Ive recently had my sub woofer un secured banging about in my boot, and it finally caught up with me, it endid up slamming into my amop and breaking the RCA's leaving them breaking inside the imput plugs, so what id like to know is would this be easily fixable, and would i risk damaging the amp by taking it apart, as well as is it possible to connect new RCA heads to the existing cable? (Dont wana rewire it again :P) Any help would be greatly appreciated Cheers Hamish

Hi, I went to the Denon website and they have no documentation there for your receiver. But do not frown, I have some good suggestions for you. 0 Don't beat the dog. After all, it's their job to chew things. 1 Get a new, un-chewed cable and see what happens between the sub output and the sub woofer. If it works, your in business. If it does not work. Don't be discouraged . Go to step #2 2 If the sub output on the Denon has failed, and everything else is good. There is another way to use your sub. Install a patch system using the Headphone output from the front of the Denon. It may seem odd, but it works exceptionally well for the following reasons. It works on all signal sources. So if you are not playing a home theater source, you still have the use of your sub. You will need the following adapters. 1 A Male stereo phone jack to female mini-phone jack. (Something that would accept typical small headphone sets such as those on an iphone). 2 A stereo "Y" connector that that has a single stereo male mini-phone jack that has two "RCA" female jacks. 3 A simple RCA male to male stereo cable pair as is commonly used to connect CD players, etc. i.e. separate red and white RCA connectors at both ends. 1 and 2 above may be available as a single unit combined with each other. Take these adapters and connect the Item 1 into the Receiver, Item 2 plugged into Item 1, Item 3 plugged into Item 2 and finally the other end of Item 3 plugged into the two female RCA jacks mounted onto the back of the sub-woofer. If the sub only has one female RCA connector, get a RCA "Y" connector that has a single male end to 2 female ends. This setup will work perfectly with any sub. The reason is as follows. Most decent subs have an adjustable high frequency cut off. So you can vary it from about 20Hz up to about 140 Hz. I recommend that it is cut off at 80 hz. This way the bass transition is usually seamless between the woofer and the rest of the system. . Then adjust the woofer volume control in a similar manner. If it all works out, give the dog a treat and enjoy yourself. I really hope this helps, I love my sub woofer as well. Let me know how this turns out. If you have any questions please post them on the site and I'll get back to you ASAP. Best Regards, Mark
You will need an amplifier or 2 channel receiver. Hook the sub out rca jack to the rca inputs on this new amp or receiver and hook the speaker terminals on sub to speaker terminals on same amp or receiver. Your Yamaha receiver doesn't have any power for a passive sub.Just pick up any old fairly high powered receiver for fifty dollars and you're good to go.I use old dolby pro logic receivers as they are a dime a dozen today. Good luck.
Try using front pre out to the sub from the receiver. the crossover is in the sub anyway. If this works change your settings on the receiver and test again. If sub is still inop, could be an internal issue with the sub amp. Does your sub amp have an on/auto/off switch or light? check that as well. Hope this helps, if you need further assistance, send a reply and I'll help some more
did you plug your rca signal wires into the subwoofer ouput rca's? if so you can control the level and frequency of the sub on the face in the audio menu. if this is not the issue try new rca cables. you can run them outside the car first just to test. another issue is make sure you have proper grounding on the head unit and amp. also if your rca cables acccidently touch power they can blow a fuse or trace inside the radio causing the rca's to lose ground (you will have low audio with lots of humming noise). you can check this by jumpering a small wire from the radio frame to the outer shield of the rca jack while it is all plugged in. if the sound gets louder and cleaner you can secure this wire in place by soldering it or fixing the circuit board itself.
In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs. Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.
Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.
