I have a 1500 watt Boss Armour Monoblock Amp. I hook 1 subwoofer into where the speaker goes and it works fine. I hook 2 subwoofers in and it starts pulsating. What am I doing wrong?

SOURCE: Car Audio Problems-Amp cuts out

No the reson for the amp overheating is do to the OHM ratting that you have the sub if to have the both wired up then just wire  one up and that will give you the OHM ratting that your amp is ratted for the way that you might have it is the way that we wire them for coms. where it is on for 30sec and no more. if you would like more help let me know.

SOURCE: how do i wire a qvc subwoofer to a 3000w 1ohm stable monoblock amp

depends on the amplifier if you have a mono block amp or a regular 2 output amp if it is 2 output make sure to bridge and that means the negative to one output and positive to the other output then need to find out the rms on the speaker. the amp should have the ability to adjust it you might want to get a digital multimeter set it to watts and make sure you only set it to the RMS of the speaker because max handling should be the 1800 and usually the RMS is half the max so it should be 900 w again it depends on the amp and were the adjusting knob is and or if it has one

SOURCE: How do i wire two 15 inch subs to 2 ohms

Hello familia_gome,

Those MOFO-15's have dual 1ω voice coils. So the only way you can get 2 of them to present a 2ω load is to use 1 voice coil on each one with the two of them wired in series. Using both voice coils, you can get a 1/4ω load by wiring the voice coils in parallel and then wiring the subs themselves in parallel. You'll get a 1ω load with the voice coils in series and then parallel the subs. Or you'll get a 4ω load with both the voice coils and the subs in series.

Here's a link to Power Acoustik's PDF for the MOFO's. I recommend that you check out the wiring diagrams on page 3.

Hope this helps.

SOURCE: 1 subwoofer stopped working in a box for 2

Hello mccanello55,

You need to remove the subs from the box in order to check the internal box wiring. First, make sure that the wire going from the nonworking sub terminals to the enclosure terminals is OK. Then check the "braided" leads on the back of the terminals going to the speaker cone. If the wiring all looks OK, remove the wires from the sub terminals, and use a multimeter set to the lowest ohm range and check the resistance across the subs terminals. You should read somewhere between 3-4 ohms. If the meter reads infinity (that is no reading at all), then the voice coil is open. If it "pegs" (reads "0"), the coil is shorted.

Either open or shorted means the voice coil is no longer working.

I could not find any replacement parts on Sony's support page, so it's most likely that they don't even repair these. They probably just replace the sub if it's under warranty, and if it's not under warranty, they probably recommend that you buy a new one.

Hope this helps.

Have you installed Kicker capacitors? With the extra power you have you will need them to help with the load.

I have 4 wires what do they do I no to of thim will go to my Kicier ame I Ddont no were the other to go


OK, I am assuming that you have 4 wires coming from the subwoofer itself. Your subwoofer has dual voice coils, this means there are two positives and two negatives. Look closely at the posts on the subwoofer and you can tell. These wires will go to your amp, all four of them. Here's the tricky part. You need to know if your amp is a monoblock (single channel) or two channel amp. Also, what ohms is it stable at (4, 2, or 1). If you have a monoblock stable at one ohm, take both positives from the sub and put to the positive of speaker output on the amp. Then put both negatives from the sub to the negative speaker output of the amp. If your sub is dual 4 ohm voice coils, this will give you a 2 ohm load. If you have a dual 2 ohm voice coil sub, this will give you a 1 ohm load. If you amp is 2 channel, just hook one set of positive and negative to one channel and the other set to the other channel. Hope this helps

Can i wire one speaker to the other speaker inside the box so that i only have one positive and one negative cable wire coming out out of the box and to the amp


Hello... I can help you with this question. Yes it is possible to do this, but you will have to use a 2 ohm stable mono block amplifier in order to do this. By connecting both positives together and both negatives together, you will be running a 2 ohm load. So if your amp is a monoblock amp, connections will be simple as tieing all the positives together and the negatives together and just hook to the amp. If you are using a 2 channel amplifier that is bridgeable, then you will need to series the subwoofers to an 8 ohm load and then bridge the amplifier to 1 channel. The way you series the subwoofers is take the positive wire in the box and hook to the positive on subwoofer #1. Take the negative wire in the box and hook to the negative on subwoofer #2. Then take a piece of wire and hook the negative from subwoofer #1 to the positive connector on subwoofer #2. Then hook the wires to the amplifier. To bridge the amplifier (if it is a 2 channel bridgeable) would be to use the left positive and the right negative, but check the amplifier for markings to confirm this. If you have any other questions, feel free to let me know and I will help you out! Hope this helps!!

Can you push a w6 with a 1500 phantom boss amp?


I can assume that phantom 1500 is a 1500 watt amp? but still the amp will have more than enough power to push a w6, w7,and even in pairs. Single w6 can handle 600 watts rms, thus you will need to turn the gain all the way down so that the speaker won't over powered and that can lead to breaking the sub.

Jl audio w7 13 subwoofer system 3ohm driver bridge it 2 ch amp


How much is your speaker max wattage?
If it is 750 or below, it can only be used on one channel, either the right or the left.
If speaker can handle 1500 watts then hook the positive speaker wire to R+
Hook black negative speaker wire to L-

Now it is bridged

Problem with subs and amp


I would first suggest un-hooking the subs, and hooking them up to another known good radio other than the one its hooked to now. Just to make sure you didnt blow the speakers. What is the wattage of the subs? Then if the speakers do work I would hook them up bypassing the amp just to see if the problem exist before or after. Come back after doing this. Thanks

Is amp big enough for speakers


Hello,

To run 2 subs, the amp would be a little small. The subs will run OK, they just won't be very loud.

It's usually better to compare and match up the RMS power rather than the peak power. The Sony XS-L10P5B sub has a peak power handling figure of 1200 watts, but the RMS is 300 watts. The Sony XM-ZZR3301 monoblock amp puts out 1100 watts peak, but only 330 watts RMS. They would work great together, 1 sub, 1 amp. But if you add another sub, each one would only be getting about 165 watts. They'd work OK, just not as loud as they could be.

Hope this helps!

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.
