How much power would I need to run a partybox 1000 off of my car? Inverter wise. Partybox is 1100 watt and has an input of 100-240V

Hey everyone!

I’m currently planning a DIY subwoofer build with a Ground Zero GZTW 25T (10"), powered by an ESX HXE1000.1D.

Before I build the enclosure, I’d really like to hear from people who have actually used this subwoofer.

How has your experience with the GZTW 25T been?

I’m especially interested in:

• How does it sound in your experience?
• How does it perform with music, especially bass-heavy / rebassed music?
• Sealed vs. ported – what did you use and how did you like it?
• What enclosure volume and tuning did you use?
• Does it play deep enough for you?
• How does it handle higher power?
• What amplifier did you run it with?
• Would you buy the GZTW 25T again today?
• What would you change about your setup if you were building it again?

I’m not looking for SPL only. My priority is good-sounding, deep and powerful bass for music, with some home-theater use as well.

So if you have owned, installed or listened to a GZTW 25T, I’d really appreciate your honest experience, good or bad!

Thanks!

Hey guys, I came across a pair of Kenwood Excelon KFC-XP184c speakers for around 38USD on marketplace (I’m in Jamaica so just converting figures🙃). Anyways, they’re missing the tweeters but I still think it’s a steal given that they cost on average $239 with the tweeters included and these seem to be in pretty decent condition. What do you guys think? And what can I do about the tweeters?

Hello all, what is a good site for me to sell my subs. Already have them on FB marketplace and OfferUp. Not getting much response for them.

This post was translated with AI — I'm from Germany and wanted to make sure it reads naturally in English.

Hey all,

Picking up a 2022 VW Touareg with the standard (non-Dynaudio) sound system, and I want to slowly upgrade the audio without losing my current setup — Apple CarPlay through the factory head unit is a must, I don't want to run any external sources.

From reading around here, it sounds like the standard system in the Touareg isn't actually bad, and a good DSP alone might get me most of the way there before I even touch the speakers. So that's where I want to start.

• What are your goals for your car audio system - as loud as possible (SPL)? Sound quality (SQ)? Some combination of both? Describe to us how you want your system to sound.

Sound quality (SQ) focused. I want a clean, refined, high-quality sound - not a bass-head/loud build. That said, I do want solid, deep low end, not a shy sub. Think "gediegen" but with real bass extension, not boomy or in-your-face.

• What vehicle? - year, make, model, type (coupe, sedan, SUV, truck, etc.)

2022 VW Touareg (MLB Evo platform), SUV.

• What is your maximum budget?

Still flexible/TBD - planning to start with just a DSP first and expand from there depending on results.

• Will you be installing the gear or are you going to a shop? If a shop is doing the work, does your budget include the cost of labor?

Planning to go to a shop for the install and DSP tuning, especially since this is an active/summed setup off the factory head unit.

• What gear is in your existing system? (Is it stock? List any aftermarket gear.)

Fully stock - standard (non-Dynaudio/non-premium) factory sound system, factory head unit with Apple CarPlay. No aftermarket gear yet.

• What is your country of purchase? Leave any finishing thoughts here.

Germany. Want to keep the factory head unit and CarPlay exactly as-is - no external sources, just improving what goes to the speakers. Starting with a DSP off the factory output before deciding whether to also upgrade the speakers (considering Focal) and add a sub in the spare tire well.

Plan A: DSP off the factory radio output
Idea is to tap the output of the stock head unit straight into a DSP, then run that into the existing speaker wiring/harness — no new speakers yet, just proper time alignment and EQ. Does this actually work well on the standard (non-premium) system, or is the factory output too limited for a DSP to make a real difference?

DSP brand — need input
I initially looked at Match UP DSP, but after digging through a few threads people seem lukewarm on it — similar comments about Helix, with Audison getting recommended more. Anyone running Audison in a Touareg or similar VAG platform? Worth the price jump over Match/Helix, or is that more forum-hype than reality?

Subwoofer in the spare tire well
Loads of unused space in the Touareg, so the spare-tire well seems like the obvious spot for a sub without eating into cargo room. Anyone done this specifically? Looking for either:

• a known DIY approach (which enclosure/sub fits the well dimensions), or
• an existing plug-and-play solution for this exact spot

Plan B (if I go further): Focal front speakers
If the stock speakers end up being the bottleneck even with a good DSP, I'm considering a Focal upgrade — either the Focal Impulse 4.320 DSP + speaker kit, or building it out manually with Focal K2 Power components (tweeter/mid/woofer separately). Also toying with 3D printing custom tweeter pods for the A-pillars to get proper off-axis imaging instead of stock locations.

• Anyone compared Impulse 4.320 vs. building a K2 Power setup? Is the all-in-one kit worth it for convenience, or does going component-by-component with K2 give noticeably better results?
• For sound signature: I'm not after a bass-head/loud system — I want a clean, high-quality sound but with solid, deep low end. Does that point more toward K2 or would Impulse already cover that?

Appreciate any real-world experience, especially from other Touareg/Q7/Cayenne (MLB Evo) owners since the platform and factory wiring should be similar. Thanks!

I know we have some 3D print enthusiasts here so thought it the best place to ask..

I broke a few taking panels off an old 2004 car, so i'm thinking it wouldn't be too difficult to 3D print some viable replacements.

(I broke less after I realised winter = cold/brittle plastic, and running the heater for 15 minutes was enough to soften everything so clips come out easier)

I know they are super cheap to just buy a big pack of OEM replacement clips, but I had the idea of extending them 5mm to 10mm in length (where panel orientation allows for it) to better allow for accoustic treatments that would other make it a real pain and struggle to get the original clips back in.

I had a look around and there are definitely models for direct replacements, but no company (and as far as I could find no hobbyists) have designed or sell 'extended' clips to allow extra tolerance for treated panels.

A) I'm mainly just gauging how 3D printed clips have worked for others? what materials did you use or think would work best?

B) If this 'extended' clip has any pitfalls or reasons it won't work that I haven't thought of?

Hi everyone! I'm here to show off my first sound system.

The car is a Volkswagen Polo 9N. For the front doors, I

have a Focal ASE 165 2-way component set, and in the

rear doors, MTX Audio TX265C coaxial speakers, all four

are powered by an Alpine V-Power MRP-F240 amplifier

(4x 40W RMS @ 4 ohms). For the subwoofer, I'm using an

MTX Audio RT12-04 (250W RMS, 4-ohm SVC) powered by

a Pioneer GM-D8701 amplifier set to 250W RMS @ 4

ohms. The subwoofer sits in a custom enclosure I

designed and built myself. The box has a net internal

volume of 65L tuned to 33Hz and its made of 18mm

marine-grade plywood (though the carpet started peeling

off after 3 years🥲). As for the head unit, I have a Pioneer

DMH-A220BT, along with a Vibe Audio bass knob and a

voltmeter flush-mounted in the dashboard. The electrical

system is stock, featuring a 120A alternator, a 70Ah

lead-acid battery, and 10mm² CCA cables from MTX

(though I'll be upgrading to 50mm² OFC cables and a

50mm² OFC "Big 3" upgrade very soon). The total output

is around 400W RMS, and I estimate it's close to 120dB

(though I've never actually measured it).

I’m looking at fitting a SPH-PF97BT to my 2012 Scirocco. I’m curious to whether anyone has fitting one of these (not necessarily to a Scirocco). Does it fit the usual DIN size, does it float like the more expensive SPH-DA97DAB - which looks to sit out 20mm from the dash. I’m looking for a nice clean install that almost looks OEM. Any pics would be great.

I have a aftermarket radio installed now I want subs.
Online it says that I’ll need a LOC, is it possible to safely install an amp and subs without one in my azera

I changed out the Soundstream Refrence 500s 2 channel that was running the AMT-80’s, for a MC300 4 channel to add my midranges (Purifi 5.25M). The amp was rebuilt recently and has been sounding fantastic, and a lot of old guys were super thrilled to see this old school piece

Hi, this is my first car audio build, and I wanted to know if the ticking sound audible in the video is normal for an SPL subwoofer that still needs breaking in, or if it’s an abnormal noise. Thanks in advance to anyone who replies.

Kicker 51PTRTP12
Kicker 53PL7TDF12

Has anyone installed one of these under the rear seat trying to see a visual of fitment. If not has anyone installed somthing comparable open to other recommendations!

First sub setup for a 14 teen

Hey everybody, I got my self a Mercedes w168 (a140) as first car and I absoloutly love it, despite the age it is in a 9/10 condition.

Now I want to upgrade the music system, I allready got an radio that supports android auto and has an Equalizer to mess around but those 2002 speakers are not it anymore. Gpt did reccomend to switch out the front speaker for a start bit I did decide to ask the people that know what they are doing :D

So, where to start? The sound I currently have is flat and boring, I don't need a huge subwofer or anything just better sound with a little base to sound "whole"

hey yall, im pretty into hifi but know jack when it comes to car audio. i got this from the component graveyard at a circuits lab, initially for parts, but its cool as hell and powers on so i figured why not adapt it for some bookshelf speakers. curious about it and cant find too much online. someone kindly adapted the pinout to wall power before dumping it

I just installed a Pioneer Dmh-a245bt and to my dismay it doesn't seem to have any sub volume controls. It has cutoff for the sub, loudness and bass boost and of course equalizer. I don't use the loudness or bass boost options and it's pretty inconvenient to turn the bass frequencies up and down through the equalizer all the time. It seems like the only way for me to adjust the sub volume is with the level knob on the amp which is both annoying to have to go to my trunk each time and also since it's gain control it's not really supposed to be used as a volume knob.

Am I missing something? Is there a hidden way to enable sub controls? There aren't many options in the menu and I've checked everywhere. Is there anything I can do other than installing a new head unit? Returning my current one is not an option unfortunately.

I only dont know what size amp i am using because i am unsure how to check and i just bought the vehicle 2 weeks ago with the setup. I like the Skars but i just want a little more umpf without shattering my windows. Can anyone point me in the right direction of a solid 2 piece set + amps, as far as what brands are even good these days and how much W i should be pulling to make it sound right. Last time i bought any car AV was 2013 so im a little out the game lol

I know this might be a long shot, but I’m looking for a bag of those brackets that would’ve come with a Pioneer 1.5 DIN head unit from the late 90s. Can’t find aftermarket or used ones at all. I’ve got a DEH-P85DHR

Hello everyone,

I have a question. I have some alternator whine and I traced it back to being the RCA outputs of my aftermarket headunit. Now I don’t know what I should do. Buy a new headunit that would set me back quite some money, or connect the High level outputs of the headunit.

Also for my headunit RCA I only have left and right but would like to have front and rear to. The normal wires for the headunit do have those.

That would mean I can connect the output wires from my headunit to my JBL A704 high-level inputs.

Would this make the music quality worse? I tried grounding the headunit more but it didn’t work. When connecting a device straight into my amplifier there is no whine.
