edgesportguy Posted May 9, 2013 Report Share Posted May 9, 2013 I just installed some Polk 5x7 Dxi's in all 4 doors of my 2013 Edge Sport with the upgraded stock Sony system and really heard very little difference (if not worse) from the stock speakers. The factory speakers were pretty good quality and had vinyl cones with butyl rubber surrounds, and the rear speakers actually had heavier magnets than the Polks. I'm upgrading the sub next with a Alpine MRP-M500 amp and a JL Audio 8W1v2-4 8" sub in the stock box. I'll be reinforcing the stock sub box by bonding 1/2 MDF and dynamat to it to firm it up. I think this is where I'll really see some improvement and much deeper bass response. Will keep you posted Quote Link to comment Share on other sites More sharing options...
shoulinpanther Posted May 10, 2013 Report Share Posted May 10, 2013 So did you upgrade the tweeters and center and d-pillars yet? Also you say it might be worse did you accidentally reverse polarity? Also not knocking Polk but why not infinity kappas or Boston acoustics? Just curious because everyone else that I have heard from that has upgraded the interior speakers where happy and satisfied with the sound improvement.

ferneyhough Posted May 10, 2013 Report Share Posted May 10, 2013 The RMS on the stock speaker is 25 watts if Im not mistaking & Im going to guess that the Polk speakers are @ least 50 watt rms, sounds like you need a more powerfull amp to move the speakers. My speakers for example sound better since I installed an amp to the factory oem system. Hope this helps Quote Link to comment Share on other sites More sharing options...
edgesportguy Posted May 10, 2013 Author Report Share Posted May 10, 2013 Hmm - I've always liked Polk's. I did not upgrade the tweeters and center and d-pillars. What size is the center speaker? Maybe I'll try swapping out to the infinity kappas or Boston Acoustics if I can return the Polk's. I'm looking forward to getting the sub in as I think it's going to make a huge difference Thanks for the feedback Quote Link to comment Share on other sites More sharing options...
edgesportguy Posted May 10, 2013 Author Report Share Posted May 10, 2013 Which model of the Infinities or Boston Acoustics am I looking for? Quote Link to comment Share on other sites More sharing options...
Dingo Posted May 10, 2013 Report Share Posted May 10, 2013 I have SL80s in the doors. The center and d-pillars are all 3.5". Quote Link to comment Share on other sites More sharing options...

Dingo Posted May 10, 2013 Report Share Posted May 10, 2013 Look for sr80s. They're similar. Quote Link to comment Share on other sites More sharing options...
shoulinpanther Posted May 10, 2013 Report Share Posted May 10, 2013 Infinity kappas 6x8 same size as 5x7 just named that way if you go infinity Quote Link to comment Share on other sites More sharing options...
edgesportguy Posted May 10, 2013 Author Report Share Posted May 10, 2013 Returning the Polks and just ordered 2 pairs of INFINITY KAPPA 682.11CF http://www.crutchfield.com/p_10868211CF/Infinity-Kappa-682-11cf.html?tp=93&awkw=44731452865&awat=pla&awnw=g&awcr=16259734945&awdv=c Quote Link to comment Share on other sites More sharing options...
shoulinpanther Posted May 10, 2013 Report Share Posted May 10, 2013 Hopefully they will provide you with the sound you are looking for, these are the exact speakers I plan on using for doors. Quote Link to comment Share on other sites More sharing options...
fishx65 Posted May 10, 2013 Report Share Posted May 10, 2013 The Infinitys have a little better sensitivity, better frequency response and you can pivot the tweets for better imaging. They should sound better then the Polks. I do wonder how the factory amp will handle their 2 ohm impedance. Quote Link to comment Share on other sites More sharing options...
Anthony Derrick Anderson Posted May 11, 2013 Report Share Posted May 11, 2013 Have you guys looked at the JL Audio Stealth box ? http://www.jlaudio.com/car-audio-stealthbox-ford-edge Quote Link to comment Share on other sites More sharing options...
Rockballer Posted May 15, 2013 Report Share Posted May 15, 2013 You took out the Sony system for Polk audio.... LOL..... the Sony systems that come in our edges are extremely good systems. I Would not see any reason IMO to pull it out for something else. Unless your going into a stereo competition. Quote Link to comment Share on other sites More sharing options...

My Kappas should be here any day now and am looking forward to dropping 'em in as everyone seems to love them. As far as the 2 ohm, these should be fine according to other threads that specifically addressing this I am definitely disappointed in the factory system - the highs were pretty good, but I thought mids were muddy, and the factory sub absolutely horrible with it breaking up at just half volume. Not looking for big boom - just some nice tight full bass, with crisp, clearly defined mids and highs. I've personally had great experience with Polks, though I did go higher end with true components, driven by plenty, of power in my truck Quote Link to comment Share on other sites More sharing options...
wannabang Posted May 16, 2013 Report Share Posted May 16, 2013 I usually find that the upgraded sound packages offered nowadays are quite nice. On the other hand, I've only used RF, Sony, Incriminator, and Infinity aftermarkets and have been satisfied with all of them as an upgrade.

edgesportguy Posted May 18, 2013 Author Report Share Posted May 18, 2013 (edited) I got the Infinity Kappa's in - they do sound better than the stock Sony speakers, but personally I wouldn't spend the money to do it again. Modifying the stock box and putting in a JL Audio 8" sub powered by a MRP-M500 Alpine amp ended up pretty much being a flop. I bonded 1/2" MDF to every flat surface of the stock box, fiberglassed the entire thing with two layers of matt, and Dynamatted the whole inside. I think part of it is that it's still just an 8" sub. I also think the stock box has too much volume for the size of the speaker. Heck - the box for my 10" Type R has less internal volume than the stock box. Next I time I have some extra time to kill I'll pull it back out and fill some of the space in. Replacing it with a 10" Alpine Type R in it's own box with same amp was worth every penny!!! (especially considering it cost me nothing, as I already had it from my last car) The new sub sounds awesome, and adds just the right amount of bass.

wannabang Posted May 20, 2013 Report Share Posted May 20, 2013 Did you put the Alpine in the stock location? I'd love to see pictures of that. Quote Link to comment Share on other sites More sharing options...
