Power light vs. protect light mode

I have a general question..i never paid attention to the light on my amp...when i hooked it up after a couple years, there's a red light on, on the center of the amp in its emblem/lable....and i was wondering is this the power light or the protection mode light?  Because a while back my sub shorted due to a crimp from my speaker wire which was cause by my backseats folded down to the trunk shorted out the subbed and i saw the short on the speaker wire as well...i don't know if my amp was shorted out or not, b/c i took everything out and never messed with the amp til now....just wanna see what you would normally look at if you were looking at the amp to see if it's working properly..i opened it up and couldn't find anything wrong.  Does the amp have a separate fuse for it?...and one more question, if i was to hook up a sub to my amp to test it out...would it endanger my sub and cause it to short, is that possible?  please let me know ---thanks

If the power light on top of the amp is on, the internal power supply is operating.

It is possible that the amp could damage the speaker if it has blown output transistors. Before you connect a speaker to it, you should measure the DC voltage across each pair of speaker terminals. If the DC voltage is more than a fraction of a volt, the amp needs to be repaired.

The amp requires an external fuse. Download the owner's manual from the rockford site.The correct fuse for the amp will be specified in the manual.

You have ALL PROBLEMS diagnosed,resolved &

motor & other items

Yours is an OBD1 System (1981 thru 1995)

Google the diagnostic connector location,test

Lexus 2001 RX300 - What is it when the Trac Off, VSC & Check Engine lights are on at the same time while driving? Thanks!

I have no mechanical experience and my Lexus 2001 Off truck, vsc, and check engine lights came on while driving. After a research on the net. I paid 10.00 for a diagnosis and came up with the code P1135 A/F Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). I went to Autozone store in San Diego and purchase the sensor, 170.00 dollars. Went to a mechanic, lift the car up, pull the sensor out under the car and put the new one. The 3 lights went off. No more faulty codes. Labor 25.00 dollars. Except for the lifting of the car, the change of the sensor is like changing a spark plug. It was no difficult task and it took 15 minutes. 7/31/2010

42hp95 won't power up it clicks twice but red light just keeps blinking

This Toshiba unit must have been a "lemon", as the power unit was replaced about a year ago. It is only 3+ years old & we paid $1600+ for it in 3/96. Too bad. I'll never buy another Toshibaproduct.

Check a private shop out by asking around and seeing what people that have used them think. There are only a few manufacturers of heaters, and Just about every car company outsources them. The reason that the job is expensive is that nearly the entire dashboard needs to come apart to remove it. (in my opinion the engineers are morons...old designs were far more easily serviced except for took me 13hrs to do and I swore I'd never do another one!!!) When actually doing the job, close attention must be paid to all electrical connections for everything in general and servo "motors" that operate the heater doors. I've often seen a core replacement result in ancillary electrical problems if it's not done carefully. In the financial bind most dealerships find themselves in , most are trying to "wring" every dollar out of every job...Find a good private shop with a good reputation and techs that don't double talk or evade your questions and you should be fine. NO peppy boys or "discount" chain shops...they just can't do this work.
With the miles you stated, attention needs to be paid to routine service, with an eye to leaks, noises "odd " things you see and hear. It appears you are doing this already. Just keep it up.
I do a "look around" every few weeks and coupled with the use of synthetics, get over 350K out of everything I own.
Good Luck!!!

Red light on the amp.

Have you checked your speakers to make sure they're connected to the amp (a wire could have broken or pulled loose)?

Have you confirmed that you have a good signal reaching the amp?

The red light isn't always a good indicator that the amp is functioning properly. If you have speakers connected to the amp and have a good signal feeding the amp, the amp may have failed.
