Question about Peavey AMPLIFIER, 1000 WPC, DDT, 8/4/2 OHMS => Model PV2000 Car Audio Amplifier

1 Answer

4 ohms to 8 ohms

Ive just bought 2 pevey impulse 1012 speakers that are rated 8 ohms. I want to use them with my alto pbm8 500 powered mixer ( 500w per side) that is rated 4ohms. Will this set up work ok? will it do these speakers justice.

    Thanks for that. How do I set up parallel speakers ? Also the amp has 2 stereo inputs. How do I use those. Can I have a mandolin and harmonica going through the same stereo channel ? As you can tell i`m totally clueless!! Your advise is greatly appreciated.

    Thanks a lot . You have been very helpful. The last guy I asked told me to "Keep plugging thinks in until it does what you want it to do!!!"

Hi,

Offhand, the setup would work.

  • The disadvantage - the full potential of the Alto PBM8 would not be realized (though not a bad thing);
  • The advantage - the Alto PBM8 would not be driven as hard, less heat on the amp output.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

    Of course a better approach would be to buy another pair of Peavey Impulse 1012 speakers and wire two per side/channel. Two 8 ohms speaker wired in parallel is equal to a 4 ohms load to the amp.

    Hi again,

    Appreciate the postback/comment.

    Some additional ideas:


    • If you wire the + of 1st spkr to the + of the 2nd spkr and the - of the 1st spkr to the - of the 2nd spkr; that is parallel connection;

    • together the two spkrs could be treated as 1 with a combined impedance (resistance) of 4 ohms;

    • "mandolin and harmonica going through the same stereo channel" - will they not be using microphones? and therefore be treated as such? hence each will just use one of the 8 inputs.
    May I also refer you to another FixYa expert who is based in UK? Perhaps you may consult on him as well and maybe more advantageous due to proximity. We call him Ginko and clicking here would lead you to his profile. Thereafter, clicking on the "Ask Me" button would make your further queries directly visible to him. Doing the same in my profile would also make your questions directly posted to me so should you still desire.

    Cheers.

    Since your concerns were addressed, might I request that you reconsider the rating and re-rate this as you see it fit.

Amp comes on running 2 12" 450 watt pioneer subs, volume only seems to be about half output, with speakers bridged


This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.

Here are the specs for the AMP:
  • Specifications
  • Peak Music Power 760 Watts
  • Number of Channels 2
  • Load Impedance Capability 2~8 Ohm (Stereo), 4~8 Ohm (Bridged)
  • Continuous Power (4 ohm) 125W x 2
  • Continuous Power (2 ohm) 190W x 2
  • Continuous Power Bridged (4 ohm) 380W x 1
  • Frequency Response 10Hz ~ 50kHz
  • Total Harmonic Distortion 0.008%
  • Signal-to-Noise Ratio 100dB
  • Dimensions 12" x 2-3/8" x 12-3/4"
  • Features
  • Bridgeable
  • Channel # Capability 1/2/3
  • PWM Regulated MOSFET Power Supply
  • Screw-Type Speaker Terminals
  • Balanced Isolator Input Circuit
  • RCA Inputs 2 Channel
  • Input Level Control Hi-Volt (200mV ~ 6.5v)
  • Built-in Crossover Selectable LPF (80Hz, -12dB/Oct.)

    Need advice on setting up amp with my two speakers.


    This is hard to explain and what needs to be done is wire in parallel both subwoofers. This website will help just put in the amount of speakers and amount of ohms each and it gives you diagram.

    If the speakers are rated at 500W or greater, then you'll need two amps to get their full potential. When you connect two to a single 500W amp, each speaker only gets a max of 250W. Also, check the ohm rating for the outputs of the amp and the ohm rating of the speakers as well. Unmatches speaker/amp impendence also results in poor performance. If you connect two speakers to one terminal, the total impedence of the speakers falls by 1/2 (two 4 ohm speakers wire together will result in 2 ohm impedence). So, if you have an amp rated at 4 ohms, you could connect two 8 ohm speakers to a single output. Hope this helps some!

    I have a old peavey powered mixer 16 channel 250w rms can it push 2 pr15's rated @400rms-800w peak


    Of course, not, since it will be a mismatch 250w rms
    is much smaller than 400w rms. It will damage your
    mixer.

    What do you mean by the subs should have more watts than the amp.and subs mean woofer ? actually i dont know any thing abt this. what is 8 ohm stereo, 8 ohm bridged,4 ohm stereo. etc etc...?


    If your planning on using a stereo system in your car or home you need to follow some rules otherwise your just wasting money. The watts of a speaker means how much power it can handle. The higher the number the more power it can handle, and usually the louder it can get without distorting. If your amp has more power or close to the wattage rating of the speaker you will blow the speaker, it can even get so hot it ignites. The amount of ohms is the electrical resistance the speaker provides. House speakers usually have 8 ohms where car speakers tend to use 4. 8 ohm stereo means your left and your right are separate channels and each speaker has 8 ohms. 8 ohms bridged means you bridge the left and right channel to increase the power output of the amp and you have to use either 1 8 ohm speaker, or 2 4ohm speakers in parallel to prevent damage to the system. Same goes for 4 ohms. If I remember correctly you want your sub(woofer) to have a wattage rating 20% higher than the amp. Remember if the speaker overheats its no good, but most amps if they overheat they just shut off until they cool off, but only if they state they have a thermal overload protection.

    SHOULD I GO AHEAD AND BUY A 400 WATT AMP?


    All amps aren't created equal. More exspense amps put out "cleaner" power. You need to know what the RMS power rating is for the amp at 8 ohms and 4 ohms. Also, is the speaker an 8 or 4 ohm speaker? How you wire a speaker or speakers (series or paralell) can change the ohms (resistence) which will change the power put out of the amp. Also, I'm assuming you are setting it up in mono?

    Ive bought a Peavey 1500 pa amplifier and would like to know are the a b knobs on the front treble and bass.If they are how would I take the outputs at the back of the amp to my Soundcraft mixer.


    The Peavey A/B controls are output gain controls. Your mixers stereo output goes into the amps inputs, channels A & B. The Peavey is the output stage to your speaker system. If you you connect the outputs from a power amp to the inputs of a mixer you will blow the mixers input stage, amongst many other things and possibly damage the amplifier too. The bias (Bass, Mid, Treble controls) are on the mixer, not the amplifier. Unless you are using a mixer amp, which you are not. A PA system DOES NOT work in the same way as an intergrated hi fi amp.

    Dual voice coil wiring to class d amp


    The easiest way to think of wiring voice coils and subs is this:
    • Two items of the same impedance in parallel = Half of the impedance
      • 4 ohms in parallel with 4 ohms = 2 ohms
      • 8 ohms in parallel with 8 ohms = 4 ohms
    • Two items of the same impedance in series = Double the impedance
      • 4 ohms in series with 4 ohms = 8 ohms
      • 8 ohms in series with 8 ohms = 16 ohms
    In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:
    • DVCs in parallel, 2 subs in series = 4 ohms
    • DVCs in series, 2 subs in parallel = 4 ohms
    • DVCs in parallel, 1 sub = 2 ohms
    With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.

    Mmats d500.2


    • It is capable of driving a 2 ohm load.
    • It is a single channel amp, so bridging is not applicable. There are two speaker connections, true, but they are tied together internally.
    • It's rated at 500W @ 2 ohms
    • The issue you're going to have hooking up the subs you own is that you're not going to be able to optimize the output of the amp. If you hooked all of them up in parallel (both 15w0 as well as the dual voice coils of the 15w6), you'd be putting a 1.7 ohm load on the amp, which it may not like. In my mind, your best bet is to either put both 15w0's in parallel (125W per sub) and not use the 15w6.....OR.......use only the 15w6 with the dual voice coils in parallel (350W to the sub).

    Operate amp @ 2 ohm


    what is the output impedance of the unit - factory specs? use calculations for resistances in series or parallel to get what you want. for example if the amps output is 8 ohms and you have two 4 ohm speakers wire the speakers in series. if your output is 4 ohms and you have two 8 ohm speakers, wire them in parallel to get 4 ohms. another way is if you have one 8 ohm speaker and you want it across the 4 ohm output, find a wirewound resistor that'll take the wattage rated at 8 ohms and put it in parallel so the output sees a 4 ohm load.
