20 Most Recent Infinity Reference 5350a Car Audio Amplifier Questions & Answers

Hi,
Most car audio amplifiers don't have on off switches.
So to reset the amplifier, disconnect it from the power source, from the car battery side.
Disconnect the positive side (red) first. Then the negative side (black)
Or sometimes its easier to remove the fuse next to the battery for the amplifier.
After its disconnected leave it disconnected for approx 5-10 min.

I hope this helps

try chk connection wire from spkr and amp

I would take it back to where you purchased the amp. As it should have limited one year warranty! At least it is worth a try.

Drivers side under the break booster. Should be a rubber grommet, but if not it is safe to drill there.

After reviewing the owners manual I can only guess that your amp is faulty and will need service. There is no reason for the power and protect lights to both be off while the power and remote wires are active. I'm assuming of course that power is still applied and remote is activated. It's difficult to diagnose problems online without voltmeter readings but my bet is on a faulty amp. In this case it will need to be professionally serviced. Before paying for service you could check the voltage at the 12V and Remote terminals, both should be 12volts. A solid ground is obviously required but it sounds like you have wiring covered. Feel free to post any updates and I'll continue to provide options if I can.

what are u using to play music??

I'am making over $15k a month working online. I kept seeing how some people are able to earn a lot of money online, so I decided to look into it. I had luck to stumble upon something that totally changed my life. After 2 months of searching, last month I received a paycheck for $15376 for just working on the laptop for a few hours weekly. I was amazed how easy it was after I tried the copy below web...www.join.hiring9.com

Question edited for clarity, and order, 'make model (what it is)'. No spares suppliers listed, but try the maker on Page 13. https://www.manualslib.com/manual/76933/Infinity-Hps-250.html?page=13#manual https://www.google.com/search?q=Infinity+Systems+HPS+250+Subwoofer+parts Or any good electronics shop will have the individual part. Have you tried electrical contact cleaner?

Your question can't be answered without knowing the impedance of the subs. Are they 1 ohm, 2 ohm, 3 ohm, or 4 ohm coils on those dvc subs? Are you saying your amp IS 2 ohm stable?

hi, if thats a dodge this might be it.. Re: Infinity Gold AMP Wire Diagram Well I don't particularly care for Haynes manuals, but my FSM's did not have anything either. I found this in thejeep cherokee haynes manual and it says that it is for 97 and later models but see if it is close. it looks like there are 2 harnesses so I will list them seperately: Hartness 1: [7] Left Soundbar Speaker (+) BR/YL [8] Left Soundbar Speaker (-) BR/LB [5] Left Front Door Spkr (+) DG [1] Left Front Door Spkr (-) BR/RD [9] Right Soundbar Speaker (+) DB/WT [3] Right Soundbar Speaker (-) DB/OR [6] Right Front Door Spkr (+) VT [2] Right Front Door Spkr (-) DB/RD [4] Power Amp Relay Feed DG/RD Harness 2: [05] Right Soundbar Spkr (+) TN/RD [13] Right Soundbar Spkr (-) TN/BK [06] Left Soundbar Spkr (+) WT/TN [14] Left Soundbar Spkr (-) WT/BK [11] Passenger Door Spkr (+) LB/RD [10] Passenger Door Spkr (-) LB/BK [04] Drivers Door Spkr (+) DG [12] Drivers Door Spkr (-) LG/RD [01] Power Amp Feed [02] Power Amp Feed [07] Power Amp Ground [08] Power Amp Ground The tweeters run in parallel off of the door speakers.... If I can help any more let me know. -Mike. https://forums.off-road.com/jeep-mid-sized/105694-infinity-gold-amp-wire-diagram.html

I'm assuming you're talking about the factory Infinity amplifier from a late 90's Chrysler/Dodge vehicle, and likely trying to reuse or repurpose this into another vehicle? See the attached photos for the wiring diagram of the stereo circuit with the amplifier, as well as the wiring pin-outs for both connectors

Could be a component inside the unit breaking down

FACTORY AMPLIFIER IS MADE TO DRIVE THE SPEAKER IN THE VEHICLE IF NO SOUND YOUR AMP NEED REPLACEMENT
