Installing Two Amplifiers - Can I get MORE BASS?For instance, if you have a watt total 4 channel amp and a watt subwoofer amplifier, you would need 2 gauge feed into a distribution block to be able to support the two loads. And, As for the ground, you can just bolt up both of the grounds to the same location without worry, assuming the ground is on straight metal on the frame of the car. But be sure to leave a very good ground connection. A good car amp grounding is very important in order to avoid amp starvation. Or, you can use a ground block connected to the car body, with the two cables that come from the amps connected to it.
Read the documentation for the head unit and determine the type and number of RCA outputs available at the rear of the device. Certain head units may include one or several RCA outputs, providing separate signals for the front and rear speaker channels, while a third subwoofer channel will handle low frequency sounds.
Can You Wire in Multiple Amps or Are You Limited to Just One?
Remove the bezel surrounding the head unit faceplate to expose the removal key slots, if applicable. Refer to the installation and removal instructions for the head unit for specific guidelines needed to slide the unit out from the mounting chassis.
Insert the specially designed removal keys into the removal key slots, found near the left and right side edges of the head unit. Slide the head unit out of the chassis to expose the available rear RCA output connections. Disconnect the antenna cable and main wiring harness from the rear of the head unit. Place the head unit in a safe area.
Determine the wiring path for the power cable leading to the external amplifiers. Typically, power cables run from the battery, through the vehicle's firewall, underneath the left or right side interior rocker trim molding and carpet.
Never run the RCA audio cables together with the amplifier power cable; run the RCA cables underneath the opposing side of the vehicle. Refer to a vehicle specific repair manual for instructions related to interior trim components and bottom dash cover removal, if necessary. Remove the left or right side rocker trim molding and lower dash cover located inside the vehicle, using an appropriate size screwdriver. Remove the top and bottom rear seat cushions to gain better access when running the RCA cables to the rear trunk area, if applicable.
Installing and connecting multiple car audio amplifiers into your vehicle will allow you to improve sound system quality and connect additional speakers, or make. I'd like to hook up a second amplifier for the rear 2 speakers and the left What can I use two bridge these two amps together into 1 cohesive. Close up of car speaker through a fish eye lens You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra planning.
Label each cable appropriately, according to the channel type, using masking tape and a pen. The short answer is that you can use any number or combination of power amps in a car audio setup as long as you wire them in properly.
Hook up two amps
The main proviso is that the charging system has to be able to provide enough juice in the first place. If you add in too many amps, and they draw too much power, you may need to upgrade your alternator or install a stiffening cap.
The most common reason to wire in multiple amps is to have one for your main speakers and a second amplifier for a subwoofer. If you do decide to go with multiple amps, the process of multi-amp wiring is similar to single amp setups.
In terms of amp wiring, that means getting your power straight from the battery.
With that in mind, you have the option to either run separate power cables for each amp, or a single cable that feeds all of them. Depending on your particular setup, either one of these options may work out for the best. In most cases, a single power cable is the most elegant solution. Due to the fact that your power cable needs to handle the current draw from all of your amps at once, it needs to be significantly larger in gauge than called for by the specs of your individual amps.
For instance, if you have a watt total 4 channel amp and a watt subwoofer amplifier, you would need 2 gauge feed into a distribution block to be able to support the two loads.

Recommendations for connecting two amps for surround sound
The capacitor is not needed. It does very little unless you spend a lot of money in a very fast cap and the results are still questionable. People use it due to misinformation, and because, if well done, it can look cool.
Just remember to fuse everything.
From an engineering point of view, use automotive grade wire of an appropriate gauge. The amps should reject power-borne interference so there should be no problem in running two amps on one circuit. Either use the gauge and fusing recommended by the amp manufacturer, adding the gauges by summing the cross-sectional areas or current capacity to find the combined gauge, or start from first principles by looking at the minimum supply voltage in the amp spec and the length of cable run and current draw to calculate an allowed voltage drop, maximum cable resistance and hence wire gauge.How To Hook Up More Then 1 Amp
You might consider adding a supercapacitor close to the amps to provide power for sudden transients, in which case you could use a thinner gauge of wiring.
