The amplifier is a box of trash and honestly, I'm grateful it hasn't burned down my car yet.
I set the passes to full on amp and XO is on the Head Unit.

The front and back speakers are both on CH1 and CH2, the sub is bridged over 3 and 4

Since it's a pretty small enclosure, I expected the lows to be nice and hard, instead of loose and all over the place.

It doens't handle anything above 60Hz very well. It keeps going brrr brrrr and irritates, but if I set the LPF to 60, then it hardly ever does anythingCar Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!-pio.jpg

Recommended enclosure for sealed application is 0.4cu.ft.

I think that crossover is not correct for this subwoofer. As per the owner's manual for the Pioneer TS-SW841D the Fs (Resonance Frequency) is 67.5Hz so the LPF should be around 135Hz (LPF = Fs x 2 is the general rule). Try setting this and do a test play.

Nominal Power: 120W

Re: Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

Hi ICE enthusiasts.
I have a question.

I came across an Instagram post for a custom made enclosure which houses 4 speakers and 2 sub-woofers.

What are the advantages of such a unit? Can we remove it and use it as home entertainment when not in use in the car? Does this sound better than installing the components at their proper places?
Why else would someone waste their boot space?

Re: Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

My wife's Celerio has the following set up:
- Blaupunkt Hamburg HU.
- JBL front components.
- Blaupunkt rear coaxials (door mounted).
- Sony 4 Channel Amp (currently powering the front components only).

Now I'm looking to upgrade to something decent. Sound Quality is a priority. My requirements are as follows:
- Touchscreen (Android auto if sound is decent otherwise something else).
- Front and Rear Components.
- Underseat Subwoofer.
- Bluetooth connectivity / Android Auto (Don't need Apple CarPlay).
- Rear camera.
- Damping for doors.

Budget 30-40K. Is it doable? Do I have to do it in 2 stages? Can I retain any of the existing set up?

New Android HU will be between 15-20K easily which will have rear camera input as well as Bluetooth and Android auto too.

I'll suggest components in the front and coaxial at the rear. Options are a lot in terms of speaker choices. For speakers look for an allocation of 15-20K for front and rear set.

Damping will need 10K allocation and another 10K for underseat active subwoofer.

Look at the classifieds section for good deals on amplifier/speakers/HU's.

In the link, this setup is installed in a Scorpio which does not have speaker provision on the rear doors. So it still makes sense because stock location is on the boot door. Also, this setup will make work easy for the installer as all speakers are at one place.

For that, you'll need DC power supply (or AC to DC converter) to power up the amp at home. But moving such a large enclosure would be too much of a pain and it won't sound great either, as compared to a dedicated home audio setup.

I'm pretty sure it does not.

Lack of awareness.

Re: Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

I managed to swap the Focal coaxials on the front door with JBL components. Long story short - the Focal coaxial on the rear left door gave up, so swapped one from the front and put in a pair of JBL components in the front doors.

Since I had to use spacer rings to accommodate the midbass in the front door, I got the spacers fabricated using a 1/2" thick chopping board made of polypropylene material. I was averse to using MDF spacers since I had read about instances wherein the MDF spacers become soggy over time after soaking in water.

Got it cut into rings from a dude who specialises in these switchboard fabrication works. You know the older arrangement which requires a laminated plastic board that holds the switches and sockets.

I was also skeptical about how well would this material be when screwing into the door's sheet metal and while screwing the midbass into it. But the screws were secured perfectly - tight and doesn't keep spinning infinitely!

The local accessories installer whom I'd approached for the work was a bit flummoxed when I handed them the spacer rings. Asked me a lot of details.

Re: Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

I don't have much knowledge on audio upgrade, just planning on a basic upgrade for my S-Cross. How about damping all four doors and speaker upgrade with budget of around 30k ? What are the recommended options ?

Thanks!!

I'd say get a pair of Infinity kappa components or Polk audio components in the front and infinity reference coax in the rear doors. Both should cost around 14k. Add in CTK damping for all 4 doors for 10-12k (It depends on the brand and the number of damping sheets used). This is a standard upgrade and if you want more then add in a 4 channel amp later to drive the 4 speakers better and louder. Usually the company head units dont offer great audio like Pioneer/Sony etc. so that can be thought of later too.

Re: Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

Hi,

I am looking for some advice on upgrading music system in my Tata Nexon XE (2020).
Right now, I have Android Head Unit, Rockford R1675-S component speakers in front gates, Alpine SPJ-161C2 6" Coaxial Speakers in Rear gate.
I am happy with the sound quality and output (volume + clarity).
But what I found missing is some bass.
I am not fond of high bass that can be heard outside the car.
Just want some decent bass which is lacking as of now. Also, the doors in my car have not been damped.
Should I go with an underseat subwoofer? If yes, any particular recommendation?
Will really appreciate the advice from experts here.

Get the four doors damped, if possible. This itself will make a lot of difference in terms of sound quality.

For bass to be added to the current setup, I'll suggest you to look at Blaupunkt GTB 8200a active subwoofer - LINK

Re: Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

Guys,

I am not too satisfied with my car audio install. But every time I go to the installer to complain he just tells me it sounds fine and I come back with no resolution.

I think the sound my car puts out is muddy. Its not as clear as I want it to be and the bass is not tight enough. I also feel that some bass leaks from the mids. I have tried many changes on the HU settings with HPF, LPF, etc, but to no avail. I also feel that the tweeters on my car overpower the mids. The only sound I hear is from the tweeters and it totally drowns out the mids. I even tried to cut tweeter gains by as much as 8 DB but of no help. I mean, sure, no tweeters aren't as harsh as before but they till drown out mids.

The installer has also set HPF and LPF on amp itself so I guess whatever I do on the HU doesn't really do a lot of different.

But I cannot go to him again as I have wasted enough time. I was wondering if you guys could help me with this?

Do you know an installer you trust who could just review my set up and help me tune it better, may be? I am obviously ready to pay for this.

Please help a man out in dire need of some crystal clear tunes in his car.

Please list out the equipment on the car so it can be easy to help you out.

Since the amplifier has LPF/HPF set, any more adjustments done on the HU will add up to the crossover setting and spoil the output hence either set it on the HU or on the amplifier.

Hey Anurag,

Thank you for your response.

My components are Vibe Blackair 6c-v6b, subwoofer is Vibe Pulse 10" and Cadence Momentum CSA1000.4 amplifier.

I get your point about adjustments either on the amp or the HU but I guess its not that simple.

Amp is located in the boot and the markings on it aren't digital. Using a screwdriver makes it difficult to set HPF/LPF to exact numbers. Bypassing on amp and setting on HU opens up another issue. What is HU settings get reset? Then components and sub will blow up. I thought setting on amp acts as a buffer against such mishaps.

HU getting reset when the battery is disconnected is a common worry and I feel in current generation aftermarket HU's they remember settings if the battery was disconnected only for a short duration. If longer than 3-4 days, then the settings will be reset.

Since the amplifier doesn't have specific markings and are not accurate, set them on all-pass and use the settings on the HU only and see if there is any change in the sound quality?! (for trial purpose only!)

Can you list what settings are you using for each speaker set?
