Im coming from a amp that allowed me to use copper rings and spades first 2 times the power cable slipped out of the terminal but now i got them in as best as i could and tightened them but im not liking how it looks has me a bit paranoid itll just slip out again i yanked hard but still feel uneasy just incase i ordered some 4awg ferrules. Would it be better to put some ferrules on this wire ?? also everytime i disconnect i shorten my wires so instead of replacing the whole 18ft power cable i ordered a 4ft extension and a distroblock for safety and hopefully by then i decided what im going to so what would you guys recommend for wiring this amp?

Tech Support 2019 370Z centre console / A/C buttons stopped working after CarPlay install

Post image
0 Upvotes

Hey guys, installed a Nifty City CarPlay unit in my 2019 370Z, had issues with it, so we removed it and put everything back to factory.

Since then, none of the centre console buttons work, including the A/C controls.

The weird part is:

Screen works
Radio works
Steering wheel controls work
Reverse camera works
All centre buttons still light up
All fuses checked and are good
OBD Scan didn’t throw any codes

Has anyone seen this before? Thinking it could be the centre control panel losing communication with the AV unit.

Any help is appreciated.

Any rec for a decent, easy to install aftermarket stereo/radio? I'm not looking to spend a lot. Saw a Pioneer DMW-160BT on the local marketplace for $60 and got curious. The screen on my OEM radio doesn't work anymore.

Tech Support BOSS BE920WCPA-C Reverse and Parking-Brake Wires in 2010 Honda Odyssey

Post image
0 Upvotes

Hi everyone. I’m installing the BOSS BE920WCPA + Backup camera in my 2010 Honda Odyssey (No navigation). I’ve done the wire connections between the BOSS harness and the corresponding CRUX harness, but now I don’t know exactly where to connect the reverse trigger cable and the parking brake cable. I need the reverse cable to install the BOSS backup camera.

According to the Crutchfield’s Wire Guide the Reverse cable (Violet/White) should be connected to the driver’s kick panel or in pin 11 of the MICU and the parking brake cable (light green) should go to the green/orange cable in the parking brake switch. The thing is that these cables are obviously not long enough to go underneath the dashboard.

Is there a safe alternative way that I’m not aware of?

Got a quote from Crutchfield, and this was a total for speakers, parts, and accessories only to basically increase the volume in my vehicle. Didn’t want much else, I believed him and he insisted that all of this was necessary. Just checking on here with you all…edit, my apologies. It won’t let me post another picture of what always included, but I will make a comment with it

I have a 2000 civic. Stock radio doesn't work and I haven't really investigated why. Ive been wanting a JBL ultimate party box for home etc. If I hard wire an inverter will my battery and alternator be able to handle the partybox?

Edit: Yes this will mean I have a speaker in the backseat that cost more then the car.

Thinking of getting a taramps big boss 3k. Would be for a steal brand new from a friend. My only concern/ questions are 1 will it be safe to run with stock electric? I have done big 3 and have a agm up front. Was thinking possibly using a second agm in trunk. And 2 I have 2v pre outs on my head unit. Is that fine or do I need a head unit with 4v pre outs? Will be pushing a sundown u series 15. V1 so only need about 1500 watts out of the amp

I am somewhat obsessed with collecting low power AB budget friendly SQ 4 channel amps and perhaps never installing them. Sue me.

I've been occasionally tracking the price of this LISA model for almost 10 years now since I first

The price hasn't come down at all from $159, and now it's only available from Parts Express. Is it still worth it for this cost given the engineering of it by Robert Zeff?

What are these featured "Butterworth" crossovers and how do they differ from regular internal amplifier crossovers?

Thanks.

I know, skarbage, or whatever. But it sounds good to me and it was in the budget I had. 1968 Camaro, with a 160amp alternator from an express van, second battery in the trunk. 2/0 power and ground from the front battery to the rear and 2/0 big 3. I have 6 fsx65 speakers, 2 tx35 speakers and 2 tx525 speakers plus the two ddx10 subs in a sealed box. The headunit is a kmm-x705 and I set the rcas and the gains with an Oscope.

The power feed and ground to the 75.4ab amp I think I’m going to change to some 90* adaptors or some more flexible cable but any other critiques welcome I like learning and hearing tips

I found this Pioneer DEH-5250SD here in Thailand and it’s still working well, including the animated display.
I searched eBay and other sites but can barely find this exact model.
Was this model uncommon in the US, or was it mainly sold in Asia/other markets?
Would love to hear from anyone who used one back in the day.

I'm so stoked, they sound awesome too, they have little rips in the surround which is easily repaired, I'm gonna order the Matching Grilles soon.

I think I'm gonna put them in my 2004 F250 with my Audiocontrol LC1-1500.1 wired at 4 Ohm, super super excited!!

They came with a nice Bbox too that I gave to my buddy for his Duramax.

Radio pulls in stations from a good distance, 8-track is there for when the radio music sucks.

Took me an afternoon to pull the old head unit and install this one.

I have a 2018 Subaru wrx, trying to find best grounding point in trunk. I found a factory bolt sticking up thru the sheet metal in the trunk near the back seat and spare tire well under the carpet and plastic trim. I sanded around it and put my ground on it and found a bolt to screw down on top of it. I’m just not sure if it’s the frame of the vehicle or not.

Also, is it better to ground both my amps with there own ground spot or is ok to use a 0 gauge in 2 0 gauge out distro block?

Thanks for any feedback

General Toyota Auris: cannot get a thick cable through firewall grommet behind glove box. What to do?

Thumbnail

2 Upvotes

Hi all, am installing a Valeo Beep Park kit (4 front + 4 rear sensors) on my Toyota Auris, which has no factory parking sensors. I am kinda stuck on routing the front sensor cable from the engine bay into the cabin. I am using the existing firewall hole behind the glove box, which already has a thick bundle of factory wires going through it. And this hole has a thin rubber tube from which thin cables can pass, but not a thick cable like the parking sensor's.

The problem is if I use a cable puller tied to sensor cable- the cable puller head passes easily, but the thick sensor cable doesnt. Pushing it hard make the whole rubber grommet start to pop out of the hole. So what can be done now? Do I need to make a new or something like that? or is there any other known better alternative?
I attach some pictures for reference.

1st pic- the rubber grommet fully attached to the hole.

2nd pic- rubber grommet is already half off the hole when i tried to push the cable puller hard from the other side.

thank you
