Question about Infinity Reference 7541a Car Audio Amplifier

02 Dodge Durango Infinity (stock) system

The Stereo has started making popping and snapping noises and no matter what component I am using( cd, tape, or raido) it sounds like a raido that is not properly tuned in. At low volume it is very noticeable. It has the built in amp. and I do like to turn it up loud, so I figured it was on it's way out. I bought another one (used from an 04), but it is also making the exact same noises. So I am inclined to think it isn't the stereo that is the problem, but I have never had a problem like this. (All speakers are brand new as well). Any advice would be helpful.

How many watts does my infinity amp produce per channel in 2000 dodge durango

without knowing the amp size and model number it is literally a guess as to how many amps per channel or any other question regarding it.

if you have a multimeter that measures watts that would be the only way to tell otherwise. good luck

Install dual xd1222 into a 1993 dodge intrepid

The best way is to get a stereo installation kit designed for your car. It will have the surround for the new stereo to fit where the stock stereo fit. Also, it comes with a wiring harness that you connect the new stereo to then it plugs in to the stock radio plug. Most local automotive stereo stores should carry them.

1998 Toyota Camry Le Wiring Diagram. i want to hook a subwoofer with stock stereo. Need to know what to use so it will power off when car is turned off.

Hello motoxbear17,

You do not specify what particular amp or powered subwoofer you intend to install, so I'm assuming that you have an amp that uses a remote 12V+ signal to turn the amp on and off. Some powered subwoofer systems like the Bazookas, Infinity Basslink, and MTX Thunderlink use an "audio sensing" circuit that turns the sub on only when the radio is on. Some amps also have such a "turn-on" circuit that is active when speaker level inputs are used. I'd recommend that you check the documentation that came with your amp and see if it has such a feature.

For a normal subwoofer amp with power, ground, and remote terminals, the remote terminal usually just needs a 12V+ source to turn the amp on.

In your vehicle, the gray wire coming from the receiver harness is a 12V+ switched source.

Here's a link to the '98 Camry wiring color code:

With this connection, the amp will power on whenever the vehicle ignition is on or in accessory, regardless of whether the radio is on or off. If this is objectionable, you can simply add a SPST toggle switch inline with the lead and turn it on only when needed.

Hope this helps.

I installed a 475a to my door speakers and when i turn the power up on the amp my speakers make loud popping noise any idea on wat it could be

You blew the speakers. The speakers were probably not made for that much power and the voice coil blew. If they were stock speakers, then they are defenetly blown. Stock speakers are not made for much power at all, and will more than likely blow with any extra power given to them at all.

How do i connect a kenwood amp to my 2003 bmw m3 with a stock hk system and head unit? i just need to kno where to connect the amp to the car radio

You will need to connect your speaker outputs from the head unit to the high power inputs on the amplifier. If the amp only has low power inputs(rca jacks) then you will need to get a device that lowers the output signal from the radio so the amp can be connected. The red wire will go to the switched power. The yellow will go to constant power. Black goes to ground. Now the blue wire is the signal the amp gets from the stereo to turn on. Your stock stereo will probably not have this ability so you will have to hook that wire to the switched power. Your amp will come on whenever the key is on...even if the stereo is off. If your stock stereo has a wire that sends out a power signal when it is turned on you could try that for the blue wire. Just make sure you have the negative battery cable on the car disconnected so you don't short out your vehicle's electrical system while installing the amp.

Problem with Kenwood stereo

If the unit is old, I would start a he beginning and check the wiring connections. A lot of people use electrical tape without solder and it always works itself apart. Pay very close attention to the ground wire because it could be a common ground type system, meaning the battery ground is used for the speakers as well as the power for the eq.

Amp cuts out with loud volume

From what you describe it could be that its not getting enough power when the car is fully running. Its been a long time since I have had to deal with car audio problems. Does it happen when the vehicle is running but in park? If so it could be a short (Not likely though, it would be happening more often). Or it could be a loose connection somewhere that the vibrations of the vehicle are shaking. That would also be a problem if it happens when it moves. If it is still a problem, I would take it to a Checkers Auto. A lot of them offer free electrical testing.
