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?

I just got an alphasonik pma800da today, it came with the cord you are talking about. Looks like a phone cord, its to hook up 2 of these amps together. I also have the book to the amp

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

check your ground cable out . if your ground is too small or loose it can cause that also you want your ground as short as you can

Here is a link for wiring speakers:

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

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

they can be easily blown/burned out

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

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.

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

Alphasonik... | Answered on Mar 09, 2010 | 33 views


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.

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.

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.

Generally speaking if the voice coil is actually 'blown' (accepted too much power therefore reads as a short when connected to an ohmmeter) It would be cheaper to purchase a new sub woofer.

90% of the speaker manufacturing price is in the voice coil. The cage, driver and dustcap as well as the surround are inexpensive components.

I would suggest testing the voice coil with an ohmmeter first before you decide what to do. If the meter doesn't read a short then its likely a TV repair shop can reconnect the lead that attaches the terminal to the voice coil.

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.
