Some amps very in what will happen first, some will blow the fuse and some may go in protection mode or the sound will come and go.

Can someone please show me how to wire my subs to amp.. i have a 2600 watt planet audio 2 channel amp (2 ohm stable) and my subs are soundstream tarantulas t4 12s 900/1800 watts total. they are 1 ohm subs...


for your subs and amp the best way would be for the speakers to be wired in series1ch (mono or bridged)to have a 4 ohm load to your amp stable at 2 ohms
see pic for wiring diagram for 2 1 ohm dvc subs wired in series.
you will need more than one speaker wire for wiring the subwoofers coils(positive & negative terminals) together
hope this helps :~)

It keeps blowing a fuse


Generally, if you are using the manufactures fuse rating you can use a slightly higher rating and it will resolve the blowing fuses. Fuses supply resistance, if there isn't enough resistance you'll fry the system board in the amplifier. But if you have 25 amp fuses installed, install 30 amp, if you have 30 install 35 amp, 35 install 40. Anything higher will damage the amp.

Hope this helps.

A rare chance, something may be internally wrong with the amp and shorting it out which will blow the fuse.

Use the incorrect wiring of subs to the amp, you'll blow fuses and damage the amp from it turning off consistently. The amp should be running at 2 ohm stereo stable or 4 ohm mono stable.

Very few amps are designed to run at 1 ohm or less. Not to mention the subs can't handle it.

What do you do when your amp keeps blowing fuses


First off which fuse is it? The inline fuse from the battery or the amplifiers power supply fuse? Blowing the main fuse from the battery is caused by either the load (your amp) drawing too much current or you have a short to ground somewhere. Maybe there is a tear in the 12Vdc line and it is shorting to the chassis of your car. If the amps power supply fuse is blowing as soon as it turns on your amp has a shorted power supply. This will require internal component changes by a technician. If it is blowing after operation at high volumes I would say change the impedance that the amp is driving. If you are at 2 ohm try to rewire your speakers for four ohm. (go from parallel to series wiring then bridge mono or operate the amp in stereo mode)

2 12" dvc subs 2 ohm stable amp


+ on amp output to + on speaker #1 to + on speaker #2. - on amp output to - on speaker #1 to - on speaker #2. This is a parallel circuit....4 ohms in parallel with 4 ohms = 2 ohms. IF it were wired in series....would represent 8 ohm load.

I have 2 dvc 4 ohm alpine type r 15's and 2 svc american bass


Hi mate very nice amp you got there here is the specs for it



Model: MA Audio HK401SX
Hard Kore Series 1800 Watt 1 Channel High Performance Class X Car Amplifier
1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS @ 1 Ohm Mono
1 x 650W RMS @ 2 Ohm Mono
1 x 500W RMS @ 4 Ohm Mono
Fully Unregulated MOSFET Power Supply
2 Ohm Stable @ Mono
1 Ohm Stable @ Mono
0.5 Ohm Stable @ Mono

if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck

2 alpine type r 15's 4 ohm dvc and 2 american bass svc 4 ohm and hk401sx how do i get the most beat?



Option 1 (parallel) = 0.5 ohm load
Voice coils wired in parallel
Recommended Amplifier: Stable at 1/2 ohm mono This set up will blow your mind as your amp will put out 1800rms at 0.5 ohm

Sub Wiring


Hello jtkpay,

Rockford-Fosgate claims their latest V-power 1500bd is stable to 1 ohm, and I would think that your Oldschool would also be. The 2 wiring options for 3 subs with 2 ohm dvc would give you a 1.34 ohm load and a 3 ohm load. The 1.34 ohm option would mean more watts to the subs, but the amp will run hotter. The diagrams look like this:

Using just 2 of the Kickers, you can wire 3 different ways, with final impedances of 0.5 ohms, 2 ohms, or 8 ohms. You do not want the 0.5 ohm load. It's bad for the amp. You don't want the 8 ohm load. It doesn't allow the amp to produce as much power. So that leaves only the 2 ohm, with coils in series and subs in parallel. It looks like this:

Hope this helps. If it does, please rate as "FixYa".

Wiring options for amp


Te dual inputsm are tied together on the output side thus having a "MONO" amp. Most class D anps are stable down to 1 ohm (check your manuel) therefore, 2 2ohm subs are a 1 ohm load. 2 DVC (dual voice coil) 4 Ohm on each voice coil will give each sub a 2 ohm load so 2 dual4 ohm V's will give you a 1 ohm load as well. Parrallel all conections.

What subs do you have? Is this amp 1 ohm ono stable?

How do you make two dvc subs run at one ohm and put them to a 2 ohm mono block


Make sure your amp is one ohm stable. If you wire the subs at one ohm and the amp is not a one ohm stable you run the risk of blowing the amp if not both the amp and the subs

Speaker connections


This is a single channel amp that puts out about the same power at 4 Ohms or 2 Ohms. If you have two 4 Ohm single voice coil subs, then wire them parallel (both pos and both neg) to achieve 2 ohms. If you have two dual 4 Ohm voive coils, you want to do a series - parallel config to get to 4 Ohms (voice coils in series, then parallel the subs). Same with DVC 2 Ohm subs, series parallel = 2 Ohms. Do NOT go below two Ohms. You will blow the amp (actually, it'll do 1.5 Ohms). If you happen to have 2 Ohm single voice coil subs (not as likely) run them in series. Most amps will put out about twice as much power at 2 Ohms vs. 4, but this amp is designed to put out about the same. Hope this helps!
