NEED TO CONNECT 2 AMPS TO ONE SUB, NEED IMMIDIATE HELP!!!
Apr 25 Posts: You should NEVER attach two amp outputs together , EVER , The voltages will feed back and blow the outputs in a few seconds… Certain competition amps can be daisy chained meaning the output of one feeds the input of the next but thats very few amps that can do that … If you have multiple subs and the amps can run them singly then thats the best route. Jan 21 Posts: Yeah, unless your model amplifier can be strapped and those that can be strapped usually have master and slave controls on them.

This is how a friend has his 18 woofer hooked up.

But the amps I have are 2 channel and each amp has an input and output for left and right channels.

People have told me that I can connect the RCA's from the reciever to the first amps input and connect another set of RCA's from the first amps output to the second amps input and then from their connect the speaker wire, bridged from the second amp to the box. If the HU's fader is turned toward the rear amplified speakers, you may get better sound quality or at least less clipping from the internal amplifier but the image will be from the rear of the vehicle which is generally undesirable.
Many people run tweeters from the internal amplifier but this also generally leads to less than optimum sound quality. Not because the internal amplifier is of poor quality but because it will be driven into clipping if the output of the tweeters is to keep up with the speakers which are driven by the external amplifier. Since most amplifier are capable of driving 2 pairs of speakers, I would strongly recommend driving all of the speakers from the external amplifier.

If the amplifier has a built in crossover, you'd set the crossover for low pass and probably to about 90 or hertz if there's a choice. You still won't be able to get very high SPL before the HU's internal is driven into clipping but if you only need to pick up the bottom octave or so of the audio spectrum, this may do a good job.
This diagram shows how you'd connect 2 amplifiers if the amplifiers had internal crossovers. You would set the crossover on the top amplifier to high pass and the crossover on the bottom amplifier to low pass.

You could adjust the levels of each amplifier by using the HU's fader control or with the gain controls on the individual amplifiers. In this diagram, we are using an external crossover.
It's generally, but not always, easier to use the crossover's level controls. In this configuration, since we are using a single set of RCA cables, you'd have no control over the levels of each amplifier from the head unit. Some crossovers have a third input which would allow you to connect the other set of RCA outputs from the head unit to the crossover into a subwoofer input jack.
imbalsamarebraila.ro/wp-content/mejores-web/4051.php This would allow you use the fader to adjust the levels between amplifiers. In this diagram we see that we have a seperate amplifier for the front, rear and low frequency speakers. The RCA patch cables go to the front and rear inputs of the crossover. The front outputs of the crossover go to the amplifier which drives the front speakers.
The rear outputs go to the amplifier which drives the speakers in the rear deck. The crossover's subwoofer output goes to the subwoofer amplifier.
