Sounds like one of the channels on your amp is playing up.take it to an audio specilist to have this checked. if your rear right speaker isnt working this wouldnt cause the sub to stop working

How do you wire a AW1000V to 1 amplifier?


The easiest way to wire this would be to make sure you have a 2 ohm amp, wire both voice coils in parallel to the amp. This means to connect both + terminals on the speaker to the + speaker output on the amp, then wire both - terminals on the speaker to the - speaker terminal on the amp. With the voice coils in parallel like this it makes it into a 2 ohm load at the amplifier. If you are running for example a 1000 watt amp at 2 ohms into this speaker it would give each voice coil the equivalent of 500 watts of power at 4 ohms. The other way would be to run the voice coils in series (voice coil 1 - terminal to - speaker terminal on the amp, voice coil 1 + terminal to the voice coil 2- terminal, voice coil 2 + terminal to the +speaker terminal on the amp.) The series wiring would give you a 8ohm speaker load to your amp so you would need a 8 ohm amp.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty.

Im just hooking subs. to my amp , so do I run my woofers to the terminal that say's sub or to just the other speaker terminals.the thing is I have two ssubs. and one sub terminal


If you want to use two Kicker Coaxial or Component Speakers on a single
channel of your amplifier wire the speakers in series. This will improve the sound quality, lower the total harmonic distortion and
lessen the thermal load at the amplifier. This may prevent an amplifier from shutting down, due to over-current protection circuitry.....so definetly on the SUB terminals as this channel provides the better bass response........

I have 2 15 inch L5 solo baric subs and need a amp?


the 15" l5 is rated at 750 watts rms so i suggest you get an amp with atleast that much power because if you get a amp weaker than that you run the risk of clipping your subs and blowing them

I have 2 15 compvr how do u hook the 2-&da2+ in da back of the speakers.


it depends on the amp your using and the impedence of the coils.(ohms) for general purposes lets say that you amp is designed to run 500 watts bridged mono into a 4 ohm load. Lets also say that your subs have dual 4 ohm coils on them. To achieve the 4 ohm load you would want to run the coils in series on each sub,meaning that one of the positives is going to connect to the negative on the sub the remaining + and - terminals are what you will connect your speaker wire to. you just turned your dual 4 ohm coil sub into a 8 ohm single coil speaker. Do the same thing to the other sub and now you have a pair of 8 ohm subs with a set of wires coming from each. Now parallel those sets of wires together( + and +) and (- and -) and run that to your amp. This will give you a 4 0hm load at the amp

Have 2 4+4ohm avi sl500 subs how do i wire it to this amp and what setings on this amp alpine mdr m1005 1000watt amp


using these subs will limit you to a 4 oh load to the amp witch will only let the amp produce half of it's power. the lowest ohm load that amp can handle is 2 ohm and the next lowest you can wire the subs is 1 ohm and that will over heat the amp and destroy it. so to answer your question first wire each sub like this diagram shows...
Wiring Option #1
1_4ohmdvc_2ohm.gif
then once both subs are wired this way you wire both positives from each sub to the positive side of the amps speakers terminals and wire each subs neg. to the amps neg speakers terminal. the wire is series parrelle and will present a 4 ohm load witch will be the safest to run with your amp.

What is the best way to wire two alpine SWR 1222D subs to a alpine PDX 1000 1


First off excellent choice on audio equipment, i guarantee you won't be disappointed. So your subs are dual coil 2 ohms. So wire each individual sub in series. If you don't know what this means i'll explain. On each sub there are 2 sets of wire terminals. Connect a wire from the one set's - to the other set's +. Do this on both subs and you will have the coils wired in series making each sub 4ohms. Now to hook the subs together you'll need to wire them in parallel. Now since you have your coils in series, on each sub you have one + terminal and one - terminal left. So run a wire from the + terminal remaining on each sub, and run them to your amp. Splice the ends of the two wires together and plug them into the + speaker output of the amp. Connect the two negatives in the same way and plug them into the - port on the amp. You will now have your amp running at its desired 2ohms. When wiring this disconnect the fuse on your amp power wire to avoid short problems. And if you get confused at all, and aren't sure what to do, ask again don't guess, if its done wrong you could severely damage your equipment. Hope this helped, enjoy the bass...

Sub woofers and amp


first of all is the amp a four way amp? if so then you need to know what the watts of the subs are (you dont want to melt them) wire + and - of channels 1 and 2 to one sub and + and - of channel 3 and 4 to second sub, nice thick lead from battery positive (fused) to positive terminal on amp thick lead from a good earth point to negative terminal on amp run a set of rca leads down the opposte side to the positive wire to prevent interference, run thin wire from remote wire of radio to the remote terminal of amp, rca's are plugged in at stereo and at the am. may need a RCA splitter to be able to power all four channels

Good luck Davelee

Running 4 12s with two insignia 1000 watt amps


Use a pair of two-channel amps that are two-ohm stable, and wire a pair of subs to each amp. Wire them in parallel so the amps see two ohms (wiring in series will show four ohms). Doing this effectively "doubles" the power of the amps. If the amps are not two-ohm stable, they'll fail. Parallel wiring means putting the positive wire of sub 1 to the positive terminal of channel 1 on the amp, and the negative wire of sub 1 on the negative terminal of channel 2. Do the opposite for the second sub. This will give you a LOT of bass response as long as your sub enclosures are properly sized for the speakers.

Confused about system


If what you're telling me is correct you're trying to drive a stereo sub -woofer with a mono amplifier. If so, that could be a bad situation for the amp, if the voice coils are not wired together correctly. Before we go too far, I have some questions I need answered.
1. Is the MA unit an M1889i?
2. Do you have the 4 terminals of sub-woofer tied together. For example the 2 positive terminals are tied together & the 2 negative terminals are tied together?
3.How do you supply 12VDC to the amp?

While I'm waiting to hear back from you, I'll try to draw a schematic (wiring diagram) of the way it should be wired for your particular setup that I'll send to you.
