The car stereo is "off" when i start the engine, and the sub does not even turn on until the stereo starts playing music (the sub detects 'audio' in order to power itself on).
Ground wiringrather than grounding your amps individually, a distribution block should also be used to provide the ground connection.
The gps could run off batteries, but the heated stuff has to run off the bikes power.
The turn-on wire will "tell" your amplifier to turn on whenever the receiver is powered up (usually, whenever the vehicle is turned on).
This technique will work fine in systems with under 75 watts rms of power per channel but for more powerful systems it would be better to run new speaker wire directly from the amp to each speaker.
Installed a powered subwoofer (rockford fosgate p300-10) in my 2014 honda accord, and i hear some humming/rumbling when i start my car engine.
Because of its low current demand, you can connect your turn-on lead to almost any fused output terminal, like the one for the radio itself for instance, as long as it only powers up when the vehicle's on.
Route the patch cables to the opposite side of the vehicle from the power cable.

. after routing the power and signal cables to your chosen location, using the techniques described previously, mount your amplifier in place.
Strip the insulation off the end of the power wire that leads into the passenger compartment, and connect it to the other end of the fuse holder.
And because the distribution-block, and all the accessories, gets power directly from the battery there is very little chance for damage to other electrical components.
Make sure the main power cable is thick enough that it can handle the additional current draw of any amps that you might add in the future.
Run the ground from the negative battery terminal to where you've located your distribution block and connect that black wire to your distribution block.
How to hook up a power distribution block
The relay powers the entire distribution block at once, and then powers it down as soon as you turn your key off, preventing accidental battery discharge.
Speaker-level signals are not very prone to picking up interference, so it's okay to run your speaker wires near power cables.
:the short answer is that you can use any number or combination of power amps so long as you wire them in properlyprovided that your charging system is able to provide enough juice in the first place.
Remove the battery terminal's nut, slip the power cable's ring over the bolt that secures the battery terminal to the battery post, and replace the nut.
If you run any accessories on your bike, including electric gear like heated vests and heated grips, or even toys like gps devices or radar detectors, hooking them up to the bike is always a challenge.
A relay/distribution block typically runs directly off the battery with the relay getting its power from a running light or other switched source.
My name is adam i hooked up a 1300 wat apm to my old mobile alero go and with 1600 watt wires and it keeps kicking off the apm if i turn the bass even up to -3.
Amp wiringregardless of the number of power amps you use in your car audio system, its important that you stick to wiring best practices.

Amp terminal block - 6 position - isolated terminal block is rated for 30 amps per location and up to 600 volts.
, a powered subwoofer sure is more convenient to install than a separate amplifier and sub enclosure, but, except for speaker wiring, you still have to go through all the same installation steps as you would for any other amplifier.
Distribution Blocks for routing and or distributing power circuits in 12 volt and 24 volt electrical systems.
Your relay has a key labeled 87a, that key will always be powered, even with the key off.
, there are a couple versions of the distribution blocks, depending on where your happen to find yours.
A distribution block can also be fused, which is helpful if your amps dont include built-in fuses.
The jumper will connect half of the poles together by fastening it underneath half of the screws on the distribution block, this is so half of your block will be positive and the other half, with the help of the other half of the jumper, will be negative.
, take some red wire and connect it between pin 30 and the positive side of your distribution block.
That your distribution block is active, its just a matter of attaching all of your accessories up.
If your lights dim just a little during heavy bass passages, you might benefit by installing a capacitor on the bass amp's power cable.
Amp terminal block - 12 position - isolated terminal block is rated for 30 amps per location and up to 600 volts.
.using 4gage for main power and ground and 12 gage wire for subs and 14g for speakers?
Most guides do recommend running the power and signal wiring along opposite sides of a vehicle to avoid induced interference, although many people run them together with no problem.
, with the main fuse by the battery and each amplifier having its own onboard fuses, you'll be okay using an unfused distribution block.
. the power wire from your amp wiring kit (usually 16-20 feet in length) needs to run from the battery, through your car's firewall, through the car's body, usually down the driver's side, and on to the amp.
Can i hook up two amps, or even more, or am i better off with a single one?
Gauge power distribution block - this power distribution block accepts up to a 4 gauge power cable for the input, and distributes that power out to 4 separate outputs that each accept up to a.
. attach the power cable to the positive battery terminal (not directly to the battery post itself).
Stud junction block - power studs are a plated copper alloy for high conductivity with a stud size of 3/8.
What size power wiring kit to use will be specified in your amp's owner's manual.
Point power distribution block - main power stud distributes out to 8, #8 screws for sending power to individual circuits.
You can also connect a forked plug onto the other side to interface with the distribution block, but i simply bared enough wire to wrap around the screw post and soldered the bared wire to prevent fraying, for the same basic result.
I just got a 5 channel amp and want to hook this up and read that running new dedicated speaker wires would be the best thing to do.
