I am about to hook up the Pyle plg6c with passive crossovers and would like to know if I need an amp to connect it,thank you

It depends on your stereo you have installed. Some come with a good amp attached and others do not. I have a factory AC delco and it pushes them just fine. so the answer to that would be based on what stereo you have installed.

Hope that helps.

first, you will need a passive crossover, i do not believe that the mono out of the mixer has a crossover., if the amp does not have a crossover. you could use the "mono" output, and split the signal, with an adapter, to both channels of the crossover, then run both of the low outs to the 2 channels of the amp. or, you could hook the crossover to the main laft and right outputs of the board. send the 2 low outs, left and right, to the subs' amp, and send the two high outs, left and right, to the main speakers' amp.

Here is a link to the manual:http://www.peavey.com/assets/literature/manuals/00513220_7.pdf I didn't look at the manual for the crossover but this is probably the way I would do it. Look at page 13 in the manual : Come out of the Main out (31 in the diagram) into the main in of your crossover. Go out of your crossover Hi and Mid out setting back into Power amp In 1 (labelled 32 in the diagram). Hook your speakers that you normally use to the output jacks on the back of the Peavey. Make sure you match the output impedances. Go out of your crossover low output into the Pyle power amp and out of the Pyle into your subs. Make sure the impedance ratings of all your speakers match the output impedances of your amps. You will only be running in Mono mode as that is the signal output of the Peavey mixer. You can run faux stereo by using the Main monitor Out as 1/2 the pair and the Main Out as the other 1/2 to both channels of the crossover but you won't be getting a true stereo pan mode.

you dont have to have a crossover to hook up ur amp 2 ur subs

Line outs Left and Right from mixer to power amp Left and Right inputs,
Power amp outs to Subs(if they have passive crossovers built in check specs on subs).
From Subs then to Main spkrs. Make sure power amp is set in stereo mode using this way.

Alternative: You will need at least a 2-way stereo crossover unit inline after mixer and before power amps if the subs don't have a built in passive crossover. Most of them do have passive crossovers in the subs these days. Then separate amps or one channel would drive the subs and the other the main speakers. True stereo would require at least a 2 way crossover and two stereo power amps if hooking them up this way.

There is another option as is common with many sub setups. Send the signal to the mains using L/R outputs from mixer and a separate Mono output to the subs only. Putting only bass/kick and low frequency outputs in this send would help too.

try this site to see if it's for your model, but if not it should still give you the basics for installation. Now for the crossovers, if they are passive they will go between your head unit and amps or speakers. if you can tell me the make and model of the crossovers, i can tell you exactly how to hook them up. Let me know if this helps :)

I'm purchasing 2 infinity 3-way passive crossovers on eBay with the same crossover freqs as my two overture 3's with blown amps. For 19.99 each, it's worth a try. Good luck to you!

you should be able to remove the passive in-line crossover, but since it is blocking everything below 3500 hz, there is no need. leaving the passive crossover in place will also help protect the tweeters if something fails in your setup as any amped frequency below 3500 can seriously damage them.

You didn't say if it was active or passive, but here is both:

Passive crossovers are easy to install. By definition, the only type of connections they require are to your speaker line. They typically get installed between the end of the speaker wire and the speaker. Connection should be fairly simple, just like hooking up the speaker itself.

Now F-Mod crossovers modify the audio signal before it is amplified. They accept the patch cord from your receiver on one end, and then plug directly into the preamp inputs on your amplifier. They are also easy to install, and don't require additional wiring.

 An active crossover requires a little more work. You have to connect 12-volt power, ground, and a turn-on lead. The active crossover gets installed between your receiver and your amplifier. A lot of active crossovers have both speaker-level and preamp inputs, so they can usually work with either type of connection. The outputs will be preamp connections to your amplifier. Hope that helps.
