Well I know this is for car audio, but maybe someone knows. I replaced my kenwood 10" Sub. From my 5.1 surround sound system. The Kenwood receiver doesn't have a sub output. So I have it hooked up bridged to one set of the speakers. Is their a way for me to make the sub only play bass? and not play everything like voices? Could I use a resistor or something?

If you are talking about bridging the speaker outputs from a home audio receiver, it is not designed for that and will soon fail. I am not sure I completely understand your situation... your home theater subwoofer blew and you want to replace it? ------------- Support the12volt.com

Ok so I guess I will go to radioshack to get a coil. Thanks.
Dyohn. I did replace my sub, the other ones rubber part ripped off. But on my reciever it only has 4 speaker inputs. so on the front speakers I have 2 front speakers and a center channel bridged to it. and for the rear I have 2 rear speakers and the sub bridged to it. It's kinda crappy, but sounds alright. I was just looking for a way to filter the sub,so it only plays bass notes and not high freq.

You meant speaker outputs. The Coil isn't going to help anything. The center speaker you have connected is nothing but another load on channels that cannot be bridged together! Same with the rear, you can't do what you are attempting without blowing up something. You need a proper 5.1 surround receiver to accomplish your goal.
with the ID as "audioinstaller3" you should know this.

"well it could be "commercial_airport_PA_audioinstaller3"... or "windows_mediaplayer_audioinstaller3"
Even if he was an ""commercial_airport_PA_audioinstaller3be " this would still be need to know info.
Read his other posts, it will make sense.

Well Megaman, in audioinstaller's own words:
I'm an experienced installer in the Brandon Fl area. I've done everything, mostly alarms, amps, subs, spkrs, cd players, dvd in dash and overhead, even tint.

I didn't say I was a home audio expert. I really just wondered if their was a way to set up the sub to only play bass in my home theater system. I will find a way, even if you guys don't know how. So thanks for the smart remarks.

I highly recommend not using your receiver that way as it is not designed for that. It sounds like a 4-channel stereo receiver, not one designed for home theater. Pick up a cheap 5.1 HT receiver and you will be much happier with the results. As for the subwoofer, just like in car audio the sub needs its own amplifier. ------------- Support the12volt.com

The "smart remarks" are because you set yourself up for them. With your user name and professed experience, you should know the answers to your questions already. The science behind amplifiers and speakers work the same way whether they are home audio or car audio, and you are asking some very basic questions.. ------------- Support the12volt.com

Ok thanks for the help guys. I guess you're right. I did set myself up for it. I would have made the same remarks to someone else probably too. It's all good. This is a great site, and a lot of good knowledge and knowledgeable people on it.

Ok so they make bass blockers and capacitors to work with tweeters. Allowing you to hook up a tweeter to a amplified system. So why don't they make something to make a low pass filter for my home audio subwoofer? I know resistors wouldn't work...I need something to block out all the high freqs above 80hz. Any ideas?

wow.....  If you were a doctor I think you'd be askin' "so, ....I cut with the sharp end right?" I guess I should ask just how MUCH experience do you have with any type of audio? Just like stated above, you are asking the most basic questions, that ANY audio installer should know if you've done ANY type of professional installation. https://www.the12volt.com/caraudio/crosscalc.asp#cc ....just to answer your question. BTW, if you are new to the world, fess up, it's not uncool to be new and want to learn. It IS uncool to be new and try to play like you're experienced. With this bunch you're gonna be made out faster than this post comes up.

what you want is a plate amplifier if you dont have a subwoofer that came with one (an active subwoofer.)
I have one of these for a subwoofer i made for HT a long time ago.

mine had some custom tweaks that this guy made, and I can personally vouch for the quality of these units as well as the utterly amazing customer service of this company.
this amp and the right sub will put an earthquake in your chest.
hook up is simple, wire to your speaker terminals, this has xover and stuff built in, so it will only play bass and its adjustable.

The "3" in the user name must refer to how many seconds he's been in the business. It's called a low-pass crossover. Almost every subwoofer amplifier has one. ------------- Support the12volt.com
