Putting an amp on the H-D Boom Upgrade Speakers
On my 2014 Limited I have upgraded both front and rears to the Boom speakers (no amp). I know not everyone digs these speakers but I got a decent deal on them and can definitely tell a difference from stock so for now I'd like to keep them. My understanding is that these are 75w speakers.
I'm looking for some advice on an amp to power them to their full potential. I'd like to have a single amp that could power all 4 speakers (I've read much talk on having two amps but not sure I need or want that.)
There is the HD amp as an option and I know of many other names out there but I get lost on the proper model numbers and ratings that fit the bill. Help!
Assuming I'm not going to change out the speakers and would like to install a single amp for the entire bike, can I get some suggestions?
I apologize if this should be in the 2014 sound upgrade thread but that thing is unwieldy as all get out for asking a specific question!
Thanks to all!

I think any amp you pair with these will have a good chance at blowing the speaker. 75W is just not very powerful. I'm no expert but I think you always want to run your speakers no higher than the max RMS output of the amp or BOOM! You blow your speakers. For 4 speakers you will want a 4 channel amp. A class D amp and you run the risk of blocking your FM signal so no radio reception.
Good Luck.

I'm sure there will be a few on here that will tell you "get your money back", but as long as you are happy.

Yes - that is the part number. Funny I just posted about the 2ohm vs. 4ohm and I was going to guess 2ohm from a few things I found but couldn't find anything definitive.

Are you sure the boom speakers are rated at 75 watts RMS? No one has been able to verify that number. Anyway if you don't care about radio reception the only amp I can think of to put on the booms is the Sound stream Picasso Nano PN4.320D. 80 x 4 @ 2 Ohms.

Maybe I'm not stating the right numbers. I was going by the HD website for the speakers that says they have 75w of power per speaker. And the amp page says it is 300w delivering 75w per channel.

As always Harley Davidson is a little misleading with their specs. If you notice on the speaker page they say "75 watts of power in each speaker" which means absolutely nothing. Are they talking RMS or Peak Power? However, I do see where they claim their amp is producing 75 watts to each speaker @ 2 ohms. I'm not sure what kind of deal you got but they list for $199.00 bucks. No way I would pay 200.00 bucks for that speaker.

You mention a two speaker setup. On a 4 speaker bike is the thought you only really need to make the fronts top-notch as the rears don't play as big of a role in what you hear at speed?
If you go with a 2 channel amp that only drives the fronts I'm assuming you need the flash from HD to disable the internal amp so it works properly? If that's the case what drives the rears from that point on? Is it just the stock head unit? If so, with the internal amp disabled it would seem they'd be really quiet? I'm a little confused on how that all works.
Thanks for the thoughts and comments.
