My boyfriend saw an amp with a spider on it in Mexico.They told him it couldn't be bought in the US.I figure it can.The only thing I know is that it had a spider on it and it was small.Can you tell me anything?

Re: looking for anp
Rockwood is available here in the US, but it might be a brand to stay away from! That company popped up after Rockford Fosgate and Sherwood became nameplates in the industry, and caused some confusion. Now they offer 5000W amplifiers with circuit boards the size of cell phones. GARBAGE!
The amplifier that is worth anything that you may have seen is Soundstream. Their tarantula line was so popular, when it got bought out, the new company retained the logo for all its amplifiers.
Look at www.soundstream.com for recognizing which amplifier it was. Im pretty sure that line now is pretty plain, but a limited ed. or older tarantula amplifier has a big spider on the front.
It is the only spider logo I know of in the 18 years I have been in the biz.
Here is an older model tarrantula... http://ampguts.realmofexcursion.com/Soundstream_Tarantula_5004/outside2.jpg
It is no longer available in this particular shell (see website for details). So that may be why you were told it cant be purchased here (anymore).
This is a nexer version with the logo etched instead of 3d. http://www.lightav.com/car/soundstream/tarantula.jpg

Your amp is straining for power, try upgrading your alternator or and a battery in your trunk... or capacitor.And also make sure that the fuse closest to your amp is the total value of the fuses in your anp
If you have the amp bridged mono to run both 15's, it's gonna get smokin hot. That's the nature of the beast. Just make sure it's got plenty of room around it to breathe, if you want to put fans on it, just make sure the fans you buy are DC voltage and noise shielded. If you surf the net you can find lots of electronics parts providers out there, just explain to them what you are trying to accomplish and that you do not wish to introduce ignition noise into the system and need a quiet running fan. That will at least keep air moving across the unit and draw heat away. End result, it can't hurt. Hope this helps
2 things to try, one. run your RCAs on the opposite side of the car as the positive wire. if you still hear the thumping try changing your RCAs. if you still hear the thumping, try a different anp or head unit. if you still hear the thumping, your subs are blown. best of luck
Dang! That's a class D anp! How did you fry it? If you "replaced" the internal ground wire and now it just blows fuses, I would say that the amp is direct shorted at the power supply if the fusesblow instantly when you put the fuses in.
Te dual inputsm are tied together on the output side thus having a "MONO" amp. Most class D anps are stable down to 1 ohm (check your manuel) therefore, 2 2ohm subs are a 1 ohm load. 2 DVC (dual voice coil) 4 Ohm on each voice coil will give each sub a 2 ohm load so 2 dual4 ohm V's will give you a 1 ohm load as well. Parrallel all conections.
What subs do you have? Is this amp 1 ohm ono stable?
When you bridge amp they some time double in power output into a certain load. If the actual load of your speakers are lower than the required bridged load the out put of the amp will proportionally try to increase again. You have to match your loads to the specs of your amp. Use your manual to see what is required, then use ohms law, for adding resistors in series/parallel to make your speaker load match. For more info please reply.
It sounds like you may have a power-supply problem. You need to measure the DC voltage across the B+ and ground terminals of the amp. If it doesn't remain near 12v when the amp is on, you need to determine why the voltage is dropping. It could be due to a defective fuse or a corroded connection at the battery.
There are some things I want you to check,
1) Make sure your ground is good and I mean very good, 0 ohms resistance to the negative battery terminal
2) Make sure that your AMP is grounded to that ground point you checked in step 1.
3) Make sure that your power supply B+ wire is one continuous run no taps or spliced connections.
4) Your speakers and woofers are all properly impedance matched to your amplifier (if your amp is 8 ohms then your combined speakers impedance must be 8 ohms total).
5) voltage regulation to amplifier is good.
6) Check all connections and ground points again
After these items are done power on your unit and then see if the problem happens again, if it does the issue is inside of the unit, one of the internal components has gone bad and you will need a schematic, a multimeter, and an audio tracer to work on the AMP with.
