Diamond Audio Amp 1200.1 D5 Blows Fuses When Connected to Power!

I just got a used Diamond audio 1200.1 to power my Diamond D6s. I had the system working for about 3 weeks and it was the loudest system I've ever heard. One day, I disconnected it to test my other amp and then re-connected the diamond and it blew the fuses instantly because I never disconnected my battery. Now I purchased new fuses to use and it automatically blows them when power is connected. I don't want to have to buy a new amp. What should I do? I already took it apart and can't see any visible problems. Any suggestions? Any suggestions? Anyone having same problem with other amps? Anyone know where to get a new 1200.1 board to replace it? Please help!!!

If there was a misconnection polarity, you coud check fo shorted diode at power entrance circuit.

Whats the best way to hook up 2-10'' 4 ohm dual voice coil to the d5 1200.1 amp

4x4 ohm voice coils can be configured to either run @ 1 ohm, 4 ohm or 16 ohm, while the amp needs to be dropped to 2 ohms, no lower, to be most efficient. if a single dvc sup could handle 1200 watts, then hjust run 1, with both coils positive and negative inputs connected to the amps output. if you needed both subs, you would lilely only get 600 watts, by creating a 4 ohm load by running both speakers to the amp positive to 1 ccoil, each speaker, an mjumper cable between the negative of 1sdt clils to positive of 2nd coins, and running both 2nd coil negatives back from both speakers to the amp negative. the 2nd wscenerio will result in less sheer wattwage, but will also provide cleaner power. you need to study ohms law and parallel versus serial wiring to accomplish the 2nd scenerio, or, just get 2 4 ohm single voice coil speakers that can handle 600 watts apiece.

Amp constantly blows fuses as soon as power wire is connected. anyway to fix?

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty .
.A thumbs up would be greatly appreciated if this answer is helpful to you

Just bought 2 12 in d3 dual 2 ohm subs with d5 600.4 amp. Need to know how to wire subs. They were in a box already I assumed they were wire at 2 o When i hooked One up to my amp it hit really for Jus...

what wattage are the subs and amp? if your subs are more wattage than your amp, your amp will blow fuses as cant handle the output to your subs. for example. you have 2 500 watt subs and a 300 watt amp, that is no good as amp isnt powerful enough. if you have 2 500 watt subs you need at least a 1200 watt amp to power them both. 200 watt more than the combined wattage of subs as amps should never be turned up to max as they tend to blow and overheat more quickly. 80% volume on amps is reccomended by installers and manufactures.

Kenwood KAC-729S keeps blowing fuses. Checked all cables, re-ran power, remote, and ground. All good, still blows them at power-up.

Hello opey_69a,

Here are the troubleshooting steps for fuses blowing.
1) Remove all wiring except ground, power and remote and see if the amp powers up without blowing the fuses. If it does, the problem is in the input cables or speaker wiring.
2) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current - check.
3) A shorted or grounded RCA cable may cause the fuses to blow - check.
4) If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier is probably defective, most likely shorted output MOSFET's. In this case the amp needs professional repair or replacement.

Hope this helps.

Power fuse on amplifier blows as soon as the power cable is connected

you should check the fuses your using may be too small and make sure you connect the positive first then the ground cable and there are no shorts when you ground the amp.

the most common will be the fuse ampage is too low thats why its blowing when you power the amp

Hooking up system to a factory infinity sound system in a jeep grand cherokee.

Tap into a signal wire (rear speaker wire) using a line level converter.
These convert the High level speaker wire output into low level RCA output that is accepted by your amplifier.
c5b61ef.jpg Get a good one Pacific Accessory Corporation (PAC) sni-35 is the best IMO.
The TRUNK-LOC is the SAME as the SNI-35 - but it incorporates a voltage sensing input - so you dont need to run an additional turn-on wire. The voltage is sensed through the speaker wire - and it turns on the amplifier.

Then you will need a fused power wire from the battery,
Ground to chassis, and remote turn on lead (if you use a standard line level adapter).

An amplifier installation kit will give you everything you need to add 1 amplifier (except the converter)

Fuses blowing

It may not be your amp at all, disconnect the power wire from the amp and then try a new fuse. If it still blows you have the power wire grounding out somewhere, if it doesn't then it would have to be the amp.
