HOOKING UP 2 AMPS

I am about to install a kicker zx750.1 amp and a zx700.5 amp. What would be the proper way to ground and power these 2 amps. i'm familiar with installing amps just never did 2 in one vehicle before.

    On the 750.1 i will have 2 CVR122 speakers. They are 2 ohm subs. I have 2 RS65.2 and 2 DS650 speakers that i will be using on the 700.5 amp. If there's anything else, let me know and thanks for the help

    I'm assuming you'll be using just the 4 stereo channels from the 700.5 and the 750.1 will power your subwoofers?



    What kind of speaker/subwoofer load will you have on each channel?

Ideally you would use 1/0 gauge power and ground wire for the amps, and use power distribution blocks to reduce it to 4-gauge for each amp. Any smaller wire would be less than ideal for that much amp power.

If you're buying a power wire kit, it most likely won't have a separate distribution block for the ground wire (usually they have separate ground wire for each amp or one piece that's long enough to cut and have wire for both). This is fine, but you should look for a kit with at least 3 feet of ground wire per amp - any shorter and it's a struggle to mount the amp close enough to a ground point. As above, the main power wire to the battery should be 1/0 gauge.

Lastly if a 1/0 gauge kit is not available, 2 separate 4 gauge kits will work, however that's obviously a lot more wire to run and conceal.

My system is running hot!!!!!


your subs are the problem, not your amp, your wiring your subs paralelle, means dropping input ohmage, allowing your amp to over heat with minimal load, check the amp specs for running at low ohms, most hifonics amps are rated 2 ohms and higher, some however will run at 1 ohm, only on class b-a amps though.(competition) dropping ohmage will allow the amp to push more power to the voice coils, however the voice coils may not be rated for 1 ohm power, what ohmage are your coils rated at? do you have a min. of 100 amp inline fuse on your 1-0 awg wire? do you have internal fans? you can add mosfets to the amp but if you do so, you'll have to re-program your amps mother board.

Car audio hook ups


when installing a car audio sytem it is always wise to leave the power wire the last thing you hook up.ive seen many brand new amps fry because of people hooking power up to fast,if it sparks your in trouble, amps power wires should always be connect to the amp it self before connecting to the power supply. saves on amps:] And your ground should always be less then 3 feet on an amp the shorter the better!

Why is my Kicker 08zx650.4 amp turning off in my 98 Deville??


ive been hearing alot of this going on yes you had youre system proffesionaly installed but youre amp is pushing at all its got it must be pushing at 1ohms capacity loud but what you dont realize is that.. do ur home work first some amps say they can handle the power but if you read carefully it would read not stable look up amp on the net before buyin review them first ...but evrything youve got is correct its youre amp it wont burn out but you wont get continous power to ur spkrs ..i recomend installing one amp on each spkr same brand if you prefer in keeping it with a crossover if you dont have one that way they wont over heat and cutt off and you will use less power and get more bass...

Kicker protection light won't shut off


Hello newwithtech,

There are 4 possible causes for the amp to go into protection mode. Kicker calls it SORT for Short, Overvoltage, Reverse polarity, and Thermal. If the amp has been in and working properly, it's probably not reverse polarity. And if it goes immediately into protection when power is connected, I'd rule out thermal. So it's probably either a short or overvoltage.

1) Start by removing the speaker wires and see if the amp powers up properly. If it does, one or more of the speakers is shorted or grounded.

2) Test each pair of wires with a multimeter set to the lowest resistance (ohms) scale. Measure across each pair and from each individual wire to ground. Across each pair, the meter should read about 3-4 ohms. From each individual wire to ground, it should read infinity. If the meter reads "0" ohms (shorted) in any test, you have located the problem.

3) If the speaker wires test OK, set the meter to read DC volts and measure the voltage at the amp positive terminal. If the voltage is higher than 16V or lower than 9V, you've located the problem.

4) If the voltage is OK, remove the RCA inputs and test for proper power up. If it powers up without going into protection, you have a shorted/grounded input. Replace them one at a time to determine which one(s) is/are defective and replace the cable.

If these tests show all the wiring is good and the voltage is OK, the amp is probably shorted internally (most likely an output MOSFET), and requires service at the component level. You need to take it to your local audio shop or send it to Kicker for repair.

Hope this helps.

High wattage car stereo


positive (1 guage) from main battery to second battery positive terminal. hook all amps positive to second battery and hook 2nd battery ground to frame of car (where amp is now grounded) if you have a 2nd battery a cap is a waste of money. make sure all grounds (battery and amps) are together on same ground point of car, do not ground amps to battery - ground everything to 1 spot on the frame or body of the car ! - yes you can pigtail remote leads.

Kicker amps not working


With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Kicker 06ZX750.1 Car Audio Amp... Problem


Kicker amps are good amps, I would weigh the cost of a new one against getting this one repaired and go from there.
