Hello,


I got two polk SR124-DVC subs, the Mb Quart DSC 1500.D amp to power them, and the Pioneer PRS800 head unit to augment SQ. And now, I'm trying to find the mid and high speakers to try to achieve the best possible SQ system together with those subs.


I've narrowed my search to the following 2 amp setups, depending on the highs and mids chosen:


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.


I will really appreciate your recommendations. Thanks.

Wow! What have you done to improve the cars acoustics? Unless you already installed a lot of damping inside the car that kind of power will surely find every resonance or rattle ruining the sound.

The best thing you can do is go out and listen to the speakers. Choose the one's that sound best to you. And if you are looking for the best sound on your budget, then forget about the rear speakers and put that money into your front speakers.

I would love to listen to those speakers, but unfortunately, there are no SQ competitions nor exhibitions in this country (Venezuela) whatsoever. This is why it's hard for me to choose between those, and need the experience from you guys to help me choose the best SQ components from within that list.


You also mentioned that I should forget the rear side and invest all speakers to the front stage. Is it possible to install 2 sets of comps in the front of a 2007 Jeep Liberty? Wouldn't that be cumbersome or saturated?


And mntmst, I will take into account the damping factor in due time.

We can tell you what we like. However it will be a big gamble on your part as it is likely that your tastes will be different. I personally wouldn't choose any of your choices. I have yet to hear a Focal or Polk speaker that sounded good. My personal favorites are the Diamond Audio Hex Pro components.

What I mean is use the money you would have spent on the rear speakers to purchase a better set of front speakers.

He's actually talking about sound damping material. "Damping factor" is a useless amplifier rating.

Well, I should wait and see if someone with experience with them steps in, since I'm strictly limited to those choices. Please don't ask why, just know that here in Venezuela the situation is bad for importing.

I agree, but if I buy a single great more expensive comp, I think that the 2 subs (1400 rms total) will overpower that single comp. So in that sense this system would be more SQL than SQ.

Yes, I know he was talking about sound damping material; I expressed myself incorrectly when I said "damping factor".

Depends on what type of sound you are after. Without auditioning them you can get the sound you are after with reviews. Focals tend to be on the bright side, something like dynaudio, and morel, tend to be more laid back. I would pick focal over polk though anyday.

Since I can't be able to listen myself to the different type of sounds, what exactly do you mean by being bright vs laid back?


And, is polk's MMC6500 an example of bright or laid back? And what about the SR6500?

Pretty much all of them including 3-way sets. They lack any kind of midbass response, are all super bright, and all have very poor imaging. And that was true even in a sound room.

And would you think the same about polk's MMC6500, or even the better SR6500?

bright=fatigueing sound that you won't want listen to very long.

laid back=sound you can listen for a long time.

Probably on the bright side looking at a few reviews. I would go with the focals, they win world championships in car audio, and polk never wins anything.

According to Steven Kephart, the focals are very bright, too. But if they've won championships, there should be something else which gives them an edge over the polks. The focals I've got available here are the 165vr3, and the 165 A1. From polks I got available the MMC6500 and the SR6500. Since I felt more identified with a more laid back sound than a bright sound, between the 4, which would be more laid back and with greater SQ?


Also, consider that the polks have more rms power, which I think can help them keep pace with the 2 SR124-DVC subs I got..


What do you think guys?

Actually bright refers to a speaker with peaks in the higher frequencies. Focal, MB Quart, Boston, and some other companies are known to be this way. Some people like it while others, like me, prefer a more natural sounding top end.


Listening fatigue is generally caused by high levels of 3rd order or greater harmonic distortion.

Luckily that's why they have Eq. You can achieve a flat response with any of those speakers.

Hard to say without hearing them. Some reviews claim the polks are bright also. Might have to up your budget if you want a silk dome tweeter which usually has warmer sound characteristics. And like i said above, there is always eq

Thanks guys. I can't increase my available budget. I will have to choose the best from those options.


I'm unfortunately really not sure whether if I will prefer a brighter or warmer sound. The best comps I got available are Focal's 165vr3 and Polk's SR6500 and MMC6500. I can get the first two for the same price, and the last one on half the price, and only one of them is feasible for me to purchase.


Since this may be subjective, I leave you to your experience to decide which of them can generally achieve the best sounding experience in music like rock, reggae, and techno.


So, which of those would have the best general SQ, and also have more power to keep up with the two subs' 1400 rms of power?

Ok, I've decided I would definitely go with only the SR6500 comp front stage. Now, I'm trying to see which is the best amp setup for powering them. A polk specialist informed that the mids from that comp can handle 150 rms, while the tweeters 80 rms. I would like to power the comp to their max potential. So I'm trying to find an amp setup that would do this. Also, please remember that SQ is the main focus, so the amp setup must be SQ oriented. Since I don't have much availability here, these are the choices I have:


- 1 Focal Solid 4 to power the tweeters, leaving 2 channels free. 1 Kenwood KAC-7203 to power the mids.


- 1 Mb Quart Dsc-2150 to power the mids, 1 Mb Quart Dsc-280 to power the tweeters. According to the official manual, this amps only manage a frequency range of 10hz-1.2khz, which I'm not sure whether if this would sound horrible with mids and tweeters, considering they are in higher frequencies. Please help me clear this.


- 1 JBL GTO1004 bi amped to the SR6500


- 1 Focal Solid 4 bi amped to the SR6500


-1 Kicker Zx 850.4


Which one do you think would be better?
