Have you tried to hook up another sub (spk) to the amp? Or just wire it to a stereo to see if it works? single voice coil or dual?

Your manual should have all info inside.

It may not be the subs, but the amp could have caused the subs blowing/freezing up. If an amp is clipped it will send to much voltage to the subs, thus blowing the subs. Clipping the amp is when someone sets the gains on the amp to higher than the sub can handle. Find this out before you buy new subs. If not, you may have blown subs again.

you can only do that if your sub has a switch on it otherwise just hook it up and pound it

Here is a link for wiring speakers:

Your speaker is a DVC so follow the Dual Voice wiring as it is universal set up.

they can be easily blown/burned out

Well, First you need to figure out a few things. How much room you have is one main consideration, If you go with a vented (ported) enclosure or band pass (see below) than you will need more room than with a seal enclosure, If you really have no room you can mount them " Free Air" which is mounted on a board and fired into the back seats, the Truck acts as the enclosure.
Now the type of bass you want is another consideration. The best enclosure for maximum bass is a bandpass box. It is 2 subs facing each other with one side fully enclosed and the other side ported. This is best for deep powerful bass but the enclosure can be rather large. Vented boxes are second best (In my opinion) they give you deeper bass and more power than the sealed boxes. Sealed boxes give you less power from your sub and are a little flatter. Some say that the bass is more accurate and tighter , depending on the type of music you play. Rock you would want a tighter bass(sealed) and hip hop or techno style you would want a deep bass(ported). Lastly you have the free air which gives you the least amount of bass and is usually rather flat sounding. If you have the room go for the band pass box, if room is an issue than go with a sealed and specifically design box for you vehicle. Alot of places design boxes for almost every car out there. Just make sure that have a well designed box, It makes a world of difference, than an improper box.

i would get it looked at, you never know. when ever your stuff starts to smoke it might work for a lil while but sooner or later my opoin it will be just junk.

Need more info. What subwoofers are you using, including specs, what voice coils, and so on, and what amp you're using with them specs on it as well along with how many channels and so on. I can help you out with this no doubt

If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long Box size will be 13 inches x 13 inches x 13 inches

sounds like the amp is sending dc voltage to the sub. you probably have bad output transistors in the amp.

Alphasonik... | 33 views | 1 helpful votes


yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

It's usually your ground. Make sure it's secured to something metal. If it's a painted metal, sand a spot down to the paint for the contact. It could also be a screwed up speaker or even interference between wires. Make sure they're separated and insulated.

depends on the impedance of the coils on your subs and if they are single coils or dual coils. If you are trying to achieve a 2 ohm load then a pair of 4 ohm coils in parallel will do the job.If you have dual 4 ohm coils on your subs then you will have to use only one coil from each sub which will still give you the 2 ohm load that you seek but it will affect the power handling of the subs by half as you are only using half of the coils.

Hello gaz69,

Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.

This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.

Hope this helps.

I used to compete with these subs, and found that for street beat 2.7 cu ft ported tuned at 38 hz was the best for this sub.

If using for max SPL your tuning will be much higher, like around 55 hz. But that all depends on the vehicle.

With an amp like that you can not pull enough power from you cars battery alone. That is why when it hits hard it drains the amps from your battery and you amplifier cuts out. The light on the amplifier most likely dims when the bass hits. You need to get a capacitor. They are easy to hook up on the main power wire. You can get one from http://phatcaraudio.com/capacitors.html or get a used one off ebay.com. Good luck
