No power my amp will come on but it is not producing any power. my first one pounded, but my friend tried to wire it to 1ohm it amp quit working. so today (aug. 10 2008) i bought a brand new vibe286 and is powering the same speakers. it comes on but speakers sound like my regular 6x9s. i have 2 12" ma audio subs. it is not pounding like my previous vibe286. i had my bass controls almost all the way down with first amp, this one all theway up and hardly anything. i also have a cap and deep cycle batt.

Are your subwoofers wired in series or parallel? Check your connections, if everything is ok, the problem is with your amplifier. It might have a blown capacitor inside or its not really a 1ohm stable amplifier. Have it repaired if thats the case.

Wire as per the diagram:

more than likely it will overheat at .5 ohm

Hello rigo11785,

The MTX Thunder 1501D is stable at 1ohm and outputs 1,500 watts RMS into that impedance. An L7 with 2ohm DVC's would present a 1ohm load if wired in parallel and would allow the amp to produce more power than into the 4ohm series load. The problem is that the L7's maximum power handling rating is only 1,000 watts RMS, so if you wire the coils in parallel, you'll very likely overdrive the sub and perhaps damage it. Now, if you bought another L7 and ran the voice coils in series and the subs in parallel, that would be a 2ohm load and well within their power handling capability.

With that amp and sub, I'd recommend leaving the voice coils in series.

Hope this helps.

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.

Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

Hello rcantu76,

If your CVR's are 2ohm (model Nr. 07CVR122), you connect the voice coils in series and then parallel both subs to the amp. If the subs are 4ohm (model Nr. 07CVR122), they cannot be wired to 2ohms. Your choices are 1ohm or 4ohms. According to Rockford-Fosgate's data on the P1000-1bd, it is stable at 1ohm.

To wire the 122's at 2ohms, you would connect the sub voice coils in series (jumper one positive to the other negative on each sub), and then connect the remaining positives and negatives to the amp.

To wire the 124's at 1ohm, you would connect all of the positives and all of the negatives together 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

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.
