You do not need to set any HPF for the woofer unless you have a subwoofer.
If you have a subwoofer set an HPF for the woofer between 60 and 100Hz.
Dear Mr Navin
I have one query. does using 4.1 configuration and bypassing filters for front and rear channels help improving the sound quality? filters would be used for subwoofer along with the dsp. the factory music system might already have inferior dac and and if we add filters on top of it ..will it decrease the quality further and remove some of the frequencies.
do you suggest using full range output for speaker and use passive filters in 4.1 mode vs the active tweeter and midwoofer ( sort of bi amp config )
I am also exploring the option of adding pioneer
DMH-Z5290BT

please suggest

I prefer to use only 1 set of filters. Either in the HU or in the DSP (usually, the DSPs have better filters). Not both.

Wonderful thread and tons of technical information discussed in detail. Thanks to all sharing their knowledge and helping car audio lovers on their queries.

I recently purchased Hyundai Verna diesel sx(o) and I would like to hear better music as I got spoiled by my previous car Fiesta Classic audio setup.

A little background so that might help here. Fiesta Classic bought was a used one. I love rock music hence Ford audio CD did not sound interesting so with help of few friends into car audio upgraded the car audio.

single din - Pioneer 80PRS (stock Ford was 2-din)
Front stage - Focal P165 speakers
Rockford Fosgate Power T-400 4ch amp
Zapco monoblock amp
Audiofrog 12" sub woofer

Installed at Powezone years ago and the sub woofer at technocrat.

I bought most of the components at various period of time due to financial constraints. Only in 2018 got the last piece - sub woofer set up completed.

In 2020 sold Fiesta and bought Verna. I have removed the music system and replaced with Ford stock that came with the car.

With warranty and someone said Verna stock HU might have something connected with ECU hence, thought would retain the stock HU. (correct me if I'm wrong)

I was advised to buy Dayton audio DSP to sound better with stock HU. My known friend was coming from US hence bought one.

Has anyone set up DSP with stock HU? Since I have focal, amps and subs already, can I go ahead and install them along with DSP?

I don't think there is any such thing. I've seen many replace OEM HU's for the poor audio quality. I'm myself getting Pioneer HU for my Creta SX(O) as I value audio quality over looks.

As you can see on the input side of the DSP, there is a Molex connector, that's where the High-level inputs will come into the DSP (IF you are using stock HU) or else pair of RCA's (IF using aftermarket HU).

You can go ahead install the setup with the amplifiers and subwoofer.

Default Re: Upgrading your OEM Car Audio using DSPs (budget version)

I am upgrading the audio in my Global Fiesta (2014) and planning to retain my HU as I believe it is connected to the MID. Am told if I go for a good aftermarket HU from Pioneer / Kenwood / Alpine, I need not have a DSP but if I retain the HU, then its better to go for a DSP as I am looking for a SQ install.

I see the entry level is probably the Pioneer S1000 @ 10K and then RF model around 30K, MiniDSP @ 25K, Dayton DSP 408 for similar price and Helix DSP Pro which is a lot more expensive. Which among these are really good for a 2 way active set up? Am not yet fixed on a speaker, and am looking at options from Hertz HSK series / Rainbow etc.

Is Helix Pro one of the best? I dont mind shifting the audio to my next car whenever I buy the new one, so can spend a little higher than budget stuff if its really worth it.

By 2-way active, is it a pair of 2-way components at front + pair of coaxials at rear + subwoofer all run directly from their respective amplifiers?

If you are in a tight budget get the Dayton Audio DSP 408. Else you can look at Mini DSP 6x8. But if you can spend, look at DSP's from Helix. AFAIK, in Helix DSP list (India specific), you have 4 choices viz., DSP MINI (₹45,000) with 4 inputs and 6 outputs; DSP.3 (₹59,999) with 6 inputs and 8 outputs; MK2 PRO (₹99,999) with 8 inputs and 10 outputs & Ultra (should be around ₹2,00,000) with 8 inputs and 12 outputs.

Dayton Audio is an entry-level one that will help you get the output without breaking the bank. MiniDSP is a mid-level one and Helix is on the other end of the spectrum. Since you want to retain OEM HU, get a DSP that accepts both high level (speaker level) & low level (RCA) inputs from the source unit. Dayton Audio, Helix and MiniDSP all have these options so depending on the budget, get the DSP you like.

Thank you! Yep - I'll be going for front components and will drive it using a 4 channel amp & retain the stock rear coax most likely. The sub woofer is already installed and powered by a JBL Mono amp.

How much is the Dayton DSP?

Online, you can get it for as low as 15k INR. That's without Bluetooth adapter or wired remote- both of which you can skip if you don't like to mess with dsp settings often.

By the way, I'm in a similar situation - got JL Audio M600/6 amp, DLS R6A components and a DIY subwoofer from previous car. Sold 80PRS for Dayton DSP. Ofcourse car is a Verna . Planning for a 3 way active install and still thinking about mid range driver options.
