SOURCE: Changed battery cable now radio will not even come on.

When you said inline fuse I get the idea that this is not the original radio. Do you have power on the inline fuse? The 50 amp fuse you checked is a bit much for a radio. There may be a smaller fuse in another fuse area of what car type you have. If you do not have power at the inline fuse find some where you do have power (12vdc) and connect to it. If you have power at the in line fuse check the ground wire. If you have a test light or someway of checking for power test all fuses everywhere. If you have a fuse location guide for this vehicle look for the fuse for radio. If it was a add on or after market radio they probably caught power from the original source That is fused under the dash.

SOURCE: Pioneer 12v car amp rated at 1200 watts max requires ? amp fuse

Hi I would suggest 40A (i know guys will disagree) but you shouldnt be running at full 50A. Fuse are often rate at 50% - 75% of the actual consumption. By the way, 8 guage @40A will give you about a 2% drop at 5 feet. Maybe consider heavier for 40A?? Just a suggestion

Audio baha A6601T What size power cable?


First, you need to know how far the battery is from the amplifier. In DC power systems, size IS important. The further the distance, the more power will be lost in a cable of the same size.

I use #6 wire for both the Positive and Negative terminals for powering a 100A continuous draw over about a 15 foot run. The wire does get a bit warm, so it is probably a bit small for the service I am using it in, which isn't critical. You may need to use #4 wire, but I doubt it. Audio amplifiers have a low continuous power draw, compared to my application, and although I have seen some fused at over 100A, the chances are that this is on ly in case the amplifier shorts internally. I doubt if the amplifer fused at this level has ever drawn more than 50% of this rating.

#6 wire can be purchased from a welding supply or automotive store. A typical price is about $1.29 per foot. Get crimp on connectors for the cable, don't try to actually attach the stranded wire to ANYTHING. You'll just have problems. Also, ask the store if they can actually crimp the connectors to the cable for you, although you would need to have the exact measurements for the cable. Remenmber, any excess wire length is a loss of of power X2, as you have 2 wires to contend with. DON'T count on the vehicle chassis ground to supply a good negative ground. Run both the POSITIVE and NEGATIVE wires striaht to the battery. It is also important to put a fuse (100 or 150A) at the battery POSTIVE terminal to prevent the possibility of an electrical fire if the positive lead gets cut and shorts to the chassis.

Blew a fuse installing radio. Now, van won't start???


Unfortunately some vehicles use the same fuse for ignition and non- critical electrical devices such as the cigarette lighter, interior lighting trunk opener solenoid etc... It could also be that the power supply wire (red) for the radio is double tapped to a fuse that is dedicated to any number of components and if it is interrupted (blown) the vehicle won't start or even crank. Another possibility is the vehicles computer detected a short or high amp draw and disabled the ignition to avoid fire or further electrical system damage.

The radio/player power line should be properly fuse protected for the highest amperage that the radio/player may draw when it is at maximum wattage, meaning CRANKED UP! It must be connected to the positive cable coming from the battery, safely away from the battery using a properly rated power terminal or power bar that is covered and sealed. It must be securely mounted, grounded and in an area that is clear of anything under the hood . This requires cutting the positive cable, putting connectors on each side of the cut cable and connecting them along with the player and power amplifier power line(s) to the new power terminal.

DO NOT CONNECT THE PLAYER LINE DIRECTLY TO THE BATTERY TERMINAL! The power line wiring for the player at max. volume MUST be of the correct amp rated gauge. You may also need to get a higher amp battery and a higher gauge battery cable to handle the power draw. It is also CRITICAL that every entertainment system component is SECURELY grounded with the right gauge ground wire to metal that is part of the vehicles frame. Failure to do this on a high amp system will toast your vehicles entire electrical system, (very costly mistake) also use dielectric grease on all electrical connections to maintain the integrity of all connections. I may have given you too much info, Good luck!

How do you install the hk-401sx amplifier?


A 4 Gauge or even better a 2 Gauge power cable Starting from the Battery going thru a fuse block which should not be more than 12 inches away from the battery then to the battery connection on your amplifier the states 12V. A similar gauge cable connected from the GND negative (minus) of the amplifier to a good clean and cleared of paint location on the chassis somewhere in the boot (secure well) A cable connected form the blue and white cable at the back of your head unit to the remote input of your amplifier which is next to the speaker outputs on your amplifier and clearly indicates REMOTE. A stereo RCA interconnect from the output of your head unit to the line in of your amplifier. Best if there is a dedicated sub woofer output. You then connect your sub woofer. dreamsystems

About Power supply wires (MRP-M1000 only)

• 21mm2 is the minimum power and ground cable size

that should be used to connect this amplifier. The

length of these cables should not exceed 1m to assure

safe operation.

• If the length of the power and ground cables exceed

1m, or if you connect more than one amplifier, a distribution

block should be used with 33mm2 or 53mm2

power and ground cables depending on the length

necessary. Ensure that you install a correctly-rated

in-line fuse on the power cable near the battery positive

I dont know why my amp is not getting any power? the power light wont even come on? everything seems to be connected properly, but its not getting any power?


Make sure you have both power wires hooked up. There's the main power lead/cable going to to the battery, and the trigger wire from the accessory wire from the radio (antenna) to the amplifier. Hope that's what you were looking for. If so please rate my assistance and leave a testimonial.

My battery was dead of a week. When I purchased a new one my radio would start but only the head unit would power up. I went back to check the amp and its not powering on. I believe its the amp but don't...


Walmart, K Mart, Auto shops, car stereo shops would be a great place to start to search for fuses. Make sure you take out the old one from the amp, and I would also take out the fuse from the battery compartment as well. Do not buy bigger rated fuses, make sure they match the ones from your amp!

Blowing both amp fuses


Then you must have a short somewhere , either your main power cable has a pinch or short somewhere , it is not correctly installed , your blue or amp turn on wire has a short, the vehicles battery has problems or a charging problem from the cars alternator. Try all of these.buy a cheap test light at an Autozone or Pepboys put the grounding clip to a 12+ Volts source and put the test light tip to the red power cable that powers up the amp, if the test light bulb turns on then you have a short somewhere and you would have to trace the cable from battery connection to the amp connection for any accidental grounding or pinch wire.

Good luck.

Good luck.

Won't turn on & don't know how to hook up to a 1963 pickup.


Don't get confused, it's very simple. +12v----direct supply from battery.
REM---also 12+ supplied from igntion switch. (when the key is turned on, this supply should have 12+ to on the amplifier.
GND--12- minus (negative)
Try it you will be able to set this up. REM can also be used with a single switch which can break the 12+ when amplifer is not in use, or else this will take all ur power battery. You can place a fuse on 12+. Thanks

Green light is off and red prt light flashes once I have a crossfire 1000WT


Most likely you need to check the Fuse(s) and check all connections including any RCA's and Speaker Wire. Do that and get back to me.


Thank you for using Fix Ya!
Good Luck!
