are you running a large ground wire directly to the battery negative terminal?

SOURCE: no sound out of subs

Check the ohm of your soeakers again. If it doesn't say 2 ohm thats the prob. Keep in mind that 2 ohm can be any where from 1.7 too 2.3 but any reading on you DVOM that gives you two decimal places is also wrong. i.e. 2.17. This would mean that you have a woofer shorted.

If thats not it and you have already fixd a ground then use your meter to check the ground; to do this set the DVOM to ohms and touch one lead to a true gound, by that I mean scratch the paint and primer off of a spot you can hide untill you see bright mirror like metal. Then disconnect the ground wire from the amp and touch the other lead to it. You should read anything from 0.3 to 0.1 any higher and your ground isn't that great.

If thats not it, The only thing left is to hook the amp up out side of the vehicle away and not connected to ANYTHING that has to do with the car. Get a battery and a diskman or a playstation, anything that can pass sound out of RCA's (Maybe even a diff radio if poss). Hook it up. If it works its in the car and let me know. I'll tell you some more to check, If not its the amp. Good Luck

The most common cause for an amp to go into protection is shorted output transistors. To eliminate other possible causes, read through the following page.

Troubleshooting - Amp in Protection

Let me know if you have any other questions.

Either You Fired Your Amp Or Wires, If You Got The Money Replace The Wires, Also Trying Grounded Your Ground Wire To Something Else.

A blown speaker will trigger the protect mode, sotry to power upthe amp with the speakers disconected, If you are still in protect, then the amp is bad.

kappas are 2ohm. You are running that amp at 2ohms stereo on front and rear channels. That is a nice amp, but it is a thirsty one. If you have a sub amp as well, then you are not supplying your amps with enough power. drop down to 0 gauge and see if it heats up anymore. Also, try going high pass if you have subs. If you don't have subs. You need to run 4 gauge and make sure you have a great ground.

Sometimes these amps have been known to get hot very easily. That said, I would first confirm the resistance on your speakers at rest is 4 ohms each, so that your amp is seeing a 2 ohm load. Be sure that the smart switch on each sub is flipped to the 4 ohm mode, and measure each separately.
Be sure that you've properly set the filters, gain, and bass boost so that your amp is not being over driven. Your HP filter should be set no lower than 20Hz--most music is never going to go that low so there is no point. A narrower frequency band is always going to be healthier for your subwoofer. The LP filter should be set no higher than 90 to 100 Hz at the most, depending on how much midbass your speakers can handle, so that you don't have too much of a sonic gap between the subs and mids. As for the gain, a good place to start is with your radio set at it's highest comfortable, distortion free setting, minus 25%, then start with the amp's bass boost all the way down, and the gain set to the minimum level at which you can just begin to hear music. Choose a bass heavy track if you ever listen to bass heavy music, so we can prepare for the most stress that the amp will experience. Slowly turn up the gain until you start to hear distortion during heavy bass hits, and back off 20% - 25%. This should be the highest volume you ever push your amp to, and from here, you can ever so slightly turn up the bass boost if you absolutely must, but not to the point of any distortion, if you hear any, back it off a bit.

one of those wires on your speakers is the common ground for both sets of wires in your camaro, Just take the negative wire from both sets of wires and run it to the single wire on your new speakers. The other 2 are positive from each wire. good luck

I just bought a 98 concorde lxi and no sound coming out of the speakers, radio comes on and shows channels just no sounds


Hello georgouseyes,

The problem could be in the output from your receiver to the amp or in the amp itself.

First check to see if the amp powers up. If it doesn't, check the main power fuse (usually located under the hood near the battery). Also check the power and ground connections on both ends.

If the main fuse checks OK, check both onboard fuses. There's 2 35A fuses on the far right.

If the amp powers up OK and the onboard fuses are not defective, it's possibly the output from your receiver or line output converter. Replace the RCA cables with a known good pair. If there's still no sound, I'd suspect that the amp itself is defective.

Hope this helps.

You sold the subs, or sold the infinity kappas? After selling a sub system it is often more than disapointing to go back. It often does sound quiet. You can either deal with it for a couple months until you get used to it, or I'd go with a set of MB Quart to replace your kappas.

Need power plug for infinity amp, model 255 a


car amplifiers don't use power plugs? U need to buy a cable, usually red and has a fuse. You probably want a 4 gage wire and u cut it near the battery and place a fuse in there and then follow the rest of the lead to the amp. Make sure your amp is grounded first!

No "fault" lights? If not it HAS to be a connection...whether they look bad or not, Redo them, ground FIRST.

Infinity 336rms amp worked for over a year then one day stopped?


check your fuses. Also check the power wire connection to the amp and then the ground source maybe move that if there is paint under it. check fuses on the amp. Check ohm load to the amp from the speakers.

Lack of power, or bad amp?


Check your ground. Its just as important as the power supply. Take off any paint, good ground means good power, check the fuse on the amp and any connctions to the battery other than that i would exchange it
