Active Crossovers Installing an active crossover requires a bit more work. Is the mixer stereo, and are there 2 cables going to the crossover inputs? This type of system has very little chance of sounding good. The relative output levels of the high and low frequency speakers would again be adjustable through the fader control of the head unit. My only suggestion to achieve what you are wanting, is to use a two zone speaker selector switch with volume controls. If you can't locate it, check your instruction manual.
At the beginning of the this process, make sure the input gain on your crossover is turned all the way down if it has an input gain knob , set your amplifier gains low, and if you have an equalizer, turn it off or set the levels all flat. The impedance of the speakers should be written on the back of the speaker or speaker box. Finding the right spot You'll want to put your crossover in a location that won't take up too much space in your vehicle, but is accessible enough for you to be able to make adjustments. The rear outputs go to the amplifier which drives the speakers in the rear deck. This diagram shows how you'd connect 2 amplifiers if the amplifiers had internal crossovers. Both the theory and practical points on how to connect 2 speakers are discussed.
I took courses in radio and electronics as a teenager, and became a ham radio operator. I understand presently ignoring speaker sensitivity that my 75W per channel wired these two speakers in series gives me 27. Tools and Materials Needed: Active car audio crossover Screws Screw drivers 12v wire 18-gauge wire 2 pcs. This may require a crimp-on connector, or bare wire might be sufficient, depending on the equipment you're installing. You may also find an answer in the questions and answers below. Remove the receiver from the dash to access the turn-on wire usually a blue wire. Note the crossover settings on each of the amplifiers.
The added amplifier and other electronics in an active sub add a bit of weight and cost over passives, but not having to add another power amp to your rig often more than makes up for the expense. For example, a woofer might play from 20 to 3,000 hertz, with the tweeter playing from 3,000 to 22,000 hertz. You should mount it where it will be easy to get to so that you can make adjustments without too much trouble. If the factory speaker had a spacer for window clearance, slide that over the back of the speaker first. A distribution block is a good way to get power for your crossover via the same main power cable as the amp uses. If you can, we absolutely recommend you upgrade your operating system to a newer version. When the switch is in the 4 channel position, all 4 channels have to be driven seperately and are independent of each other.

Developing this website and answering the questions and comments requires a lot of time and effort. Their toll-free number is on your invoice. If you do wire your components the way you describe, the tweeter will operate normally, as it would still get its signal from the high out of the crossover, but the woofer would play both low and high notes, inefficiently duplicating some of the tweeter's notes making a shrill mess. This is especially true if you plan on using individual amplifiers to drive specific speakers, such as your woofers or tweeters.
It's generally, but not always, easier to use the crossover's level controls. The crossover then distributes filtered frequencies to various speakers or speaker drivers in a system. The amps will always be in stereo. Anywhere between the receiver and the amp is fine. For home amplifiers this number usually starts with 8 ohms.
Component speakers are normally placed at the top of any car audio manufacturer's line. Thanks in advance Hi Todd, You seem to have sorted it out. This section will hopefully clear up any misconceptions or confusion about multi-channel amplifiers in general. Low pass crossovers for woofers require very large inductors. If you bought your gear from Crutchfield, you could call Tech Support for free help troubleshooting your system. Use only unshielded speaker cables for speaker connections. Cut a length of speaker wire long enough to reach to the factory tweeter mounting spot, typically behind the A-pillar.
In this type of system, the relative output levels would have to be set with the gain controls on the amplifier. Depending on your setup, this means your crossover could be wired directly between your amplifier and your speakers, or the crossover could be placed in line after a compressor or equalizer. Whether 2 speakers connected to one amplifier should be in series or parallel mostly depends on the impedance of the speakers. More than happy to help those who at least attempt to help themselves. This diagram shows the rear channels bridged. Still, it can be done. Offering increased placement flexibility over conventional coaxial units, component speakers anchor the front soundstage of any serious car audio system.
This can also include any crossovers and circuits connected to the speakers. If you do not plan to adjust it much after initial install, keeping the crossover behind the dash panels is a good option. Plug the speaker cable into the low frequency amplifier's speaker output jack, and the other end into the low frequency bass speaker input jack. This is the resistance impedance presented by the speakers that is seen by the amplifier. Set the crossover high and low frequency filters according to your crossover and speaker manual's recommendations. Attach your speakers to the crossover using speaker wire, similarly to the previous step. On most crossovers, the fader will still operate through the crossover which would allow you to balance the levels of the front and rear speakers from the head unit.
