[@dreortiz2237]

Thank you! This helped alot 👍

[@jeremyurban6977]

So weird that you just posted this video today. I swear I was driving home blasting my music and thought to myself man I should really install a sub in my second gen 3 sedan. Then I saw this video. Thanks

[@ColtonRichter]

You should install a sub in your GenPu 3. I said it, you have no choice.

[@tomaspumphrey1797]

Super awesome video I just bought a Mazda 3 2010 and I have the sub amp and wiring kit. I was wondering if I need to buy a new radio if so what would you recommend?

[@sheesh6579]

Would you need a POC to connect the rcas to a factory head unit on a 08?

[@khyzn]

hey man, whats your headunit tune like? i not long done an install in my partners car and its just not pumping how it should, everythings all wired up properly and the sub and amp are good as we’ve tested in other vehicles but i’ve been told its to do with the headunit

[@ColtonRichter]

Could be, crank the bass on the headunit 😂

[@epicethansxx4406]

Thanks alot

[@drizzycris9936]

What kind of screen should I get for my Mazda ?

[@inserthenamehere8744]

I may have bought 4 subs and they fit, however because of this video my car proceeds to shake a lot. Anyway thanks for the tutorial.

[@ColtonRichter]

Haha cheers

[@paulomello7850]

I have an 09 mazdaspeed 3 w/ the factory Bose system, I assume the install would be fairly similar. Do you know of any differences?

[@ColtonRichter]

You need some sort of splitter to wire in with the factory system

[@paulomello7850]

I’m new to car audio, do you have any brand recommendations and specifically know what wire that is I’ll need? I can’t seem to find much out there for instructions on my car.

[@ColtonRichter]

There's a few forum write ups on it

[@pavanrajram5869]

hey man how do you retain climate control info on the little red lcd screen

[@ColtonRichter]

I don't think you can, i'm not entirely sure

[@jjeroen]

So i did everything but i dont know why my amp lights are not turning but theres voltage in it can someone help

[@harrypestell4440]

When do you reckon you’ll do another “rating subscribers cars” video? Very keen to submit my 2011 🤣

[@ColtonRichter]

Well! Since you brought it up, maybe i'll make a year 2 version once we get close to last one's upload 😬

[@rgskiing5070]

So if I have a stock radio unit then I would need a line output converter to plug in my rca cables?

[@ColtonRichter]

Correct

[@lifeclip9878]

Hi Im about to try an 8nstall (fist time) but when I test the equipment ie amp and sub at home using a 12v plug adapter the audio works but amp goes into protect mode the moment too much bass kicks in? Any idea why this is will it still do this if its grounded in car?

[@ColtonRichter]

Uhhhh if I had to guess... i've never tested car audio in a house 1. You're either overpowering the amp 2. Not grounding properly in a 12v plug 3. Something just seems hella' fishy about powering that stuff with a plug adapter

[@samlcyo2]

If anyone else is reading this, do NOT use a cheap AC to 12V adapter to run car amplifiers... Car amps usually require much more power than those can handle. You have to match your amplifier's power needs to your power source. For example, I built a "portable" high power sound system for outside use, and it required about about 600 watts of power. So I got a 700 watt 110V AC to 12V DC power supply and it runs just fine! You could in theory use that cheapo adapter to make sure everything turns on and is working, but you cannot turn the volume up. That why the amp goes into protect.

[@cris2valve]

what if you have a subwoofer setting on your radio and it’s turned off. will that cut power to your sub? i’m just trying to troubleshoot some things

[@ColtonRichter]

No, your radio does not control your amp power.

[@rownenmanning6870]

Can you do one ina gen 4

[@madschrono9891]

How did you Connect your phone to the radio? Did you buy the Pioneer radio that comes with Aux?

[@ColtonRichter]

Bluetooth

[@madschrono9891]

@@ColtonRichteralright thanks🙃

[@xbmarc]

Not going to lie, if the finished product is the picture in the thumbnail, you should only take away some small bits if this pertains to your can and watch how clean it can be done with minimal extra effort

[@AdamSNook.]

the amp power on should have been connected to the blue wire on the back of the stereo called r e m or blue amp wire on the stereo its self so the amp only comes on when you turn the stereo on not the egnition otherwise if you dont want the stereo on the amp will come on anyway when you turn the key

[@ColtonRichter]

Ah, didn't know what that blue one was for 😂

[@gtavlovers3354]

Hello do you know i lot about it cuz i wanna connect a subwoofer in my 07 mazdaspeed 3 but it is stock radio, I want to know how it can be connected in my stock radio.

[@AdamSNook.]

@@gtavlovers3354 you can run rca to speakers into the amp omn a stock radio

[@gtavlovers3354]

@@AdamSNook. can you do a diagram for me how it can be made.

[@AdamSNook.]

@@gtavlovers3354 on most car amps you have a high input aswell as left and right phono you connect your speaker wires from left and right speakers to the high power input on the amp so your stock radio as ither 2 channel or 4 channle 2 run all 4 door speakers you just need to tap from them to the high input on the amp

[@breaddonor276]

What aftermarket radio do you have?

[@ColtonRichter]

Pioneer AVH 291-BT

[@brianluck84]

Damn i feel old, when i got my first car (2000) subs and amp install was a right of passage. Buying the biggest sub and amp you could fit. Headlights dim with the bass, capacitor installs. These days its rare if i hear a vehicle with base hitting let alone just loud music.

[@ohnaw223]

Fax some small ghetto towns still got it tho

[@ohnaw223]

Back in the days of paul wall

[@mazdaspeedg2380]

Need to do this but need a amp and a rca converter don’t want to buy a aftermarket radio

[@ColtonRichter]

Also need to bypass the Bose amp!

[@peterjohnson9438]

What I did was to keep the stock head unit and replaced all door speakers with JBL Club speakers, with an additional tweeter kit installed in the wing mirror bolt covers. For bass, I got a thin 12" active subwoofer, taped the vottom full of velcro and placed it under the passenger seat. I ran audio cable vampire clipped off the speaker wires behind the head unit and power through the passenger side firewall gromit, with remote power piggybacked from a fuse in the cabin fusebox. All the cables are run under the door threshold and poke out from near the seatbelt bolts. Ground is taken from a seat bolt. Finally, the stock head unit got paired up with a Bluetooth module that pretends to be a CD changer, and music is streamed in over Bluetooth from a cheap tablet. That's the only less-than-clean bit of the entire rig. All in all, I'm happy to have a hugely improved audio quality while keeping the car looking stock. That said, a new head unit would improve sound quality, but I want one that'll connect to the internet and run both Spotify and Maps so I can lose the tablet - those head units are just pretty hard to come by.

Can you connect a subwoofer Mazda 3 2008 stock radio?

[@ColtonRichter]

Yes

[@Peter-jk9fx]

@@ColtonRichter do you need anything else or can you just use the wiring kit?

@@Peter-jk9fx if you didn't find out yet, you would need to use line level converter.

what do i do if my amp doesn’t have a sub out?

Why don’t amp installation kits come with speaker wire? Really annoying

[@ColtonRichter]

Amp install, like a subwoofer wiring kit? Every kit i've bought comes with speaker wire!

[@rgskiing5070]

@@ColtonRichterI bought the EFX PA8BX amp wiring kit off Crutchfield. It came with power, ground, rca, remote, and accessorys but no speaker wire. Wasn't a problem I went and bought some 12 gauge speaker wire from the hardware store but you would think it should come with the kit. Seems that's how most kits are off Crutchfield besides the kits over $100😵even though they say the kit has everything you will need to wire up your system.

[@jimbob5892]

the connectors you used suck and should only be temporary use only (remote wire) unless they have improved in the past 20 yrs

[@Omgkhii]

You said “basically” OVER 30x in the old video. Came here just to stay sane

[@jimbob5892]

the amp is not straight

[@Sincere410]

Please be aware that mazda is not a new 1 lol

[@motabaiofficial7776]

I brought one back to life and they’re bad ass, especially if you turbo them

[@KdubTraX]

where did he ground it to?

[@ColtonRichter]

Seat anchor.

remote wire runs from amp to the sub? hmm...

Amp to radio or any power signal.
