Help sorting out my dilemma
dont have deep audio pockets but in hindsight prolly would have been better off with more quality gear for what I ended up spending over last couple years.
presently have ss pn1000,infinity kappa 6.5, Polk 652 and mmats 601.8.
have a jvc after market h/u I can adjust.
in hindsight would have gone with a sd amp and hertz 165 speakers up front and ? In the lowers.
may still up grade to the hertz or dB wdx in the fairing and then unsure about lowers.
i have presently 3 pairs of 6.5 speakers but only plan on fronts and lowers. No bags.
what might I do with this? Only looking for good highway sound. If I can attain that then the rest is gravy.

Weeboy it sounds like you might have a similar setup to what I had when I first started out. If I understand right you have fairing, lowers, and rear pods. Is that correct? If so I am curious as to how the 8 ohm Mmats fit into the equation with that amp. How do you have all of that wired to the amp? I ask because I am wondering if you may get more sound just by swapping out the Mmats to a four ohm pair which is what I ran on that same amp and was pleased with.
I had three sets of speakers on that amp at first and it was OK, but I wasn't truly happy with the sound until I gave each set of speakers it's own amp channel so to speak. That way I could adjust each set so that they blended well. At first running four speakers on one set of amp outputs sounded like a good idea, but they just didn't blend well. I had the lowers and rear pods on the same amp channel and when I brought up the lowers to where they blended well with the fairing speakers I couldn't hear the rear pods. If I faded back to where I could hear the rear pods the lowers drowned out the fairing speakers. On the same token I have talked to some folks that had the fairing speakers and lowers on the same channel and they said they couldn't hear the lowers much at all.
It may be that if you just swap out the Mmats to a four ohm pair and get a small micro amp for the rear pods you would be able to better utilize those six speakers.
I apologize if I have misunderstood your build.

Yeah, never been more than 4. Two front, two lower.

This, the 601.8s will scream off that amp ran parallel on 3 and 4. They will be by far louder than either coax you have in the dash and youll have no issue hearing them going down the highway. Someone makes a frequency capper that Im sure someone else can tell you the name of (I dont remember it), but the mmats dont sound that great when allowed to naturally roll off up top. I cap mine at 5k hz on the top end and 110 on the bottom and they are loud as hell and very clear for a cheap speaker.

If you want a cheap way to cap the upper end you could use a set of FMODs from Harrison Labs:
Harrison Laboratory
A set of low pass 6500 Hz might work for those speakers:

Not sure I follow the capping idea. Never heard that before. What exactly am I looking for?
is it not the same as setting the high and low crossover in the head unit.
thanks btw for all the replies.

If your head unit can set low pass and high pass cutoff points on the same channel then you are good to go. I don't have any experience with modern head units so I don't always think along those lines.
According to Mmats the frequency range of those speakers is about 120 Hz to 5000 Hz. If you pass frequencies much above 5000 Hz to those speakers they will not be as efficient as they could be. Also when you do that they tend to narrow their audio cone so to speak. I have heard it referred to as "beaming". I played mine with the full upper range for a while and they sounded OK but when I capped off the frequencies above 5000 Hz they definitely sounded better. They were louder and cleaner sounding.
