OK I know it's been beaten to death elsewhere I'm sure, but.... Just installed the PBR 300x2 and infinity Kappa 62.11i's in the front fairing of the 13 RGU and am looking to add another amp and speakers in the tp pods. For those who have used multiple 6.5's which 2 ohm speaker has given you the best performance? Also, Can you recommend a 6.5 speaker for the rear tour pack pod? All suggestions considered. Thanks for the info, especially looking to hear from dbell and h-donut.

Am only interested in the 2 ohm sets as I still plan on using the oem hk hu

For 2 ohm, unless you have wads of money you want to spend, the Infinity is the best bang for buck that I know of. Also with the size of the pods, test the fit first.

Are you planning to amp the rear speaker pods? If so, you're not constrained by the 2 ohm only speakers.

Not real sure how you arrived at this conclusion since the head unit (factory HK) is 2 ohms and the amp (PBR300x2) is 2 ohms and I'm planning on using the onboard wiring harness for the ultra which should power the speakers in parallel so 2 ohm speakers should be required if I've done my research correctly. Any thoughts about this from the experts? H-donut? Dbell? Anybody?!?

I think what 09Sharknose is saying is that your not confined because you can use a different amp. You're not confined anyway because if you used 4 ohm speakers you wouldn't hurt the amp or the HU, just you wouldn't get the most power out of it.

Thanks for the explanation Dbell. I'm really not interested on spending money on an inefficient system, or to put it another way, I want to get the most performance possible for the least amount of money. That would seem to be using compatible 2 ohm components throughout in order to maximize the performance and output of the components. Also, I thought I had read on here that using a 4 ohm speakers with a 2 ohm hu and amp would increase the heat in the hu and amp and therefore shorten the life of both. Bottom line I guess is who makes the best 2ohm speakers, that can handle the output from a 300 watt, 2 channel, 2 ohm amp? I willing to drop a couple of bills for the right speakers but want to get teh best bang for the buck.

What I meant is exactly what I said. The HU never "sees" the speaker ohm load once you place an amp inline between the HU and the speakers.

The PBR is NOT a 2ohm amp, it is an amp that is 2ohm stable. As are the HW amps among others. The word difference is meaningful.

So what I was saying is that if you're planning to amp the rear channels like you did the front, you're not limited to 2ohm speakers based on either the HU or the RF amp. And personally I don't know of ONE amp that is 2 ohm exclusively. There may be some out there. You will find 4 ohm amps that aren't 2 ohm stable, but rare is the 2 ohm amp that can't operate at 4. .

I know what you're saying, but a 2ohm stable amp is at max efficiency with 2ohm speakers, you can use 4 ohm speakers and of course they won't hurt the amp, but you also won't draw maximum power, if that's what you want. On the other hand, 2ohm speakers can ruin a 4 ohm amp. The OP seems to want to match his amp and speakers with the same impedance which will give him max efficiency.

I have the Mid-level Focal speakers and a fosgate amp...they werent all that pricey and they have blown anyone i know's system out of the water even with a stock deck. I only have the faring speakers in 6.5" and they are just as loud if not louder and way clearer than some 4 speaker systems I have seen...

I put mine under the HU. Got a bracket to do it off eBay.

True. My point was that he seemed to think that since the HU is 2ohm, he had to use a 2 ohm amp as well.

He probably also doesn't know that with a 2 ohm stable amp, he can run 4, 4 ohm speakers at 75w each and still have the most efficient load on his amp and utilize all of the power the amp is producing.

And that might be a a little more efficient than running 150w through a speaker only rated for half that.

Okay amongst the debate between 2ohm and 4ohm , and people chiming in about what they thought were the best, front fairing speakers, what was a good conclusion for TP speakers. I already have RF300 and J&M for the front , I would like a good combo for the TP speakers.
