Amp going into protection

Try a different set of speakers or if it keeps going into protection you have a channel going bad.

It depends on how long you plan on running your amp when you listen to your music. If you like it loud for a long time, I would kep our speaker load at 2 ohms to keep your amp cooler. If its for car audio competitions where it wont play for so long, ! ohm would give you higher output but heat up your amp faster. Are the subs 2 ohms at each voice coil or 4 ohms? Bridge your voice coils together in parallel then bridge the 2 speakers together in series. That should work fine for you.

Hello lilcylentsur,

It sounds like when you connect both subs, the impedance match is too low for the amp to handle. 2 4-ohm DVC subs with both the coils and subs wired in parallel will present a 1-ohm load which is too low for most amps.

The solution is to wire the voice coils in series, (connect a short jumper from one positive to the other negative on each sub). and then wire the remaining terminals to your amp. This will result in a 4-ohm load which most amps can handle.

Here's a "wiring wizard" which allows you to see the ohm loads of different wiring configurations.

Hope this helps.

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.

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS

The specs I read on the Pioneer site say the amp is not 1 ohm stable, so keep that in mind.

It partially depends on the impedance of each voice coil on the DVC subs. If they are dual 4 ohm, and you connect the DVCs in parallel ("+"s together, "-"s together), you could run a sub on each channel of the amp(s). This would put about 200W on each sub.

The other option is to still tie the dual 4 ohm voice coils in parallel, tie 2 subs in series (one "+" to the other "-"), and bridge the two channels of the amp (aka put them in parallel). But this, also, would be about 200W on each sub.

Things get different if the subs have dual 2 ohm, 3 ohm, or 8 ohm voice coils.

you haave either connected it incorrectly.make sure the ohm of the speaker matches that of the amp ..connect the positive coil to the positive coil at the back of the sub and the same for negative .then run your cables to the amp .you should only have one positive cable and one negative cable .this connection will create a 2 ohm connection make sure the amp can handle that load .prefarably using a 2 channel bridgable amp or 1 channel monoblock

It sounds like you may have the load impedance too low. How many voice coils per woofer? How many ohms is each coil? If you have DVC woofers, are the coils for each woofer wired in series or parallel? Are the speakers wired in series or parallel. Let me know if you need me to clarify anything.
