I have a panasonic active subwoofer left over from an old dvd and surround sound set. I'd like to hook it into an amp that runs my gaming system sound. It has a 13 over 12 pin female input socket. Any ideas or should i just scrap it?

Re: Panasonic active subwoofer
No way to connect it to your gaming system, unless you are good at rewiring things and even then it may not work right. It would be a tough job, but if you give me the model number I could send you the pinout of the din plug jack. You would then need a male din cable to connect into it and try to figure out which color wire goes to which pin. It can be done, but not to easy. You can't connect it to an amp, it has an amp in it. you would need to use it as your amp. Or just remove the amp section and go right into the speaker wires that plug into the amp board of the panasonic. If you want that information put your email address in the next post with the model of the sub-woofer.I will email what I have on it.
If I were you, I would sell it on ebay before trashing it. There may be somebody who needs one just like it. It can be used with a couple of different Panasonic models probably.

short answer.....no. If you hook more than one speaker up to a single channel, it will lower the impedence and will damage the amp. You can hook up multiple speakers by using a speaker switch box between the speakers and the amp. This will match the impedence and should keep the amp from blowing.
The HTR-420 has only a single subwoofer output. It is the socket on the lower left corner. The other subwoofer socket is part of the multi-channel input.
Because of the age of the 420, it comes from a time when optical and coax connections were not so common and DVD players had 6x phono/RCA sockets to send out the surround signal in analogue format. The multichannel input is for sending a signal in to the amp, and not for getting a signal out. That's why the sub doesn't get a signal from that socket. Use the proper subwoofer out. That's what it is there for.
The 420 was designed to run Speakers A+B together if required. However, you must observe the minimum impedance loading if you connect up two sets of front speakers and run them simultaneously.
The minimum Impedance for each set of front speakers is 8 Ohms. If you're recycling old surround speakers from a Home-Theater-in-a-Box system, or the speakers have no labels for impedance on the backs then you can be fairly sure they are not 8 Ohm. That could be the problem.
1. Connect cable to cable HD DVR box, connect video out of cable box to Sony receiver TV video in, connect audio L and R out of cable box to Sony receiver TV audio in and connect TV out of receiver to video in of Panasonic projector
2. Connect Audio and Video out of DVD player respectively to DVD in of receiver. Good Luck :)
First enable the surround sound mode for the selected input and verify that the media playing is recorded in some mode of surround sound.
You can however, acheive surround sound from 2 channel sources with dolby prologic or prologicII sound processing, or other proprietary modes that your receiver might have from the manufacturer.
hook your front speaker wires up to the A side and on the front of it make sure only the A speakers are playing but leave the rear speakers plugged into the B side then hit the listen mode button and you should be rocking
the difference is the "same speaker connections"
the front and rear will connect the same but the subwoofer is amplified by the HT75 , and the HE75 does not have an internal amp for the subwoofer speaker , only a "pre output"(has to be amplified)
Several things could cause this, to make sure the sub woofer is working at all disconnect the cable from the back of the receiver. You should hear some sort of output from the subwoofer when you handle the plug. IF so replace the plud and go into your settings menu (press the A and B button at the same time) and go through the speaker set up. It may be that the receiver has not retained the memory that there is a sub woofer connected.
The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.
Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.
You can even now turn off your subwoofer / adjust the volume easily now!
