If you're connecting two different systems to the sub one to low and one to high level inputs then you should also be fine, but again if you only have one crossover on the sub which applies to both inputs you have to do a lot more manual fiddling. Apr 17, 2008 I believe that this model Sony amp includes High Level inputs. Or they could be spring clips like you'd see on the back of standard speakers. You'll also route your red power and blue turn-on wires under door panels or under seats to your amplifier. The P300X2 is a solid choice if you're looking to drive a pair of coaxial speakers, component speakers, or a single subwoofer. I ended up running a ignition wire for amp turn on and installing a high level converter, make sure the watts rating is adequate. I'm thinking I might have to get a Line Output Converter that converts High voltage to low voltage so I can use the Low input setting on the amp.
If youre up to the task of assembling one, you have to work with the following four equations, which are used to determine the values of the resistors and the degree of attenuation theyll introduce. This is because, when an amplifier in the radio amplifies audio, it will create a specific amount of distortion. The crossover is used to select the crossover frequency at which the subwoofer will cross into the frequency range of the speakers. There are two main ways I have seen high level connections offered. If your amp is in your trunk, it's a relatively short path to rear deck speakers or a subwoofer. Assuming the speakers impedance is the usual 4 ohms, we can determine the correct resistor value by substituting 0. A High to low level adapter can be purchased at most audio retail or online stores.
Then solder the left negative-input lead ground to Terminals A3 and Bl and the right negative-input lead to Terminals C3 and Dl. But now after doing some reading, some others claim you cant tap into the signal between the headunit and the jbl amp, because the way the system works it will only provide a constant voltage and there wont be any volume adjustment. Do you work in the 12 Volt industry? If your amp only has low level inputs and you want to connect it as explained here you will need to add a line level adaptor before feeding the subwoofer amp. Fader A fader allows you to adjust the balance between front and rear speakers, and its one of the most useful low-level circuits; fortunately, faders are built into most head units. How do you currently have it ran? The gain works the same as for the low level connection, and balances the output of the subwoofer to match the rest of the system. Finally, solder the negative lead running to the amplifier to the open side of R2.
Hopefully it will also resolve some of the confusion as well. Remove rubber strain relief from connector backshell by pulling it out of the backshell. . Tapping into only my 2 rear speakers to pick up the bass and everything worked fine. Also, the capability of controlling the amp with a remote. When I bought my X5 the very first thing I noticed was that, although the audio components were of pretty high quality, there was a definite lack of lower bass.
Typically this is done with a cable that connects to the front left and right speakers. But if key turns off but head unit is still on but then goes off after a few minutes like most vehicles these days do and amp turns off when head unit turns off your good to go. They won't even sell me a couple of feet of 4 gauge wire. Be sure you understand all the connections before you proceed. With the balancer, its simply a matter of rotating a conveniently located pot.
Unlike a power-dropping network, it can be inserted between a passive crossover and the speaker, since it presents a constant input impedance. Please give us more detail. It should work but I got too much noise hiss. Next, solder the positive output lead running to the amp to the junction where the two resistors meet. For example, suppose your head units output voltage is 50 millivolts but the amplifier you want to use requires an input signal of 250 millivolts or more for optimum performance. The blue remote wire should be wired to accessory wire. Note in Figure 5 that each audio signal designated as L+, L-, R+, and R- is connected to separate gangs each gang has three terminals.
Amplifier wiring Click on the link below to continue. Many amps can't handle the high power input from the stereos. The first is via a single input using a Speakon connector. The main speaker channels carry the full audio range. After all, its often such attention to detail that transforms a good system into one that is truly outstanding. Active Low-Level Networks In contrast to passive devices, active networks are relatively complex, powered devices that allow you to cut and boost the amplitude of a low-level signal; due to their complexity, construction details are not provided. Sorry but you can buy pretty much anything online for a cheaper price including shipping if you look hard enough and are willing to wait.
If you have a 2 channels amp instead of a mono amp then verify that it is bridgeable which means that you can bridge the 2 channels into one to feed a subwoofer. The wiring is easy: The pot goes in-line prior to the amplifiers inputs. Installation issues The installation of an amplifier using speaker-level inputs does not differ significantly from one with preamp outputs. Conversely, rotating the shaft counterclockwise moves the wiper toward the negative terminal Terminal 3 and reduces the output level. This will help with distortion rate, however, it will still be there, as the high to low level adapter will try to remove as much distortion as possible. Picture 5 below shows the wiring of this connector.
