  1. System Design: Help Me Choose Equipment For My Car
    Hello everyone, this post is to walk through the build I am planning to do and get some feedback or have some discussion, it will be a little bit of a longer post but I am trying to give as much detail as I can. The vehicle for this build will be a Hyundai Genesis Coupe 3.8 R-spec. Sound...

    I'm getting ready to make a box for 4 Sundown U-65SW 6.5in subs. Currently with a design that fits under my rear seat I've got a total of 2.08cuft and will be 1.9cuft with the displacement of the subs. I'm looking to tune to 35hz and the recommended port area for the subs is 4-5sqin each, so...

    I am looking to purchase a DSP. Either Helix or Arc Audio and I need a tuner who is familiar with these two in the DFW area.

    Hello folks. Been reading and watching many videos before actually attempting to set up this thing. I see that it requires me to do some initial setup to turn down the tweeters, etc. Does anyone have a step by step guide to initial tuning to have it turned way down? I don't want to risk...

    A lot of people talk or don't talk about Op Amps - they either install them or don't. What is the purpose of Op Amps? How do they benefit a Sound Quality Competition Vehicle? What is the alternative? Thanks in advance.

    I am a relative beginner in car audio. I've done aftermarket setups in 3 of my cars now, and I'm working on my 4th build right now which I'm taking much further than every previous build. I'm getting to the point where I really want to understand everything about sound, and car audio. I want to...

    Hi, I have a Ford with a 10 speaker B&O system. Currently, I have a Helix G one amp with a shallow sub already installed with a 4 awg OFC wire. Now, I have a PAC AP4 FD31 in the rear, using which I want to bypass the factory B&O amp and connect to a Helix V Eight amp in the rear spare tire...

    If I EQ individual drivers and then try to auto eq the pair, it seems like the software is just wiping the original l/r EQ settings and adjusting the pair. Is this what is happening? I've read several threads but can't seem to find that discussed.

    I am reimagining my audio setup which consists of the following; Helix Dsp running Steg Tweeters, Scanspeak 4" mids. Peerless 8" in doors and 2 JBL fuse ( one fuse "in half") under my seats. My question is, can I run the fuse mono? or will this mess up my tuning. I can squeeze a bit more...

    Hello! So, for my intended dream audiophile build (theoretically) there's a grand total of 14 dedicated channels around the cabin. 6 of those being hifi 3/4" tweeters & popular opinion states that as an awful idea. Not sure I understand the problem? In my mind if Maria Brink can put out a treble...

    So I've read that a system should always sound decent with the sub off, which makes sense. But is it safe to say that a system always sound decent before tuning? Or have people ran into situations where a driver sounds like garbage until EQing made it great?
  14. Technical & Advanced Car Audio Discussion
    Everyone seems to have their own technique when it comes to measuring their drivers when tuning. What is yours? Getting consistent and repeatable measurements can be difficult. And that can cause a tune that sounds awful to the ear look great on RTA or sound great and look awful, depending on...

    I'm working on getting better at tuning and figuring out what to pay attention to, and what to ignore. So I'm looking for some advice on what to do when it comes to reflections. As an example, in my car there is always a dip around 600-750hz in my passenger side midrange measurements (left hand...

    Hi All - I’ve been reading here for a while and never posted. I’ve been doing my own stereo installs since the 80’s and this year i took the ultimate leap of faith and bought a ton of gear for my new truck and had it installed due to a neck surgery that has me limited in my mobility. Problem...

    Hi everyone, This is my first post here so I'd like to start off by saying nice to meet you all. I have had a sealed enclosure in my ute for a good 6 months now. I went sealed as I thought I was very constricted for size having only gone off forum research from others previously taking on the...
  20. General Car Audio Discussion
    I am attempting to model my full system (i.e sub/ mid bass/ mid range/ tweeter) to align the phase based on crossover points of each driver to get a baseline before tuning. That said, I have found no discussion on the difference between the System Overall Transfer Function Phase graph and the...
