What amp is it? you have no specs listed or model number. Look online or go to the manufacturers home page

What is the actual watts per channel @ 8-ohms and 4-ohms on the Behringer PMP3000?


Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board. This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side. You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine. For the record.....you could run one speaker per side no problem....just lower power output.

Hi, I want to know what is the best way to wire these subs. (Pair). I have heard of several ways. I have a 4 channel amp the soundstream picasso 4.760. Bridged it produces the most power. I was told...


Hello , I will be glad to help you.As far as your speakers..It depends on what impedance your subs are rated and if your Picasso amp can be bridged at 4ohm or 8ohm. If your subs are 8ohm each you can wire your subs in parallel and wire them to picasso amp in bridged mode. If your subs are 4ohm each.Then wire the subs in series then wire them to amp in bridged mode..caution do not wire subs in parallel if they are 4ohm .This would bring impedance to about 2 ohms and would be harsh for amp to handle...Goodluck

My speaker just rip.. i like to know any subwoofer is ok for replace??


it's an 8 ohm driver. It need to be VERY efficient, around 90-91db @ 1w. Measure the enclosure size LxWxH then divide by 1728. That will give you your cu. ft. internal airspace of the box. Then look for a driver that will effectively work in that space. Shouldn't be too expensive, paper cone, foam surround, 8ohm impedance. Hope this helps

Whats the rateing on the polk 10 inch sub woofer


Hello dread2477,

The Polk Audio db1040 is a single voice coil 4ohm subwoofer. The db1040DVC is dual voice coil with 4ohm coils which can be wired in parallel for a 2ohm load, or in series for an 8ohm load. They are practically the same sub. The RMS power range is 50-270 watts, with a maximum peak power of 540 watts.

The full specifications including recommended enclosures and physical dimensions can be found here.

Hope this helps.

Finding the best amplifier


Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

I have a 50x2 amp that is bridged 100 into a 4 ohm load. can i run this to a 6x9 3way speaker rated 100rms 4 ohm


Yes, you can. There's the impedance match between amp and speaker (4ohm to 4ohm).
The only issue I would say is that if the amp is putting out 100 watts RMS, then you wouldn't want to drive the speaker to the max, because it's rated at 100 watts RMS max, and at louder volume, it will start to distort and possibly blow from fatigue. Other than that issue, it should work fine.

Infinity 1211a @ 2 Ohms


Hello monkey_flea, Your subs will share the amp output. And if you are not careful, you'll end up blowing them. The amp puts out 1300 watts RMS at 2ohms, the subs have an RMS power range of from 75-350 watts, and you'll be driving them with 650 watts each. A better power match would be to series the subs to present an 8ohm final load. This will reduce the output power to a level the subs can handle. Or you could buy 2 more 12.1's and connect them series-parallel for a 4ohm load and each sub would still be getting 325 watts RMS, just about the maximum they are rated to handle. Hope this helps.

I want to know how to wire a speaker


Weather of not you can use this speaker as an extension cab depends on a number of things. First, what amp are you planning you use for it? What is the minimum resistance for this amp (2ohm or 4 ohm probably). Second, what is the primary cab you are using ans what is the resistance on that? (2ohm, 4ohm or 8ohm).

Is there just one speaker in you proposed extension cab? The goal is to have all the speakers wired in parallel without lowering the resistance to a point that will damage the head. So if your amps minimum resistance is 4ohm then your cabs will have to both be 8ohm, running in parallel the overall resistance will be 4ohm.

Whats is the perfect amp?


I have 2 of these 12" running in a Large slot ported box with an:
"Ultra Linear UL2402"
600RMS X 2 @ 4Ohm (Stereo) 1200RMS X 2 @ 2Ohm (Stereo) 2400RMS X 1 @ 2Ohm (Mono)
Can be run in Tri-mode with 3 8Ohm subs, which these subs are. I have not tried this mode. This is
600RMS X 2 @ 4Ohm = Max RMS of your subs. You should run the max of your subs, less wear on the amp you are using , and i doubt you will ever need to turn it up far before it blows out your trunk or window :P
1200RMS X 2 @ 2Ohm = Blown Subs!
Has 4 x 25amp fuses, most will tell you this only has an RMS of around 845, an "ultra linear circuit" produces twice the output power over Modern amps.
Can had on Ebay for around $100. I bought mine for $101.
This Amp pounds, i could quickly tell a difference going from 300RMS X 2 @ 4Ohm with a Kenwood amp. I Had to turn all my settings down on the new amp to have a better balance in sound.

Behringer ep2500 amplifier


Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...

If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.

If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....
