Question about Kenwood KAC-7202 Car Audio Amplifier

1 Answer

Battery hook-up RV application. 4 AWG power and ground wires with no inline fuses. I did not do the original installation. I was having trouble distinguishing power and ground lines when I inadvertently touched the positive amp wire to the negative battery pole and got a spark. The negative side of the amp was tied to chassis ground. I then went to install the positive wire from the amp onto the positive pole of the battery. When I did this, I got another spark. Don't want to secure the positive cable until I figure out why I'm getting a spark when properly installing the wires to the battery. Any ideas? Thanks

You must have inline fuses at the point where the wire taps off of the power source. If you're tapping off a wire that has no fuse (like the starter solenoid), you must insert a fuse.

When making the connection to the amp, there will be a spark initially. If you hold it on for a second, pull it off and then touch it again, there should be little to no spark because the capacitors in the amplifier would have charged when you made the initial contact. If there is an intense spark each time you touch it and the amp is not on (no remote voltage applied), the amp may be defective.

Let me know if you have any other questions.

Jl500 amp... Been hooked up the same way for years. Power wire from battery with an inline fuse which goes back to the power block which goes to the amp. Perfect ground and remote wire to the deck. And RCA...


well the nasty spark it shoots its because you r to first connect negative first always and than positive or check ur main cable/fuse that is connected to your battery inside the fuse box its actually pretty easy to find just follow the positive red wire from your battery till u get to the fuse box it looks like its connected to negative and positive, check it it may be the problem(inside the fuse box), if it isn't you should check the main source of battery recharge which is your alternator it may be going bad

your inline fuse wouldn't blow if there was just something wrong with the amp. the amp fuse would blow if that was the case. something is faulty with your wiring. you probably have the wires touching somewhere or are in the wrong terminals at the amp or on the wrong battery terminal. or your power wire is grounding out somewhere. its not the amp. its your wiring

When i hook up my 750 watt inverter to my truck do i need to install a isolator or inline fuse? or just connect the 4 gauge battery cables directly to the battery and the inverter?


Yes, inline fuse as close to the battery as possible. If 4 gauge wire were to ground out without fuse, would most likely start a fire or at least damage other existing harnesses (depending on routing) before a person could disconnect battery.

Problem with power ausoutic 5500watt amplefier


With a 5500 watt amplifier you should be running 0 awg wire . You also need to be running an anl fuse holder with a 250 amp fuse underneath the hood by your battery. When the power light blinks like that it means that it needs more power - ie. that there is resistance some where in the system . With 4 gauge wire it just isn't getting what it needs. Make sure you upgrade the ground as well to 0 awg . If you have any other questions please feel free to contact me mmaudio545@yahoo.com

Legend Amp hook up manual.


Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

I would recommend using an 8 AWG minimum or preferably 4 AWG power and ground cable. Use as short a ground lead as possible and connect it directly to some chassis metal (avoid accidentally screwing into the gas tank if in trunk). Use a fuse holder with a 40 - 60 amp fuse under the hood within 18 inches of the battery. Your RCA cable coming from the back of the JVC radio should be run to your amp along with the remote turn on lead. This wire should connect to the JVC's amplifier turn on lead which should be a blue wire with a white stripe.

The 2 + and 2 - connections are the same, just split into two. This is usually because, for high power amps, it's easier to route two 4 AWG wires than it is one 2 or 0 AWG wire. Both "+" will go to your battery (through a fuse block, of course) and both "-" will go to a grounding point.

Amp problem


you either have a bad ground or your power line is too small, the farther you go from the battery the larger wire you need.
