Infinity Reference 1600a Car Audio Amplifier - Answered Questions & Fixed issues

If your single sub is a 4 ohm sub, you just connect + and - on the amp to the corresponding + and - terminals on the sub.
If it's a dual voice coil sub, it would have to be 2 ohms per voice coil or 8 ohms per voice coil to be able to achieve a 4 ohm load.

This will show you exactly how you'd need to do it:

Placing the speakers next to each other face down, you will notice that the connection points run in sequence +- and +-. Now connect the - (negative) from the one speaker, to the + (positive) of the other speaker. Now connect the open + from the one speaker and the open - from the other speaker to your amp. Your amp should have a bridging indication. On the connection points of the amp, you should see a mark pointing to the first + and the last -. That will be your bridge and thus utilizing the full potential of your amplifier

Check your wiring to make sure non of the wires are touching ground. If one or more of your speakers are blown, it could cause an open or short (or throw the impedence of the speaker(s) way out of specs). One way to tell if your speaker's voice coil is blown is to physically move the cone in and out from as close to the edges of the dust cover of the speaker coil as possible (not on the dust cover) keeping equal pressure on all sides. If you hear a gritty sound, it could mean your speaker's voice coil is history. On most high-powered amps, it's important that you're not using a common ground (some older inexpensive car units did this so you'd only have to run a single wire to each speaker and use the car body as the ground point for each speaker). I doubt seriously your system does this, but that's why it's important to make certain that the speaker wires are not grounded. You can disconnect the speaker wires from your amp and check each wire for continuity to ground with an ohmmeter.

Also, check the ground point of your amp...if it powers up, the source voltage is probably okay, but there's nothing wrong with running a cable directly from the battery just to make sure.

Good luck...

Try the head unit settings as depending on the head unit it can controll the amp sepratly

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts on either terminal when you drive the amp hard, you need to check the wiring feeding whichever line is dropping too low.

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?

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

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

what colours are those can you please specify them diff design for diff unit

hi Frank. if you go to this link have a scroll down the page and have a read up on what has been said about the amplifier you are talking about. Need power plug for infinity amp model 255 . plus i am finding out that you try ebay might help you but its not called a power plug. they are calling it a WECO connector..or.. U need to buy a cable, usually red and has a fuse. . or call the manufacturer.

The most common cause of this is the capacitors in the crossover network fail and cause all the wattage to go to that speaker.

Your amplifier module needs repair.

battery fried

SEE THE VIDEO ATTACHED AND FIX IT. GOD BLESS YOU

Is the code on a sticker in your glove box . If not youtube the type of car and sometimes you'll get lucky they tell you the code and the steps

Its not WATTS its OHMS.
