Audio tuning totally changes the sound in a car | Helix DSP Pro MK2 

No stage xpander nor clarity xpander used. Centre speaker disconnected. The bypass only affects the EQ so it wasn't even a full bypass.

​@@soundtech7989what speakers would you get for trap music. I want to hear everything through my music

@hapexamendar1093 I'm late to the party, but a decent DSP can provide the Single Largest Improvement in SQ to ANY car audio system....MUCH more than any differences between any two decent amplifiers, and much more than the differences between speakers. While the level of SQ that you can ultimately achieve will be limited by the Quality of the Speakers and Subwoofers/Enclosure (and their PROPER Installation), when PROPERLY TUNED by an experienced and knowledgable tech, a good DSP unit will allow you to Extract and Experience THE FULL POTENTIAL of ALL of your other expensive gear! We need to remember that a "DSP" doesn't just provide a "Global" EQ (which on its own is very important), but the DSP can provide INDEPENDENT P-EQ for Each Channel, which is incredibly important in order to MATCH the Left side Frequency Response to the Right side Frequency Response, At Your Listening Position. This alone is HUGE. However, a DSP also provides OPTIMIZED Crossovers, for both speaker protection and ideal Frequency & Phase response between all of the speakers. Non-adjustable Passive Crossovers are a Compromise in that they need to be designed as a "One Size Fits All" solution, which is NOT ideal. The variable distances, spacing, and aiming angles of each speaker due to the widely different mounting locations in different vehicles severely affects the Phase, Timing, Frequency Response, and Transition from speaker to speaker in relation to your listening position, and Passive Crossovers CAN NOT account for or adjust for that. Every vehicle is unique and different. In addition, Independent Time Alignment for Each Speaker is ABSOLUTELY NECESSARY in order to achieve Realistic Imaging, a good Soundstage, and "UPFRONT Bass" in a vehicle where we cannot sit perfectly centered and equidistant from the Left & Right speakers like we can in a home audio system. While the Demonstration in this video is generally good and we can in fact hear a significant difference in the Sound Quality (for the better) when the DSP's EQ correction is activated, the quality and limitations of recording the system with an iPhone or smartphone WILL NOT allow us to hear the full scale of the improvements, including those in reagards to the improved imaging and soundstage. Without a DSP that has ALL of these different tools that are INDEPENDENTLY ADJUSTABLE FOR EACH CHANNEL and that are combined into one relatively compact package, we just cannot acheive anything close to a true high-end SQ system in a vehicle. Search for the SQ Competition/Event schedule on each of the different Car Audio Competition organization's websites to see if and when a SQ Competition will be happening near you. There is IASCA, MECA, MASQ, SQology, and EMMA. Try and go to one of these events (go early) and ask around for what Top 10 vehicles you should listen to first. Most of the competitors are happy to give you a short demo as long as they are not waiting for a SQ Judge to Evaluate and Score their system. I think you'll be blown away by what you hear. :) You can ask them if they have a "Before & After" tuning preset as well.
