As these components age the current draw can be even higher. If this current draw exceeds the rating of the head unit the circuit can burn out completely. Topics range from basic system installation head units, amplifiers, speakers, etc.
Let me share my thoughts on the topic of installing multiple amplifiers. Most electronic components such as amplifiers, active crossovers and equalizers need about mA to turn on. Reinstall the head unit into the mounting chassis and replace the trim bezel.
This can help lower the noise of the system. This prevents your head unit from trying to deliver too much current which can burn out the turn on circuitry in the head unit. Never run the RCA audio cables together with the amplifier power cable; run the RCA cables underneath the opposing side of the vehicle.
If the head unit does not include a subwoofer output, you may use an available "Rear" or "Front" output as a substitute. I could go into all of the scientific reasons for this but it all boils down to noise. Terminal 85 is connected to ground and terminal 86 is connected to the remote turn on lead from the head unit.
If you are using a filtered output make sure that it is adjustable or that it is at least at a useable frequency for your system design. The drawback is that the signal voltage is also split so that each component is now getting a smaller low level signal which may increase the noise in the system.
How do you split the low level signal? Place the head unit in a safe area.
The price difference between two wire gauges i. I prefer to use a regular distribution block, not the fused type. Preparation Turn off the vehicle and open the hood.
In my experience you have less chance for noise when you separate ground points as compared to using a single ground point. Run the RCA cables through an available wire loom opening that leads to the trunk area, if applicable.
Installing Multiple Amplifiers There seems to be some confusion when it comes to installing more than one amplifier. Most 12 volt relays can supply up to 30 amps of current which is more than enough for all your turn on circuits.
The relay will then connect the 12 volt signal to the amplifiers and other components. Disconnect the antenna cable and main wiring harness from the rear of the head unit. If you do not use a distribution block then you will want to stack your ground wires so that the largest current carrying wire usually from your largest amplifier is on the bottom closest to the ground point and that your smallest current carrying wire is on the top closest to the head of your grounding screw.
If your head unit is lacking these extra outputs then there are several other options. Terminal 87 of the relay is connected to the electronic components remote turn on terminal.
Sub-bass frequencies would be sent to the subwoofer amplifier and high pass signals would be passed to the other amplifiers. Should you use one power wire or multiple wires? This assumes your amplifiers already have built in fuses that are designed to protect them.
Terminal 30 of the relay is then connected to 12 volts. The least desirable method is the RCA cable Y adapter or splitter. If your amplifiers will be powering dissimilar speakers subs, mids, tweeters, etc.
Instead of connecting each component directly you will want to use a relay. Some amplifiers will have an RCA pass through circuit which can be used to drive another amplifier in the system.Installing Multiple Amplifiers.
There seems to be some confusion when it comes to installing more than one amplifier. Should you use one power wire or multiple wires? Do you ground everything to the same point? Most 12 volt relays can supply up to 30 amps of current which is more than enough for all your turn on circuits. This prevents.
People with many components and wires running through their car can easily end up getting "ground noise," which is the whining sound that plays through your speakers and rises and falls with the rev of your engine%(15).
How do I Connect Multiple Speakers to my HiFi Amplifier. Power= watts Impedance (resistance) = 4 ohms Voltage = 20 volts Current = 5 amps. As you know, not being technically savvy I had no idea what to do or use. to hook up my TV, DVR, and VCR. With your kind patience and explanations via emails back and forth I was able to.
Question: Can I wire up multiple amps, or am I limited to just one?
I’m thinking about upgrading my car audio system, but I’m a little fuzzy on amp wiring. Can I hook up two amps, or even more, or am I better off with a single one?
I’m also curious about the best way to wire two amps in if I. Oct 26, · Power amps,and speakers how do you hook up multiple amps to run 8 speakers on my pa system? i have to power amps 1 is 2, watts and the othere is watts i have a crate 16 channel mixer i want to run all 6 speakers using 2 power amps so i dont over load 1 power amp how do i Status: Resolved.
Installing and connecting multiple car audio amplifiers into your vehicle will allow you to improve sound system quality and connect additional speakers, or make better use of high-power after-market components.
