Hogtune issues, I need new speakers!!! Help please

So, I'm having issues, I'm totally frustrated with the sound presently, and I'm not sure I quite understand the 2 vs. 4 ohm thing as well.

I've actually done a search in this forum to try and find some recommendations, and since I'm not that swift with the 2vs4 ohm thing, I'm getting confused.

Let me explain.

I have a 16 FLTRX. I had an FLHX before with hogtunes in it and was very happy with the sound. So I went HT again, and got the amp and speaker kit to fit my 16 RG and though that the amp and 2 speakers would be enough. Amp is 100W per channel (so they say) speakers are rate 125w RMS all at 2 OHMS. Well after replacing the speakers twice with Hogtunes they are all doing the same thing, at about 77-80% full sound they crackle (Hogtunes was really good and replaced them no problem while under warranty, but they all did the same thing). Now the warranty is done, and I'm still frustrated and the sound is shit.

I listen loud since I'm old, and a 1/2 deaf drummer, not to mention that I only have a 9" klockwerks windscreen on there. I actually went as far as lined the inside of the fairing to help with acoustics as well.

So I'm looking for new speakers. I would dump the whole HT setup but budget won't allow it right now. So a speaker upgrade looks like its the only thing I can afford.

I'm assuming from my very limited knowledge, I need at least 100W speakers at 2 ohms, so I'm looking at the Infinity-Kappa-62-11i, they are 2ohms, rated for 125W RMS. They seem to be one of the higher rated speakers on this site.

with the amp at 100W per channel, should I be looking for higher rated wattage speakers?

Can I go 4 ohm speakers? If I do, do I loose anything?

Thanks in advance for your help!

The Kappas are a good speaker. But to me, they are like a gateway drug. They don't sound bad at first, but then you realize you wold like just a bit more. I'm a huge fan of the Arc 602's. Not cheap, but they are the first speakers I've ever had I didn't want to upgrade. I push mine with a CV B52 amp.

As a general rule you can use 4 ohm speakers with a 2 ohm amp. (major exception would be Tube amplifier's which wont be a concern for a motorcycle.) Keep in mind power ratings when doing so. Think of it like this.

Lets say you have a Amp that outputs 100 watts RMS at 4 ohm. Now you hook that up to a 2 ohm speaker.
1st the speaker will generally see nearly double the wattage at 2 ohm. So in a sense, you a sending 200 watts RMS.
2nd You must be careful when doing so as this can damage the amplifier, when doing this make sure the amp is 2 ohm stable.

So, lets say you have a Amp that outputs 100 watts RMS at 2ohm. Now hook up to a 4 ohm speaker
you are gonna half the power going to that speaker. So that speaker would see 50 watts RMS at 4ohm.
Modern Solid State amplifiers will not be harmed by doing this, but the speaker will also not be as loud
as it could potentially be. A quality amp will have a 4 ohm and 2ohm rating if it is 2ohm stable. If you are not sure, and see no listing in the spec's contact the manufacturer. It will save you from burning up your amp down the road.

I would suggest that when looking for speaker and amp combinations you do your best to match the ohm rating, or at least make sure the amp you are using is 2 ohm stable. As far as power is concerned Peak Power rating numbers are for show, and bragging rights. The RMS number is the number to look out for.

A small cheat is to find the fuse on the amp, and see what its rating at. If its a 20 amp fuse and they are advertising some huge power numbers you can bet its a lie. multiply the fuse rating number by the voltage. So lets say 20amp*13.5volt = 270 watts.That is a max system number so lets say 135 watts per channel on a 2 channel amp. The RMS would be even lower still. 65 or 75 watts per channel. That would be a peak number. If the amp in question is advertising 400 watts, you know they are full of it. In general the Max power number is definitely over inflated. Some amp manufactures over inflate the RMS numbers as well, but it does give you a good ballpark number to work with.
Keep in mind most people damage speakers from over driving them with too little power causing speakers to clip at high volume. I Hope this helps you a little and does not confuse you even more.

Are you sure the amp isn't problem?
if you got the other forum in the audio section they have threads on everything you can imagine audio wise by some very knowledgable people.

My suggestion would be to sell that amp and get something different.

I have Arcs in my bike now. They are OK, power hungry for sure. They will be coming out soon.

If you just want to keep that amp, on a budget, Kappa is the choice.

I have a set in the garage in the factory box. Used for a few months. If your interested let me know

2009 Road Glide. 16 in Vindikta Wild Cats. Aquatic AV, Stinger 700X4 to MMats PA 601, Audiopipe horns.
Ground Zero 7X10 in the lids w/ sspn.4 1000d, tuned with DD Audio DSI-2. S&S 106, lifters, push rods and AC. Drago 2. CycleRama 575. Progressive monotones -1in. 12in. HD adjustable rear shocks. Painted inner fairing. Tuned with TTS. Blacked out!
