What fuse is for the dash lights?

It is generally a small fuse about 5 amps. It typically feeds off the tail light fuse and goes to the dash dimmer switch. If the tail light fuse is blown, you won't get dash lights either.

88s10 Chevy is gray power feed tryin to install stereo wirin was set up differently when i got it?

If you are trying to install a stereo in a 1988 Chevy S10 and the wiring was set up differently when you got the truck the first step would be to identify the specific wiring setup that your truck has. You should be able to find wiring diagrams for the truck online or in a repair manual. Once you have identified the wiring setup you can then begin the installation process. Here are the steps you should follow:

  • Gather all the necessary tools and materials.
  • Turn off the battery and disconnect it.
  • Remove the dashboard trim and any other components blocking access to the wiring.
  • Identify the power source and ground locations.
  • Connect the stereo wiring harness to the power source and ground.
  • Connect the speaker wiring harnesses to the speakers.
  • Connect the antenna cable to the antenna.
  • Replace the dashboard trim and reconnect the battery.
  • Test the stereo system.

Once you have followed these steps you should be able to successfully install a stereo in your 1988 Chevy S10. Be sure to double-check your wiring connections to ensure that everything is securely connected.

Can you use a 400 watt speaker with a 300 watt amp?

The selection of an amplifier size is not obvious and most sound engineers will agree that an amplifier with the same output rating as the speaker rating is not a good choice. Here's why:

Speakers can take quite a lot of abuse. They can cope with signals that are distorted as long as they are low levels. They can cope with being over driven as long as the signal is clean. What they really don't like is a distorted signal when it is at full power. Signals that are distorted because the amplifier is clipping the top and bottom of the waveforms are some of the worst distortions that a speaker can suffer. Amplifiers produce exactly this kind of distortion when they are driven beyond their power rating.

If the amplifier output is the same rating as the speaker input rating, this clipping will occur when the amplifier has reached its maximum output which is also the maximum power that the speaker can handle. This delivers the distortion when the speaker is least able to handle it.

If the amplifier is much smaller than the maximum speaker power, the distortion tends not to be damaging even though it sounds unpleasant. If the amplifier can output more power than the speaker is rated to handle, you will start to hear unpleasant sounds from the speaker but normally the speaker sill not be damaged in this situation. In either case, a sensible operator will reduce the drive to the speaker and both amp and speaker are happy again.

Generally a professionally designed sound system will use amplifiers that are substantially larger than the speakers' rating. That allows the speakers to be driven to capacity without a danger of the amplifiers being over driven. A 400W speaker will often be driven by an amplifier with a rating of 600W - 800W.

In addition, most big systems will employ a speaker controller of some sort. These devices monitor signal levels and prevent the amplifier over driving a speaker. Although they provide a good protection system, they need to be set up manually so demand a significant amount of knowledge to be used effectively. In a commercial environment, speakers controllers are often locked away from all tampering fingers to prevent the setting being adjusted.

Why would dash and rear lights on a 2001 Kia Sephia not be working?

Check the fuse and relay marked TNS. check fuse fuse panel is labled with each fuse if you checked the fuse + the relays and everything is ok, it's your (DRL unit)or if you prefer = minus 150$!! Good luck and don't worry, it's really easy to change except for where they put this small box. (behind left side of dash!!)

If you install a sub do you need an amp too?

Well you are going to need subs an amp it depends on how big your sub and amp are going to be but you might need a new alternator a amp wiring kit also depends on how big you go if its over a 1000 watts you will need like 5 gage of 4 gage power wire it should tell you on the box a drill maybe to drill through you firewall if you don't hare a big enough hole that about it i think oh and a box for your sub

When screwing in the sub to the sub box don't forget to pre-drill all the holes before you put in the screws. If you don't it may crack and screw up you mdf.

Where is the fuse box on a 95 Pontiac Grand Am located?

If it is located where the 2001 Grand Am is, it is in the engine compartment and the fuse block is located on the drivers side, near the battery. It should be fuse number 42- Back-up Lamps, Brake Transaxle, Shift interlock.

How do you program remote key on jaguar s type?

Programing a remote key on a jaguar s type has to be done by a jaguar service center. Only authorized technicians should do it because often, people end up spoiling the remote system when they program it on their own.

What causes the fuse for the dash lights and tail lights to blow on a 1998 dodge stratus?

Check the plug-in for the trailer lights, if it has one. If not, check the Headlight switch. It probably has a burnt wire.

How do you get to the turn signal flasher unit on a 2002 Chevy Malibu?

I also have a 2002 Chevy Malibu that had the weird blinker issue. Last year I checked it out and found it was a recall. You should be able to have it fixed for free. Mine was fixed last spring and I haven't had any problem since.

Your 2002 Jeep Wrangler dash lights wont come on where is the fuse for this?

check the dimmer switch, turn the light know left and right. sounds like that is the problem. turn it with the lights ON!!

Check fuse panel in passenger foot well, two columns of small fuses. Check fuses #6 and #9. They are 6 and 9 down from the top in the left hand column. Try hitting the dashboard over the cluster with your hand. It's a common problem that the air bag light comes on and all gages drop. I get that now and then. Give the dash a hit and it comes back to life.

Where is the turn signal relay on a 1996 Chevy blazer?

The relay signal is found in the glove compartment, pops right out.

Added comment:

Don't be misled. The glove compartment in a 1996 Blazer that has AC only contains relays and does not drop down with a simple release mechanism. In this vehicle, the lower dash panels do actually need to be removed in order to access the flasher. You'll need Torx bits and hex sockets to accomplish.

1979 f150 wiring diagram?

Typically you can find an accurate wiring diagram in a service manual. Chiltons and Haynes are two good sources. Typically you can find an accurate wiring diagram in a service manual. Chiltons and Haynes are two good sources.

What is the location for the fuse that allows the dash lights to come on?

i have been looking for the same answer and connot find it. i have even tried asking ford and they just beat around the bush about wanting to charge a $200 fee too diagnois the problem The fuse is under the hood. It is in a black box under the hood on the drivers side. You most likely will find a blue fuse blown. If the fuses are good you might have the same problem I had. I had a broken wire in the wiring bundle under the hood. The Ford garage found repaired it for around $150.00.

Is better to have a mono amp or 2 channel amp to 2 sub-woofers?

You won't notice any stereo separation with two subwoofers because our ears perceive bass as omnidirectional. Two subs can make more volume than one of the same size. If you are using two subs, you should either use two separate mono amps, or a two channel setup. As long as the amps have a high pass filter they will work equally well, although the wiring will be simpler for the two Chanel setup.

Why do your lights stay on when you close the doors on your 1998 Ford Expedition?

I experienced this problem when I first brought my used '98 Expy home. I searched Ford Forums and found that the latches seem to get stuck in either of the doors (i.e. drivers. passenger and hatch) I sprayed W40 on the inside opening of the door latches and in the actual latch itself and slammed my door several times and to my delight, the lights went out (interior and running board as well.

How do you open a locked car door on a Chevy Astro?

IF you are looking to open the doors all the way. on the inside door frame you will find a guide and a spring that attaches to the door and the frame the flat steal guide set in a pin on the door frame lift it and it should pop off the pin this enables the door to swing all the way open.

Tires air pressure?

It depends on the tire type and the load of the vehicle. Tire pressure is the amount of air in a tire that inflates the tire to the maker's specifications. For specific tire pressure on a specific vehicle, please look at the sidewall area, as most tires display the recommended pressure according to maximum load.

If you have a sub woofer with 400 watts continuous power and 800 watts peak power do you need a 400 watt amp or a 800 watt amp?

well, your lookin at RMS when it comes to speakers and amps, if you bought a 800 watt amp, you would be looking at 400 RMS just as you do with your speakers, i would recommend a 1600 watt amp, just for the fact that you always want a little play room with your amp, this way you wont blow the amp, (amps are more expensive than speakers), and if you decide that you want to get bigger speakers, you will not have to replace the amp. But all in all, i would say anywhere from 1200 to 1600 would do just fine for your sub..-Shocker

How do you replace the rear turn signal bulb located on a 2005 Chevy Express Van?

Remove the lightbulb connector from the back of your turn signal. Take hold of the lightbulb, push in and turn at the same time. The lightbulb will come out. Reverse the process to install the new lightbulb.
