This is for the 2018 Hatchback, but likely similar for all generation 3 models. Sorry in advance for the long post. First some simple questions. I would appreciate informed first hand responses instead of the typical "I read somewhere..." Question 1: What is the efficiency of the non-Bose...

I have a 2010 3s non-Bose stock stereo. One of things that has bothered me the most about it is the excessively boomy mid-bass. I'd like a cleaner bass sound but without a sub. Is this more the result of the headunit, or the speakers? If going the speaker route but keeping the stock HU, I...

Hi everyone, I have been hanging around the site for about a year and a half now and while i found out a lot, when it came to replacing the audio system I could never find what I was looking for. I have installed a Rockford Fosgate 5 channel amplifier into the 3 and I could not be happier. This...

Hi, I've managed to confuse myself around all the bose/non-bose component/composite/crossover jargon and could use your help. I have a 2016 3 with the 6 speaker non-bose system. I'm looking to do a relatively easy upgrade - meaning no new amp, and preferably no crossovers. Would like to...

Hello, I thought I would share this hacky weekend bodge I did to get direct low level audio output from my factory 2010 Mazda 3 non-Bose receiver. This isn't really a tutorial or anything but hopefully someone will find it cool and nice. I wanted to upgrade the stereo in my car for maximum...

I don't have the opportunity to do an intensive side-by-side between the two systems. All I care about is a quality 2.0 system. Will only use the rears as fill. Don't care about fancy-schmancy surround simulations etc. Emphasis on clarity and imaging. No plans to upgrade. So which one is...

Looking to tap into the speaker level inputs, anyone got an answer?

Hi folks, I have a 2016 6 (non-Bose) - figure there are more infotainment system peeps on here than on the 6 forum. I noticed when checking the frequency response with my Rockford Fosgate 360.3 (electrical signal, not acoustic), it is not flat. Particularly, there is a sharp drop-off in low...

I've gotten so much benefit from the posts on here, I thought I would post my experience in upgrading my stock 6 speaker system to all Infinity Reference speakers. I have the non-Bose (Canadian) 6 speaker Infotainment system in my new GS, not sure how this model translates in other countries...

Thinking about installing new door speakers on my 2016 Mazda3 isport (non-Bose system). Started thinking about wattage of stock head unit, anybody know how much power it puts out?

Non-Bose distorted/clipping audio Is distorted/clipping audio a common problem with the non-Bose audio systems? I generally listen to podcasts and audiobooks with my car. On my previous 2004 Mazda3 S, I didn't have any issues with playback (other than not great sound quality on the stock...

Hey, so I just purchased the parts for my new stereo. I'm doing a complete install with a 5 channel amplifier, component speakers in front doors, coaxial speakers in rear doors and a sub in the trunk. If curious, I'll be using an NVX JAD900.5 amp to power Alpine SPR-60(C) in front / rear, with a...

I'm not sure if I'm lucky not to have the Bose system or not but it seems all threads relate to the Bose system. So for those that have the non Bose system just a few questions: So far I have replaced the rear speakers with Focal ISC 165 and Dynamatted all 4 doors . This has made some...

I installed some 6.5" Polk dxi651 on my 14' iTouring with the non-bose system and they have less bass than the stock speakers. I'm not great at soldering, but they seem to produce sound -- I'm just wondering if I screwed something up installing them or these speakers kind of suck or they really...

Hi, Been looking for details on speaker wiring for my car. I have a non-Bose system with infotainment. I plan to tap the rear speakers. Does this system have a TAU or should I connect behind screen? Can some help out with which specific wires to tap? There are a few write ups on this forum...

Hey folks! I have a 2014 iTouring 4 Door and just replaced my front door speakers today, using information from tmoi and others, thanks! BTW, I've been monkeying with car audio since the '80s, so this was easy for me - your mileage might vary! First, you have to pop your door panels off, this...

Hello all... I just did this upgrade to my 2014 i-Touring hatchback yesterday, and the result was amazing. This upgrade will be the most cost effective and stealthiest looking, and the sound will be loud and clear throughout the whole spectrum, unlike the typical amp and sub install. I was...

Finally got around to installing my Hertz ESK 6.5” Components. Took me a good couple weeks as I've been pretty busy and waiting on parts. Got some help from a friend during the install...The lesson we both learned from this install was to not buy eBay piece of sh!t 5x7/6x8 adapter plates (see...

I'm new to the world of Mazda3, having just purchased mine last week. I decided to forego the tech package because it would have required a dealer trade states away, and I definitely feel like the factory sound system is lacking. But in my searching, all I can find is information about the Bose...

I couldn't find much online help with saving the stock non-Bose head unit so I am posting what I did to make the stock non-Bose head unit sound pretty darn decent. I chose to do everything I could to keep the stock head because I really liked the look, layout and built-in functionality of the...
