I have read a number of the posts here regarding different stereo options. I've seen a general consensus that the Soundstream pn4.520 is the best bang for the buck 4 channel amp on the market. I've also seen a general preference for the Polk MM651 speakers both in the fairing and in the tour pak pods with the crossovers mounted under the passenger pad. These are both options I am seriously considering, however I have a somewhat specific goal that I've been unable to find a good answer to and was hoping some of the audio pros here might be able to help.

I have a 2006 Ultra with the stock stereo that I would like to keep in order to retain CB radio and intercom functionality. Because of this I am mainly looking to upgrade speakers and amp for now. I am working toward making the tour pak removable and nearly have all the pieces compiled to complete this goal. What I would like to do is design a system with good fairing speakers and add some speakers to the lower fairing as well. However, I'd like to do something with the tour pak speakers as well for when it is on, but I'm not sure how I'd power these if I were to use the pn4.520 amp and if it was run off one of the other channels, what would the detrimental effects be to the rest of the system when those speakers are on the bike? I'm trying to make a good, doesn't have to be great, budget system that won't distort with the slightest amount of volume and bass like the stock one does.

Thanks in advance for all the help, this forum has so much information that I would have had no clue about otherwise. UltraNutz stereo information here has been spectacular. Having had some familiarity with car stereo equipment in the past, how difficult/involved is the wiring required with the pn4.520 amp being integrated? Also, does this remove the ability to use the stock stereo's AVC function? I've seen that advertised as a benefit to the Hogtunes amps, but I'm unsure if that is even a real consideration.

 

it's always great to have a goal when you start this and your goal is certainly attainable.

What I'd do is the SS PN4.520D amp
Drop in DB651 speakers in the fairing and lowers. These are 4 ohms speakers. Wire each side in parallel to achieve a 2 ohm load the front channel of the amp will see. This is where you'll get the best results as what's in your face is what you're going to hear the most.

The rears, put in a set of MM651 speakers there with some sort of quick disconnect for your plans to make it removable. This will have both front and rear channels driving a 2 ohm load and when you remove the rears, it will have no effect on the front. Just make sure to use some kind of disconnect such as a deutch connector (make it look stock) for the rear speakers so the disconnected wires don't short together or to ground and cause problems with the amp.

The wiring is very straightforward with the amp install. You'll take your front and rear outputs off the radio and run them into the amp, you'll take your front and rear outs of the amp and wire to your speakers. The rear speakers will be the only ones with crossovers as the DB651 speakers do not have these crossovers.

As long as you're staying with the stock radio, none of it's functionality will go away. Everything stays the same. The amps have no effect on the AVC other than amplifying it.

You will need a relocation bracket to relocate the CB module below the radio so you can mount the amp on top of it. Again, very easy to do.

You'll be very happy with this setup.

Here is the wiring diagram from the radio to the amp.

 

This may be a stupid question, but can I still use the standard wires to the rear pods or do I need to run lower gauge wiring to handle the increased power? Also, any recommendations for which lower fairing pods to use? Are the CVO the standards that people have been going with?

 

Part of the reason I ask that last one is because I've got a bunch of deutsch connectors stuff that I was going to use on the stock wiring to make it all quick disconnect, but I'll wait on that if I'm going to be running new wires anyway.

 

The only stupid questions are the ones that don't get asked.

Yes absolutely so use the stock wiring. This is not an audiophile type system where you have to account for every frequency within the spectrum.

From what I see, the CVO pods are the ones most are using but also check out Hawg-Wired for other options with the lowers.

Is this the same for wiring an aftermarket radio?

 

no change in wiring other than using RCA outputs from the aftermarket radio instead of using high level inputs from the stock headunit so the diagram I posted for you won't be used in aftermarket headunit install. Use the RCA outputs..

 

thanks for the reply. you wouldnt happen to know where I should ground this system would you? I am installing the ss amp, sony radio, hawg wired tweeter kit, and some 6.5" speakers

 

when you pull your outer fairing cap off, look just below the stock radio at the front of the triple tree. On the left is a ground lug from HD already attached. To the right is another threaded hole in the triple tree. Use that to ground your system.

 

thank you sir!!
