Also- Gannicus, how much space did you lose in the TP? And how did you mount that amp in there? Looks like you have a plate that you mounted the amp on, then you bolted through the TP (I'm guessing you drilled new holes, and didn't try to use the small holes for the pouch, correct?).[/quote]



The only space I lost is the depth of the amp. The OL can still put everything in the tour pack she could before I put the amp back there. She was raising hell with me at first until she found out she was good. I did use the holes that hold the pouch to mount the amp. the material you see the amp mounted to is a half inch of plywood from home depot. I mounted the amp by the four feet to the plywood and then mounted the whole thing using the two pouch holes. Amp stays cool as the other side of the pillow back there.

It will work on the stock unit too.

It comes with double sided tape already installed on it.

So I'm set up right now a Sony DSX-310BTX using the preamp outputs to a single Soundstream PN4.520 amp running the following speaker setup:

Biketronics 7.1s in the fairing and Biketronics HAT 6.5s in the lower fairing pods, run in parallel off the front channel of the amp.

Pioneer TS-D1602R 6.5s in the tour pak pods and Pioneer TS-D6902Rs in the Hogtunes Lids run in parallel off the rear channel of the amp. (these speakers are subject to change: I'd ideally like to have Biketronics speakers in both locations; possibly 7.1s in the pods and their 6X9 kit in the lids for better weather resisitance)

My question is this:

What should the wiring setup be to run a second SS amp (or similar 4ch amp) in the tour pak so I can power the back of the bike on it's own amplifier? How do I connect the second amp to the head unit?
Here's what I would do Mike. Use the existing amp to run your front speakers, each to their own channels. You'll need 4 RCA "Y" adapters to accomplish this.
use a Y adapter on the front right output to both right inputs on 1st amp
use a Y adapter on the front left output to both left inputs on 1st amp
use a Y adapter on the rear right output to both right inputs on 2nd amp
use a Y adapter on the rear left output to both left inputs on 2nd amp

absolutely. 10ga power and ground for each amp

I would say that's up to you. Either saddlebag or the tourpak. If your tourpak never comes off, that's where I would put it. Saves you the hassle of disconnecting things when taking saddlebags off. Either location will be fine for the heat issues and that amp is small enough to not lose much bag/pak space.

more power is always best especially with the speaker configuration you're running. You don't know what those 7.1" will do til you put 100w of power on them and you certainly haven't awaken those TSD-6902R speakers with 65w of power.

That sorta makes sense Ultra. How would the rear amp would get signal for the turn on? Would I need to run a lead back there for the remote turn on from the head unit, or does it just start when it senses signal from the RCAs? Is that amp-dependent?

I'm looking at this Power Acoustik RZ4-2000D to put in the tour pak- it's the same width and a fraction lower (height) than the Soundstream PN4.520, but it IS 2 1/10" longer (11 1/10" vs. 9"). That shouldn't be an issue in the TP; my question is has anyone ever heard of this company? AND, since it's pushing more power (it also has 2 30-amp fuses- does that need a 60amp inline fuse??), is there some risk of "mismatch" (for lack of a better term)?

Also, where would be a good ground for the back of the bike? I'd like to be able to ground it relatively close to the Tour Pak. In addition, Sonicelectronix says that amp requires 4gauge wiring for the install, so that's a pretty stout wire that needs to be connected somewhere, and under the battery tray is kinda full right now!

I remember Power Acoustik from a long time ago. Quality and features were up there with the likes of Craig and Jensen. Is the amp worth it? Don't know. Nobody has posted a review or installed one AFAIK.

Somebody has to go first. Are you replacing the 4.520 with this or adding to it?

And, if it requires 4ga and things are getting crowded, you will probably have to run a distribution block. If your bike doesn't have the security siren, you can put it next to the fuse block. And there are plenty of rounding points at the back of the bike. IMO, I would run a ground to where the starter is grounded.

Mike - The more I look at that Power Acoustik amp the more I'm liking the specs. Please keep us posted on the performance. You will be the first person I know of to install one. Thanks!

Yay! I'm a Guinea pig!!

Might actually give this a go, though it will be a few weeks before I play around with it. SO if I'm not the first, I'll certainly be close behind it. Need to plan this out better in my own head (and budget!!).

There is a big metal plate in the tour pack, that the Moco uses for ground. I grounded both of my amps there........nice & short !

you'll need a remote turn on wire. you can run one from the head unit (which is what I'd do) or you can grab an accessory wire from under the seat.

been around for a long time so they must be doing something right.

I wouldn't use a 60A personally because these class D amps in our configurations will never see 30A draw. I'd use something like a 40A in a distribution block going to the battery and then a 30A for each wire going to the amps.

As GP pointed out, that steel plate in the tourpak is an excellent grounding point. short and sweet ground cables.

IMO, 8GA stranded wire (not that BS Oxygen Free crap) will be more than sufficient to run these amps.
