I recently put the Hogtunes Big Ultra kit (4 speakers and 40.4 amp) on my 2010 FLHX. I am not happy with the sound. The louder it gets the more distorted the sound gets. So I was looking at purchasing the J&M 7.25 speakers and running them off the hogtunes 40.4 amp that I currently have. Wanted to know if the sound would be worth spending the money or if anyone is happy with the sound of the 7.25 speakers.

 

I'm interested too, subscribing.

 

I put the Roker speakers on my Road Glide Ultra and it has the 40w per channel amp. Pretty happy with the sound quality coming out of them

 

I have the regular 7.25 J&Ms with 125 watts per speaker, and I'm pretty satisfied with the sound.
I wasn't that impressed with the speakers, until I added the amp.

 

I had the same issue. I purchased a Line Out Converter and it really helped. I think it restricts your amp from boosting a distorted signal.

I bought mine from Amazon for about $12 -PAC SNI-35 Adjustable 2-Channel Line Out Converter -

Good Luck.

 

A friend of mine did the same thing. He added the speakers first and then later added the amp. It sounded cleaner before installing the amp but at highway speed it distorts with or without the amp but was still cleaner/clearer before the amp install. Im running the Hawg Wired double shot system in my Road Glide Custom. Very loud, very clear but not much bass but how much bass can you really get out of a 6.5" speaker...

 

Usually distortion is caused from the deck. Deck distortion happens when it cant produce enough power to go as loud as you are asking. An amp normally takes care of that problem. If it doesn't, your deck might be over driving your amp. If you get the right combination you can crank it till your ears bleed!

when looking at speakers, the spec is "sensitivity"

X dB at 1 watt at 1 meter

meaning that a 1 watt signal into the speaker, measured at 1 meter = X dB

87 dB is not so good, 92 dB is average

98 dB would be more than 10 times the volume of the 87 dB speaker at the exact same "volume setting" on the head unit

so look at speakers which have good specs for sensitivity.

"watt" rating for speaker only mean how much electricity they can handle from the amp with out blowing--- but nothing to do with sound provided from that electricity

watt ratings for amps are a good indicator, but in conjunction with Total Harmonic Distortion (THD). The sansui and marantz receivers we had in the 70's typically were good for less than 1% THD--- I have seen amps which have specs at high at 10% THD at full power--- they were really only capable of clean clear power at perhaps 50% of their "rated output" in watts.

Careful reading of manufacturers specs and understanding of terms will lead to better results
