I made the mistake of placing the ground and power wires on the wrong terminals. The fuses popped immediately. The amp appears to still get power but the sub will not work. I tried another sub I knew worked and still nothing. I can't find a local shop to repair it. Does anyone have any ideas on how I could repair this myself?
If your good with electrical soldering circuit boards you maybe able to pull it apart it may have just popped a capacitor it should be obvious when u get it apart if it is then you could go to radio shack or order off the net what cap you need remember to use low temp solder when soldering to the board write down the numbers from the cap that is blown and order same to replace hope this helps

terminals. Internally in the amp the positives (1 and 2) are connected together and negatives (3 and 4) together. So there is no difference between hooking up in any of the configurations 13, 14, 23 or 2->4. If its a matter of style, probably use the 14 set, since they're furter apart and harder to short out that way, but electrically it doesn't matter.
Be sure the RCA cables are attached and in good condition.
Be sure the remote wire from the deck is hooked up and good.
Be sure the GAIN control is turned up.
Volume on head unit is up. Make sure BASS options are not turned off on deck.
Be sure wires are going the right way. + to + & - to -
Loose wires in the box. Make sure subs are hooked to the terminals inside box.
Check all fuses on amp to determine if 1 or more i blown.
Where is your ground located?
It never hurts to put a beefy ground on an amp. If you do have it grounded take the bolt out use a wire brush on the bolt and on the surface you are grounding to.
Also check our remote wire(blue). The purpose of this wire it shuts your amp down and turns it on when you turn on the head unit.
You're amp is not getting the maximium power then it once was. You must tighten the ground or reground it scrapining the metal. There is a lot resistance somewhere in your system. recheck your power connections making sure they are tight and not corroded already especially near the battery. take out the old fuse and replace it with a new one and see if the amp improves its power.
Sometimes the fuse internally breaks loose and has a bad connection without looking bad. You can measure this with a multimeter. See what the voltage on the side of the fuse holder away from the battery is. Is it 12 volts or does the voltage drop drastically.
For the amp to go immediately into protection, something is probably shorted, grounding out, or not grounding properly. First, remove and check the 40A onboard fuse just left of the power/ground/remote terminals. If the fuse is OK, disconnect the speaker wires and try powering up. If it powers up OK, check the speakers and wiring. If it doesn't, disconnect the inputs and try again. Check the grounds of both the amp and your receiver. If these check OK and the amp is still not powering up properly, it's most likely an internal component failure and the amp needs service.
Hope this helps.
ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .
Circuit City ? I'll keep that opinion to myself. If all is properly hooked up, Check the ground wire for the amp. Give it a tug where it is connected to the car chassis, NOT the amp, if it moves or comes loose thats easy to fix, scrape the paint off the grounding point use a high quality ring terminal and a oversize screw with a star locknut. Also check the wiring in the box. Subs and boxes are quite heavy. And if it's banging around, I hope you have it in a trunk, they are very lethal projectiles in a hatchback should you have a accident. My second thought is that you may have dislocated a component , solder joint, or cracked the PC board, When in doubt see a installer. Good luck Sumthin Sumthin
