I'm happy I can help a newbie. I remember when I was one and I'm happy to help you. First off, I nodiced that the fuse is only a 30 amp fuse. A quick way to see what is probably the max output of your amp is take the fuse value, in your case 30 and multiply it by the voltage you will be supplying it. Lets say you are just sitting with the car off the voltage would be 12ish volts. So your total assumed wattage is 360 watts. Which is an large amount less than the 1000watts listed. So watch out for that. Also, with subs you would want a mono-block class-d amplifier. If you need any more help at all, let me know. Good luck

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:

http://www.modifiedlife.com/car-stereo-radio-wiring-diagram-1998-toyota-camry/

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 have an Infinity 530a 5 channel amp. new


May be the problem is on the sound you are using is not a 5 channel coded sound or check in the menu´s of the amp if the rear channel´s have sufficient db output, check the connections, check if you amp. is not working only as simple stereo (menus also)

Hope this helps

INFINITY AMP PROTECTION LIGHT FLASHING


Overload maybe. If the amp is run at an improper impedence, the amp will shut down. If you are "CLIPPING" speakers / subwoofers the light will blink to indicate a hard clip . Example: 4ohm/2ohm stable amp with 4 ohm subs wired at 1 ohm.

INFINITY AMP PROTECTION LIGHT FLASHING FOR 5 SECONDS


I have an Infinity amp as well, and I was having the same issue for a time. The amp is protecting itself from some sort of overload. It could be the Ohms load on the sub, but I would guess not. Make sure your low pass filter is set to LP and not HP or Flat. Then check the RMS on your subs and match that to the Amp RMS. Once I did all that I found that everything worked fine, for a time. It started doing this again, and I checked the fuse and it was blown badly. It seems that the fuse setup on some of these Infinity amps is not as good as one would hope, because the charge was bridging the gap and frying out my fuses. It was like a spark would jump from one side of the fuse to the other without travelling the fuse itself, and this was causing my protect issues. I pulled the fuse, got a new one of the same rating, but I placed the fuse in with a little piece of rubber in between the 2 contacts, and then connected to the fuse block. I have not had problems since.

You would do best with a 12volt inverter. It will bring the house voltage down to the necessary 12 volts for your car stereo. Best of Luck.

Powers on but no sound


Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?
