oui monsieur vous avez raison. N'est pas fort bon marché
yes sir you are right. Loud ain't cheap
Je ne peux pas ętre dans le Canada mais je suis Cajun. : -)

the higher the output voltage on the RCAs coming out the head unit, the lower you can keep your gains on your amp therefore reducing the chance of entering that area of the amp where distortion starts kicking in.
Now with that said, you can also go TOO HIGH so 4v is PLENTY high enough. I know a couple of guys on here bought and installed line drivers (basically an amplifier of the output signal of the head unit before it gets to the amp driving the speakers) but you've got to be real careful with those things as you'll easily destroy not only your speakers but your amp as well.

Any reason you aren't recommending the MM651's?
I ask, because I'm also in the planning stages of the upgrade from a Hogtunes setup for my Street Glide.
Would I be better served with the BT7P1's in the fairing mated to a RF PBR300x2 or the new SS PN2.350D, and some MM691's in saddle lids mated to another RF PBR300x2 or the new SS PN2.350D? Or simply a SS PN4.520D driving all 4 speakers...?

couple of reasons...
1.) little larger cone surface so a little bit more bottom end sound
2.) with this engine and exhaust setup and as loud as that's going to be, he's sure to blow them and BT is excellent about replacing their failed products.
you're always best to match components so I'd stick with the 651s in the fairing, the 691s in the saddlebags, and the 4.520D. Don't really see a need to install 2 seperate amps here. If you're worried about FM reception then check out Gone Riding's post about the ferrite core.

I brought my posts from the other thread back into mine so as not to hijack the other thread... Sorry about that...
I like the idea of more bottom-end sound. I am seriously lacking in that department right now with my Hogtunes setup.
The only reason I brought up the idea of using 2 amps is because I want to optimize their use as much as possible.
If I were to stick with the 4.520D, and decided to run the BT7P1's in the front, is there any issue with running 4ohm speakers in the front channel, and the 2.7 ohm Polk's in the bags off the rear channel of the amp? Per the amp specs, I should yield 100w @ 4ohm, and 130w @ 2ohm. Which sounds perfect for each speaker's specs.
Is my logic correct? Or is it not advisable to mix speakers of different impedance on the same amp?

I know you can mix impedance - we do it all the time when we run the front in parallel (4 speakers), and rear just to two speakers. Giving 2 ohm w/ 2 4 ohm up front and 2 or 4 ohm rear depending on which speakers.
I think he's talking more about complimentary speakers w/ sticking to one or the other. BUT look at GP and others who mix... It's not taboo and depends what you are trying to do.
I'd adjust your fade F-R to balance the speakers how you like and accommodate the 100 vs 130w RMS imbalance. w/ the MM651's in the rear getting more power, i'd fade to the front a bit because i like my music to come from the front.
I have a set of the BT7P1 Titan II's in my bike, and the MM651's in my brother's bike. I like them both - amazing upgrades from stock (both amped). My bike is in pieces (literally - being painted), so have limited time listening to the 7.1's so far. Brother's bike got done last weekend so I've listened to his more than mine so far!
The 7.1's are spendy. No arguing that. But sound amazing. Haven't added Polyfill yet, but will soon. They already have more low end than the MM's - but not huge amounts more. at 2x the cost, they are really NOT 2x the speaker! Not knocking them, but diminishing returns on the $. And i'd do it again btw!
Not totally apples to apples w/ two diff amps. Mine BT4180, his Massive BX2. Both around 180w RMS ea channel. (ish).
His are breaking in nicely and a bit more gains tweaking coming up. I'm also adding in the Ferrite cores Gone Riding showed us to help with EMI FM interference on his. Not sure how bad, but one station he listens to regularly (small local station) was lost. Going to test and see how bad before/after ferrites.
HTH - GL!

Thanks Sl33py,
I've got a couple of configurations going around in my head right now. The only common denominators right now are the SS 4.520D amp and the Sony DSX-s310btx Head unit.
I'm trying to get some more bass out of my next system. It is almost non-existent in my current Hogtunes setup.
That being said my first choice was to go with Polk MM651's in the front and retaining the Hogtunes Tweeter bar, with Polk MM691's eventually in some Hogtunes lids.
But now I'm starting to play with the idea of going with the BT7P1's in the front with the Hogtunes Tweeter bar, and the Pioneer TS-D6902R in the Hogtunes lids...
My music interests vary and are all over the place. Hard rock, metal, with the occasional rap and some folk/indie music thrown in for good measure. lol

RL - similar taste in music here. You might not appreciate the hogtunes tweeter bar after going either route (MM651's or BT 7.1's). Supposedly not that great, but you can swap in a decent tweeter. Spendy enclosure at that point.
But hey if you have it - give it a shot! I'd try it with the tweets enabled on your speakers, vs hogtunes tweets, and vice versa. You will find which you prefer and go that route!
I think the 7.1's and Pioneer 6902's is UN's setup - that should be a good thing!
GL!
