I have power akoustik 12"

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

you need to wire each sub down to 2ohms then wire them together like the one in this pic http://m.seimg.net/product/img/subwoofer_wiring/2_subs_DVC_4_ohm_mono_variation2.jpg witch will give you 1ohm so you will be getting every bit of power that amp has but you should get a bigger amp for thos speakers

You have a case of a blown sub. You will need a recone kit. You ca send it in to a company like fix my speaker or google recone kits for Power Acoustik FUBAR. May be cheaper just to get another sub.

Hello chino2g,

For 3 DVC 4 ohm subs wired to a 2 ohm stable amp, your best option would be to wire all of the sub voice coils in series (individual 8 ohm loads) and then parallel the three subs for a final load of 2.67 ohms. There's really no other configuration. Here's the wiring diagram:

Hope this helps.

personally i wouldnt use a sony amp for powering anything but,however if your going run it what i would recommend is if the speakers are at 4 ohms then run in series per speaker then put the speakers in series as well so you will keep your 4 ohms then run the amp in mono,however just to let you know that amp will not push fubars enough to really make them thump my advice is to goto http://www.sonicelectronix.com  if you have 200 dollars you can get a nice  Hifonics TXi 1508D that will push those monsters quite well thats 1 ohm stable and will barley get warm even after hours of thumpage,also if your running subs monoblocks are the way to go hope this helps you out.

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

well it is getting hot due to the amp drawing and pushing alot of current. try getting lower gage wiring for power to the amp and lower gage speaker wire.

you Amp is overloading and going into protection mode. if it cuts out with the wire u were using first then their would be no need to upgrade the size of ur wire cause that would only be, doubling or trippling the power u are getting threw those wire now. bottom line the 2 subs u are using are obviously to much for the amp. try dropping the OHM's by connection the subs together and runnig just a single positive and negative to the amp! or just get a better amp

For each sub, tie the DVCs in parallel ("+"s together, then "-"s together). This will make the subs look like 2 ohms to the amp. Then, put one sub on each channel of the amp. That will put about 280W rms onto each sub, the max for the amp.

If the display goes out then it is possible the flex cable is broken. Return it to Rockford for repairs.
