      I thought those amps already had a dsp in the amp itself, or am I missing something?

      It looks like you go go from 1/0 to 4 guage wire. What do you use to step down the wiring for the DSP? Knu concepts doesn't sell a 16 gauge distribution block.

      Your knowledge is amazing! They say on the internet you should not ground at the same point? But I would do it the same way you did in this video with a distribution block. Where or how did you learn all of this knowledge? Lol - Keep up the great work!!!! ❤👍

      do you not have to crimp the ferrules ?

      No the heat shrink holds the ferrules in place and it becomes crimped once you tighten down the set screw

      The epicenter... Is that important, what is it? I was going to get the 1,500 watt Audiocontrol amp for my sub, the 1,200 watt 6 channel for my front and rear components and was thinking that would do... ???? I have an aftermarket head unit.

      why didn't you strip the grounding point for the ground? I lost an amp and lost power in others for the same thing. I now strip and drill through the body for a better ground and longer life for my amps(all 3).

      I need some advice... I just installed a 12” kicker comp C and a fosgate prime amp on 4 ga kit. It sounds really good when the car is off but when the car is running the sub sounds blown. I never encountered that before and I need help. Any advice will be much appreciated. Thank you

      You are getting engine noise. Try running the power wire down one side of the car and the rca cables down the other side separating them. Also make sure you have high quality insulated rca cables. And one more very likely cause is the ground. Make sure you have the ground wire mounted to the most solid piece of steel you can a direct frame connection is best also make sure you have a nice sanded smooth spot where the ground is mounted to the frame.

      Is It safe to run (1) 4 gauge in & (2) 4 gauge out from a distribution block or should i only go 0 gauge in to multiple 4 gauge out?.... running a 4ch amp and sub amp on 2 12in CVRs

    • James F
      James F In reply to G Vision Films

      Is it safe ?? Yes it's safe! Now depending on how powerful the amps are will depend on whether you will suffer a voltage drop or not. If your running a couple of 300-400 watt amps ehhh probably won't suffer too much drop. If the amps are any bigger it's a very good chance of significant drop and I would suggest at least a 2 awg into the district block.

      The rear deck on my 2014 Honda accord has a lot of rattling near the speakers and third but nothing has worked so far. Can you make video on how to sound deaden the rear deck of a sedan car with a third light.

      Good evening. I was wondering if you could give me some advice about the first investment in the car audio about the tool that I'm undecided to buy.
      I'm not sure if buy first a jigsaw or a router? I'm thinking the most multi-task for me to star some small project.
      Thank you.

      Hey man, quick question hope you could help out. Would you happen to know why my new rear car speakers that I installed wouldn't power up even though the front oem ones produced sound fine?

      about 6 months ago
    • James F
      James F In reply to So envious

      First off did the rear speakers work at all before you changed them or is that the reason you changed them. If the old ones didn't work then you might have a broken connection somewhere. If he old ones did work I'd recheck your connections where you added the new speakers maybe even try and see if any other speaker will work hooked up to those wires. It's also possible you got a bad new set of speakers or very unlikely idea if you got an extremely high dollar very powerful set of speakers the head unit might not be powerful enough to run them. Just a few options to maybe try.

      You may have addresses this in a previous video i missed but I am curious how you deal with running speakers of different RMS rating off same amp...for example I want to run an indash pair of mids that RMS at 30 watts per channel but my full range fronts are 60watts rms and read doors ar 50watts RMS. I want to make sure i get the most power available without damaging the smaller in dash speakers.

    • James F
      James F In reply to TheJedidragon529

      If it were me most stereos will easily power the 30 watt speakers so I would run them from the head unit and then a two channel amp to the other two sets.

    • James F
      James F In reply to TheJedidragon529

      To do it properly you will need a six channel amp and it should have gain controls for each channel. That or be running some crossovers and switches that will be a bit more complicated to dial in.

      Hopefully he gets into making those runs pretty. There’s SOOOO much wiring porn that could happen here.

      Definitely a lot of potential happening.

      Is it necessary to fuse the smaller wire when you go from a thicker gauge wire to a thinner one as you have in your distribution blocks?

      about 6 months ago
    • CarAudioFabrication
      CarAudioFabrication In reply to Joe Nguyen

      Yes, anytime you step down wire size the largest safe fuse you can use reduces so you should have a fuse in the transition.

      Could you do a video on any helpful tools to mount your subwoofer enclosure to the vehicle floor? I haven’t seen an in depth guide on what methods to use best or what methods to avoid using. I have a hatchback and don’t want my box to go flying in the car of a collision.

      Did you say tinned ofc? Wouldn't that be cca?

      No. CCA is aluminum with a copper coating. (Copper clad aluminum) The tinned OFC is pure copper with a layer of protection to prevent oxidation. Great for marine and automotive environments.

      Love all your videos. After following your work I finally got myself a subwoofer system for my car. I have a 2015 Infiniti Q50s. I recently bought a pre built subwoofer box with 2 12" Alpine Type R subs installed in the box, a 1700 Brutus Hifonics amp with a LOC. I hooked everything up to the factory system and it sounds great and all but I find that it's not as loud as I thought it would be. Would love to hear your thoughts and advice on what I should do. Thanks in advance

      Hello, I am loving your videos. I’ve recently bought a car which came with a old sub Pioneer Ts-WX75A and it was wired behind the radio, with the constant wire giving it constant power and acc for the other power, now bought a Pioneer Deh-s510bt and it has recently been acting weirdly losing memory, Bluetooth devices, audio settings. So I tried disconnecting the subwoofer and it starting working correctly, how should I wire that subwoofer ? I know nothing about sound...
      Checked the constant power and acc, to see if they are wired correctly to the radio and it is right. Don’t know what to do can you guys help me ?

      Sometimes you need to swap the red butt with the yellow one (of the stereo).

      Can anyone tell me how to figure out the optimum size speaker enclosure for a given airspace like how big to make a box for the size of the internal size of my car air space wise? I cant find a good answer for this question anywhere
