Laney Pro Tube 100 watt guitar amp can't find schematics not an AOR
I'm sorry to hear about the issues with your Laney Pro Tube 100 watt guitar amp. Based on the information provided, it seems that the amp may have experienced damage from the lightning strike. Here are a few steps you can take to troubleshoot the blowing fuse issue:
- Check the power tube(s): Make sure the power tube(s) are functioning properly. You can try swapping them with known working tubes or have them tested by a technician. Faulty power tubes can sometimes cause issues with the fuse blowing.
- Inspect the wiring: Examine the internal wiring of the amp for any visible damage or loose connections. If you notice any wires that have been melted or disconnected due to the lightning strike, they should be repaired or replaced. Be cautious when working with electrical components and consider seeking professional assistance if needed.
- Test the rectifier tube (if applicable): Some tube amps have a rectifier tube responsible for converting AC voltage to DC voltage. If your amp has a rectifier tube, it's worth checking its functionality or having it tested. A faulty rectifier tube can lead to issues with power supply and fuses.
- Use a variac for testing: If you have access to a variac (variable autotransformer), you can use it to gradually increase the voltage supplied to the amp during testing. This can help identify any underlying issues that may be causing the fuse to blow, such as excessive current draw.
- Consult a professional technician: If the above steps do not resolve the issue, it's recommended to seek assistance from a qualified technician who specializes in tube amp repair. They have the expertise and tools necessary to diagnose and repair complex issues like this one.
2500 power acoustic amp green light no sound to subs
There could be a few potential reasons why you are not getting any sound from your subs even though the green light on your Power Acoustic amp is on. Here are a few things you can check:
- Check your wiring: Make sure that all of your wiring connections are secure and that there are no loose or frayed wires. Check that you have connected the amp to the correct terminals on the subs and that the speaker wires are properly connected to the amp.
- Check your settings: Check the gain and crossover settings on the amp to make sure they are properly set. Ensure that the crossover is set to the correct frequency for your subs and that the gain is not turned down too low.
- Check your power source: Check your battery and alternator to make sure they are providing enough power to the amp. If they are not, you may need to upgrade your electrical system or add a capacitor to your system.
- Check for a blown fuse: Check the fuse on the amp to make sure it has not blown. If it has, replace it with a fuse of the same amperage.
If none of these steps resolve the issue, you may need to take your amp to a professional for repair or replacement.
Subwoofers don't know if anyone answers these on here but I'll give it a shot
It sounds like your amplifier may be clipping, which can cause distortion and eventually damage your subwoofers. This can happen if you turn the gain or bass boost too high, or if you are pushing the amp beyond its rated power.
Here are a few things you can try:
- Check the wiring: Make sure that the positive and negative speaker wires are securely connected to the amplifier and the subwoofers, and that there are no loose or damaged connections.
- Adjust the gain: Turn down the gain on the amplifier to reduce the amount of power being sent to the subwoofers. Start with a low setting and gradually increase it until the subs are playing at a comfortable volume.
- Check the bass boost: If your amplifier has a bass boost feature, turn it off or reduce it to a low setting. This can also cause the amplifier to clip and damage the subs.
- Check the impedance: Make sure that the subwoofers are wired to the correct impedance for your amplifier. Wiring them incorrectly can cause the amp to overheat and shut off.
If none of these solutions work, you may need to have your amplifier and subwoofers checked by a professional.
I have two 12" jl w3v3.4 subs and a rockford 1500.1
Based on your setup, I would recommend wiring your JL W3v3.4 subs in a dual 2-ohm configuration. This will result in a 1-ohm load to the Rockford 1500.1 amplifier, which is within its safe operating range.
To wire your subs in a dual 2-ohm configuration, you would connect the positive terminal of one sub to the positive terminal of the other sub, and then connect the negative terminal of one sub to the negative terminal of the other sub. Then, you would connect the positive and negative of the combined subwoofer terminals to the positive and negative terminals on the amplifier, respectively.
Here's a diagram to help illustrate the wiring process:
luaCopy code
+ Sub 1 + ' --- ' +-------+-------+ ' ' + + ' ' + Sub 2 + Positive from Sub 1 -----> Positive from Sub 2 Negative from Sub 1 -----> Negative from Sub 2 Positive from Subs -------> Positive from Amp Negative from Subs -------> Negative from Amp
Keep in mind that you should always double-check your wiring with a multimeter to ensure that you've wired everything correctly and to avoid damaging your equipment. It's also a good idea to consult the owner's manual for your amplifier for specific instructions and guidelines on how to wire your subs.
Manual for volfenhag zx 7190
The manual for the Volfenhag ZX 7190 amplifier will provide the specific instructions for connecting the amp to your system. Here are some general steps for connecting a car amplifier:
- Connect the power cable: Run the power cable from the battery to the amp, making sure that it is securely connected.
- Ground the amplifier: Connect the ground wire from the amp to a metal surface in the vehicle, such as a bolt on the chassis.
- Connect the RCA cables: Run the RCA cables from the head unit or source device to the amp, and connect them to the input jacks on the amp.
- Connect the speaker wires: Run the speaker wires from the amp to the speakers, making sure to match the positive and negative connections.
- Turn on the amp: Turn on the amp by switching the power switch to the on position.
It's important to make sure that the amplifier is properly connected to avoid damaging the amp or your vehicle's electrical system. Additionally, you should also refer to the manual for your specific Volfenhag ZX 7190 amplifier, as the connection process may vary based on the model and features.
How to install a mono amp and sub into a system that already has factory versions of those?
Installing a mono amplifier and subwoofer into a car audio system that already has factory versions of these components can be a challenging task, as it may require modification of the existing wiring and possibly the use of additional adapters or interface modules. Here are the general steps you can follow to install a mono amplifier and subwoofer into a car audio system that already has factory versions of these components:
- Disconnect the negative terminal of the car's battery to ensure that you do not cause any short circuits during the installation process.
- Determine the location where you want to mount the amplifier and subwoofer. The amplifier should be mounted in a location that is close to the battery and has adequate ventilation, while the subwoofer should be mounted in a location that is appropriate for the size and type of subwoofer you are using.
- If necessary, modify the factory wiring to create a clean signal path for the amplifier. This may involve removing the factory amplifier or bypassing any factory equalization circuits.
- Install the amplifier using the supplied mounting hardware and power wire, making sure to connect the power wire to the positive terminal of the battery and the ground wire to a solid metal chassis component.
- Connect the RCA cables from the head unit to the amplifier, and then connect the speaker wire from the amplifier to the subwoofer.
- Secure all connections and test the system to ensure that it is functioning properly.
It is important to note that the steps outlined above are just a general guide and that the specific installation process may vary depending on your specific vehicle and the components you are using. If you are not comfortable with the installation process, it is recommended that you seek the assistance of a professional car audio installer.
Why is my amp sparking when i connect the wires?
A powered sub amp is permanently powered, but only when the key is at Acc (Accessory), or the vehicle is running. If it does it with engine off and key removed, there is probably an internal fault. There is a small possibility that the BCM is monitoring the Sub.
