Infinity 475A Car Audio Amplifier - Answered Questions & Fixed issues
Accidentally got the power and
I would try it, if you haven't already, without any outputs (Speakers) hooked up, just the amp and the power...if the fuse goes again, it has an internal problem.
My amp keeps going in and out of protect mode

Your amp is probably OK. The volume is either set to
high or the speaker load is to low of an impedance. Remember 2, 8 ohm
speakers connected is the same as 1, 4 ohm speaker. Another possibility is that
you do not have enough battery power coming to the amp itself. A simple rule I
use is take the watts and divide by ten, that will give you an approximation of
the amps needed on a 12 volt system. This takes into account some of the
losses in the amp, but it is only an approximation. For example 300 watts RMS
is 30 amps, which will require a number 8 wire to keep the losses at a minimum.
You can check wire drops on the web.
Good Luck,

I installed a 475a to my door speakers and when i
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.
I just bought a 98 concorde lxi and no sound
Hello georgouseyes,
The problem could be in the output from your receiver to the amp or in the amp itself.
First check to see if the amp powers up. If it doesn't, check the main power fuse (usually located under the hood near the battery). Also check the power and ground connections on both ends.
If the main fuse checks OK, check both onboard fuses. There's 2 35A fuses on the far right.
If the amp powers up OK and the onboard fuses are not defective, it's possibly the output from your receiver or line output converter. Replace the RCA cables with a known good pair. If there's still no sound, I'd suspect that the amp itself is defective.
Hope this helps.
Sound loss
bad system cofiguration too much load on rea amp
Infinity 475a amplifier makes a high tone
Your stereo is picking up alternator whine. If you're good, you can make the motor fit with the song... kidding.
you can purchase a noise filter that will fit on the ground line of the alternator.... here's a few to scope
out onlinethis will get it out for ya...

Crossover issues?
if only highs are comin through subwoofer then check pf switch on amp then adjust crossover frequency to 80hz hope this helps
Bose amlifier
Power wire is usually yellow or red. A cheap test light from the parts store will tell you. The remote wire is almost alway solid blue. A volt meter will tell you for sure. Remember,the remote wire is very low voltage.
Protect mode on 475a
Yes if your wires are to small they dont supply enough power to the amp and it will shut down..Also the ground..Check all connections for tightness and that none of the wires are touching or grounding out...Hope this helps you and have a great day

Lack of power, or bad amp?
Check your ground. Its just as important as the power supply. Take off any paint, good ground means good power, check the fuse on the amp and any connctions to the battery other than that i would exchange it
Protect Mode
Hello,
first I would advise you to tighten all of your ground and power connections. Then I would suggest that you expose the circuit board and start the amplifier warm up process, once the amp comes on I would use freeze spray to cool down various components in an attempt to find the component which has become thermally sensitive. Once you find the component I would suggest replacing it and the putting the cover back on the unit.
I hope this helps,
Thank you,
