SQ Setup for Mids and Highs

[Bandieramonte 10+ year member]

Those subs would not fit in my vehicle, and, remember, I'm not aiming for SPL. As you said, they aren't for my application.

Well the thing is, you can always turn the bass down. But the way I see it is, if you turn the bass down to a level that one single sub would provide...then you've wasted the money and trunk space installing both. That's why I recommend just trying one out first. For 2 12s off that amount of power, as long as you give your components enough power, there is no need to do 2 sets of components in front. It will just be a headache installing 2 sets of mid and 2 sets of tweeters. Aiming, tuning, time alignment will all be a lot more work, not to mention finding/making room for 2 6.5s a side. My philosophy is start out with the least amount of work/components possible. Go from there. You may be satisfied with one sub and one set of components.

I understand, so, you mean that even two SR comps at their full potential wont do well with both SR subs? I see that the alignment and tuning would be harder, but I'm thinking that the Pioneer PRS800 head unit would solve that. And if it's hard to install two comps in the front door, is it a terrible idea to install the second comp set in the trunk, or in the back doors?

Up to you man. Your sq seems more like you want it loud and clear. In that case go for it. Both subs and comps in the rear. That would give you that dance club "surround sound" loudness. I strive for accurate reproduction, imaging and sound stage though, as if I'm at a concert in my drivers seat. That doesn't seem like what you're looking for, and that's fine but not my taste. If youre looking for a really loud system and want it to have clear detailed frequecy response, but don't care about imaging and sound stage, then yes your way should be fine for you. Before you buy anything else though, I'd meet up with some of the SQ guys in your area and take a listen to some other systems...

In the country I live in (Venezuela), all the car audio enthusiasts are busy concerned with pure SPL systems, and all the car shows and competitions are SPL oriented, that's why this process has been so hard for me.. got no SQ or SQL cars to listen myself //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I really appreciate your help in trying to define the closest SQ system possible for me and those subs. I thought that with those subs, I could install a comp in the front door to achieve good imaging and concert-like audio, while at the same time installing a second comp in the rear so as to balance the power from the subs, without sacrificing much SQ. But it seems this is hard.

So, what is more acceptable for better sound: one comp in the front and one in the rear, or both set of comps in the rear? (or is there anything else I can do to try and achieve a closer concert-like sound with those subs?)

I vote for pro audio mids (B&C, 18Sound), they can handle loads of power, are efficient as hell, and you'll have a better chance of them not sounding like *** at high volumes.

Ok, I narrowed my amp search on one of the following amp setups, depending on the final mids and highs setup I decide to pursue:

1 amp JBL GTO1004 or

2 amps Focal Solid 4

Regarding the mids and highs speakers, I narrowed my search to the following final choices (all these are adjusted to my maximum available budget):

1 set polk SR6500 front stage

1 set Focal 165A1 for the trunk

1 set polk SR6500 front stage

1 pair Alpine SPS-600 for the trunk

1 set polk MMC6500 front stage

2 sets Focal 165A1 for the trunk

1 set polk MMC6500 front stage

2 pairs Alpine SPS-600 for the trunk

1 set polk MMC6500 front stage

1 set polk MMC6500 for the trunk

1 set polk MMC6500 front stage

1 pair mids powerbass 4XL-65-92 in the trunk

1 pair super tweeters powerbass S-1s in the trunk

1 set polk MMC6500 front stage

1 pair mids Eminence Beta-6a in the trunk

1 pair super tweeters Super Tweeter Jbl P26t in the trunk

1 set of focal 165 A1 front stage

1 set of focal 165 A1 rear doors

2 sets of focal 165 A1 for the trunk

Well, those are my possible choices available in the local market, and one of both amp setups should be chosen depending on the choice for mids and highs speakers.

Please remember that, while it seems that I can't pursue a pure SQ system having two subs at 1400 rms total, my main goal is to achieve the best possible sounding system with the two polk SR124-DVC subs and the PRS800 pioneer head unit(want more SQ than SPL), without any frequency range overpowering the other. Also, remember this is for a 2007 Jeep Liberty.

Why Polk???? mmc line???, I've heard them they are ok for the price.

why rear fill???? & you are trying for SQ! interesting.

The Focal amps are really nice,& the Polk SR subs sound really nice as well.

but have you looked into IDMAX for subs??? or the ID comps for your front speakers???

What about deadener??? it's just as important as the speakers!

placement & aiming your tweeters & mids will have a great effect on you front stage as well.

Dude read the thread.

But he does have a point. Have you factored in deadening and wiring? That being said, the Focal Access comps are for very budgeted installs. They're pretty crappy IMO. Honestly just go for a set of SR6500 in front, and some of the Momo coaxs in the rear. Pick up a matching MB Quart 4ch and you'll be good. The Momo line used to be pretty decent, but idk about the current stuff. You won't be using your head unit to it's full potential not running active, but this will be a great set up to get you going for a while.

 

[LaserRed38 10+ year member]

Btw, how are you installing your subs? I hope you're making a custom enclosure for them. It would be a shame to run them in a prefab box.

Also, down the road. If you ever want to mess with active, your Pioneer has built in crossovers and slopes. You can mix and match different mids/tweeters or run your current comps active to start and maybe at another mid. Just food for thought for you to consider down the road.

Of you opt for SR6500s, make sure you're comfortable tuning them. I posted a review of the speakers with some discussion about tuning. You should be able to find it with a quick search.

Treating your vehicle to be as acoustically friendly as possible is probably the best thing you can for this monster many call SQ.

I did the search, found the thread you started titled "Polk SR6500 review", followed the link you mentioned in your opening post:

and it appears to be broken.. I would really like to see your review, can you send me the good link?

I just read first page of squeak9798's Proper Door Sound Deadening and You thread, and the more I read about this SQ business, the more I realize I got much to learn... This is not going to be easy for me considering the country I live in is dead to SQ: there is no availability of appropriate deadening materials nor specialized installers that do so. This would be more of a longer term process for me. I should try this first install, and later try an augmented install considering this process.

When you say Momo Coaxs, are you referring to the MMC6500 comps? The MB Quart 4ch amp is nice, but unfortunately I got no availability here in the local store (Venezuela has narrow availability due to importing barriers). The good amps available are both of those I mentioned before; the rest are lanzar, power acoustic, and similar brands... crappy imo

Btw, how are you installing your subs? I hope you're making a custom enclosure for them. It would be a shame to run them in a prefab box.

Of course I'm making a custom enclosure, exactly complying with the SR's white paper, taking in account woofer displacemtent, Qtc factors, etc. I never have messed with active or passive, but I will be trying the different functionalities of crossover, time alignment, auto eq, xover, etc etc when I install the sound in my car, but the last things missing are the highs and mids (which I just learned that I did this backwards).

So, you think that, from the choices list I just posted, the SR6500 front stage together with the momo coaxs (still waiting to see if you meant MMC6500) in the rear, would be the best sounding one from within those? And also, if I power them to the max rms, could it keep pace with the 2 subs?
