I want to get a second avatar 15, but the first one (current)I definitely pushed it to see where the critical fail point is at on them, coil is a little scratchy I also figured out my alternator is dying so it’s possible it clipped at one of those drops. How do I go about getting this one swapped and order a second one(building ported box for them)

@CCFIFresno 2 жыл бұрын

A simple thing like that wire splice causes the system a the slightest delay to read it (millionths of a second) but it is a delay and you have it coming on you just don't have the POP to make you aware of it. Hopefully that explains it in lay or non electricianal term's so it's easy to understand for all. My biggest recommendation to any and all is use the connectors people. This is a huge investment to most, it's your vehicle and sound you've paid money big or small but it's yours so ensure you take care of it and you can't go wrong doing it that way.

I'm going to pull stereo and bypass remote wire. Run everything off of the ACC wire (key on wire for stereo, usually red wire). If the key is on everything powers up together instead of going through stereo for ON/OFF operation

If multiple pieces of your equipment/hardware has GTO/remote wire TO technology and you're not using it through the initial source only that is your problem. You also can not splice the wire circuit you use for the remote TO you must either tap into it or use connectors to ensure the vehicles software system reads it as a single circuit on any vehicle with an OBD2 or that has security or other systems run through/with the head unit.

I’m having this problem too. It only happens when we run a preamp. Once we take the preamp out and run everything to the head unit there is no popping when turning the car off or on. Once we add a preamp(asp) popping occurs when we shut the car off. Tried running a relay but still pops. Switched the remote to the ignition and the pop occurred when we start the car and not when we shut the car off. In all circumstances we are running a relay. So I was wondering what should we do? Thank you!

Many times this has to do with your headunit. There is a way to stop it completely, and what he is talking about is to shut off your amps before you turn off your signal source. hiring head units usually don't do this but a lot of the cheap Stereos on the market like those Android head units for $45 do this. this is kind of the reason why engineering does matter and the products that you purchase sure may sound great but it's the little things that really do matter

I've had that popping issue in the past. Turns out it was from my RCAs running next to my live wire and whenever I'd hit the key I'd get that loud pop from the electrical current transferring through the wires insulation and that would cause a break in the signal going from the deck to the amp. I had to completely pull my RCAs and run them on the passenger side separate from the live what runs the drivers side.

Great video thanks JP. I don't have this problem but I've known people who do! Question: say you have a 4 channel amp that you are trying to wire for a car with 4 door speakers and 2 dash tweeters. If I connect 1 tweeter and 1 door speaker to the same channel will they be getting half the watts each? So door speakers is 50watts, tweeter is 50 watts. And a single channel on the amplifier outputs 100watts. If I put the tweeter and speeker both on the same channel will they get 50watt each Or both get 100watt?

@maxwellpickens1734 2 жыл бұрын

You’d want a cross over for the tweeters so it’s not getting the full range of frequency and mess your tweeters up. The wattage is all determined by the ohms on that channel.

@rz9708 2 жыл бұрын

Also when you do put that crossover in it will not drop your ohm load down it will keep it at 4 ohm that's if your door speaker and your tweeter is a 4ohm speaker and tweeter. But definitely recommend a crossover.

@RandoManFPV 2 жыл бұрын

Thank you both for your input. I'm still unsure how many watts my speaker and tweeter will be getting tho. My speaker is rated 50watt rms and my tweeter is also 50watt rms. When I put them both on the same 100watt channel, how many watts will be going to each of them? Will they both get the full 100watts from that channel or will they each get half (50watts) from the channel

You don't need to use a relay, the remote turn on doesn't use enough amperage to require a relay, even if you're using 6 amplifiers. I suggest turning the volume all the way down before you turn your system off. Also use a toggle switch to turn your system/amplifiers on and off with instead of the ignition

I have a Sundown Audio SFB-3000D. Since cold weather (below 45f) when I start my vehicle in the morning the amp fan is very fast and loud for about 2 minutes then it goes silent. It only does this when its cold outside. Anyone have this problem? If it is just a failing fan then no big deal. I can replace it myself. What I'm afraid of is that there is a problem beyond just the fan since it only does this for a couple of minutes then quits and only in the morning when its cold outside. The fan literally sounds like its going to fly apart. The amp is fairly new and bought from D4S. Is running at 2ohm on good electrical.

@Chris2phaBrown 2 жыл бұрын

whining usually comes from having your power and RCA cables too close. The magnetic field around the power wire disrupts the signal in the RCA cable. You should never run RCA and power wires next to each other. If you are running the wires to the back of the car, run the power and RCA cables down opposite sides of the car. A sure fire way to know if this is your problem is when the whining noise frequency increases as the car revs go up (alternator spinning faster).

@your_doctor_and_plumber 2 жыл бұрын

You're a textbook hater. Who cares if he has money and pays others to install his huge complex system? I know I probably would if I had the money. Relays are used to turn things on/off reliably at the same time. I believe some head units send out a pulse of voltage as they power off.. so if your amp is still on when that happens (by not using a relay), the pulse is gonna travel down the RCAs and to the amp. Of course there are other possible reasons for a "pop" sound but that is a common one.
