Here's what I am working with currently...

 

Looks like mine about a month ago.

Hope it works out. I know you would have been happy with the 4180. Incredible power and a lifetime warranty, all from a product made in the U.S..

 

DAMN! I wish I had known about that before I started with all of this. That 4180 is a beast. But oh well. So, as of right now, I have taken you guys advice and added a second amp to run the front Infinitys. I picked up a PBR300x2 from one of my buddies in the bike club and I installed it last night. Started on it at about 9 and didnt finish until about 6:30 this morning. Why so long??? Well, I basically had to replace all of the wiring for the speakers and amps from front to back.

The JL amp and the PBR both recommend using 16 gauge speaker wire. Well, the wiring that I had on the bike previously (J&M Rokker) was like 20 or 22 gauge. It may have been 18. All I know is that it wasnt 16 gauge like what is recommended. So, I had to rip out all of the old J&M wiring and re-run all new 16 gauge high quality speaker wire.

Then, the next challenge was running the power wires to both amps. Again, the J&M setup was not sufficient enough to power either of the amps, based on the manufacturer recommendations. For the life of me, I cannot understand how a Rokker amp that is set up to run more RMS power at 2 ohms than the other two can get by with such small wire for power and ground. Also, I forgot when I did the initial install 15k miles ago, the ground for the J&M rokker amp is hooked into the battery. This also is a no-go because it is longer than the recommended max of 18" for a ground wire. So, I had to pull all of the rokker power wires out and re-installed new proper 8 gauge power and ground wires.

Now, I finally have both amps hooked up and running. I ended up trying like 5 times to get that damn XD400/4 to fit in the fairing. After annoying the hell out of myself, I finally decided to go into the phone and search "XD400/4 in Road Glide". Well, well, well...what do I find??? I discover that I was correct the entire time...I knew this amp would fit in that fairing, just didnt know how. Come to find out, it fits perfectly on top of the aftermarket radio. So I moved it to that location, did a test fit of the fairing and tada...it fits perfect.

Oh, I forgot this too....the rokker gauge tweeters that I have? They dont work anymore. I tried running them directly off the amp, in series off the Infinitys, and off the radio output speakers...and nothing! So as of right now, I am not so pleased with my J&M products. Not saying anything bad...awesome company, just not understanding some of the logic and why these tweeters (that are only like a month old) are not working. Now, I am kinda wishing I would've just either done this from the beginning, or tried out the biketronics stuff back when I bought the J&M stuff for the bike.

So, today...I will heading out to fry's and picking up a pair of polk tweeters. I guess they fit perfectly in the gauge housing and only need a small spacer to be secured in tightly. I will try to just send all of this Rokker stuff back to J&M and see what we can do. I know for sure that they are gonna refund my money for these tweeters. The amp and rokker 7.25s? I have no clue what the outcome will be. I will be taking more pics and posting them here to mark my progress as time moves forward.

One question though...I currently have the ground wire for the xd400/4 amp connected to a ground spot on the back of the aftermarket radio. Is this going to be ok?

 

Eshaw . . Just for clarification Sir. . . The X4 you mentioned in your original post was the PBR? Not the JL. Both are rated at 75 watts per channel but you can run your speakers in parallel with the JL. Not with the PBR X4. The PBR X4 is the amp I was referring to for lack of power to the Pioneers.


Well, im done playing around with amp and speaker combos. I have went thru multiple pairs of speakers and finally found the ones that I like and what do you know it...the damn rokker amp burns up! Bummer!!! So, I go to the soundstream and it kills my fm reception on my radio (which is aftermarket). Been searching around and wanted to do 2 pbr amps, one x2 for the 2 ohm infinity 62.11i, and one x4 to power the four pioneer 6x9s in the bag.

 

eshaw301 ,,,,,,

the power & ground wires for all J&M amps are 10ga ,,,,, more than heavy enough for the ROKKER XTP 500w RMS amp , and plenty also for 2 of the RF 300 amps, as the REAL RMS output of the Rockford Fosgate amps is significantly less than their rated 300w ,,,,,,

also sounds like you have a real wiring "conglomeration" going together ,,,,,,

Please let me know if I can be of any assistance in getting your J&M tweeters connected up and functioning again ,,,,,,

 

really? I'd like to know when RF started skimping on the output power of their amps. I haven't seen a PBR300x2 yet that had less than 180w per channel vs the advertised 150x2.

REALLY !?,,,,, I think you and I should take this private and discuss before it turns into a RF bashing thread ,,,,,

 

no need sir.. I have all the information I need including a personal friend who is a designing engineer for RF amps.

 

I have to agree with John on the power wire as I know the quality of his power and ground wires. A good quality 10ga power wire is more than sufficient for these amps, especially the Class D and PBR series.

That crap that audio stores sell you that is "oxygen free", 4ga in outer diameter and 16ga inner diameter is just that, crap and a sales gimmick. A solid stranded copper wire in 10ga size will carry up to 40a over a 100' length before voltage/current drop starts to occur.

 

I settled on the PBR 300x2 and the JL XD400/4. I have the PBR pushing the infinity kappas in the front and the XD400/4 pushing the pioneers in the rear. Overall, the bike sounds a whole lot louder and clearer than before. When using the Rokker 500 watt amp, however, the rokker did have the pioneers hitting harder with lots more bass. Dont know if it was because they were ran in parallel or what, but that's the biggest difference so far that I have noticed. And the infinity's are all that they are cracked up to be. Prior to using them, I would turn the volume on the stereo to about 28 before distortion. Now, I can go up to about 40 on the stereo volume before it just gets ear piercingly loud (still no distortion). Yes, the soundstream did kill my FM reception so it got took out of the bike. Now, the issue is the tweeters. Finally got them to work using the speaker wires (instead of running them in series with the infinitys, in which they didnt work), but now they sound terribly distorted when the stereo is turned up. Every other speaker on my bike can handle the power but the rokker tweeters cant. Dont know if its because they are getting their signal from the radio, but it is noticeable at right around volume level of 28 (which just so happens to be what the distortion point was when the rokkers were in). So, I put passive crossovers on them and got the same result. So, I ordered the Infinity Kappa 10.9T 1" tweeter to go in the gauges in place of the rokker tweeters. I heard the kappa tweeters in person and they were awesome. They should arrive tomorrow and I will come back with an update on them.
