...I have the infinity reference series 611a I was told it was a mono block but it has two channels on the exterrior...also I have two 12 inch MTX thunder dual voice coil...


it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.

I have a four channel rockfor fosgate amp and I need to know hows the best way to connect Infinity Reference 1252w Car Subwoofers


Rockford fosgate usually work best with 2 ohm speakers. Depending on the resistance of your speakers, will then give you best connection. Check the resistance for the subwoofers. If the subwoofers are two ohm then connect them directly right and left. But if they are 4 ohm connect them parrallel (positive to postive, negative to negative and bridge the amp.) Good Luck, please rate.

Infinity 336rms amp worked for over a year then one day stopped?


check your fuses. Also check the power wire connection to the amp and then the ground source maybe move that if there is paint under it. check fuses on the amp. Check ohm load to the amp from the speakers.

Component speaker not working


The easiest thing to test is to try swapping the connections of the front component speakers at the amp connections. If the problem follows the speakers, the issue is probably with the speakers. I would triple check (again) the speaker wire connections. It's also possible the crossover for the driver side component speakers has an issue (thus why the tweeter worked for a while).

If the problem stays on the drivers side, the issue is probably with that channel on the amp. Triple check the RCA connections for that channel.

It's much easier to test other speakers on an amp channel versus trying to check it with a meter.

If the driver's door is "abused" often, my initial thought is the wiring at the speaker or the wiring in the speaker (to voice coil, within the crossover, etc) is the most likely culprit.

Trying to wire my amp to my subs


no thats not it you are lucky you havent burned it up like that. wire each speaker to its own source positive and negative, you loose power when you bridge an amp and use two speakers, its best to hook up without bridging you will get more volume that way.
