Just a note about capistor selection when you fixed the issue, they used a ploymer cap there for a good reason, even through the delay was copy and pasted from a better uint. I'd replace it again with another polymer SMD cap as their ESR is more stable over their lifespan and they don't develop leakage current as easily. The typical Electrolytic Polar Capaster that you installed works really well now but will wear down over time. This is just nitpicking. There are much bigger issues with this amplifier than the specific capacitor that you picked. Like the complete lack of transformer goop. and the lack of board support. And just generally... Did they think about this and or test this at all? Keep up the awesome work in the awesome videos. They've been informative and very handy. I've been doing a lot of car amplifier repairs lately.

This amplifier uses the same circuitry for its delay and muting that I do in my DIY amps. Its sensitive to the DC input voltage as a fixed reference is being used to determine when the relay pulls in (usually a zener) and a fixed RC value. This means that the time it takes to charge changes with input voltage. Additionally, this can potentially cause issues with the relays as the switching time becomes more protracted as the capacitance is increased or the voltage is reduced, leading to a lazy pull-in and potential chatter and arcing. The design works much better when the voltage references for the turn-on thresholds are kept well away from the incoming rail voltage so that the charge waveform is a ramp and not an exponent, usually just using the transistor junctions themselves or a small signal diode if its a fet. Edit: They may have it set up like that to act as a really lazy under-voltage lockout circuit. Voltage too low, relays wont pull in.

I knew Robert personally. He would not let a "little" audio issue leave the factory. John or one of the other techs would have caught the issue before the amp was boxed. As for the board flex. Where talking about a man that has a 2 ton granite boulder on the side of the production line, he uses to see if his product distorts when heated to operating temperature......product is just ran on top the granite for a day. Measurements are taken to see how much the heatsink, and bottom plates expand and contract. If a man is going to put a amplifier into 3 separate enclosures ( aka Zapco 3 piece amps ) so as to get the best sound. He is not going to have "little" defects leave his shop. As a person that's used/sold/modified Zapco products for over 45 years this is how Zapco used to be: "Hello Zapco. Could I get my product re-silk-screened I painted the amps the colour of the car?" "No problem." "Hello Zapco. Could you put two of your PX equalizers on 1 face plate?" "No problem". They had a flat rate repair charge....never over $65.00. Only product I had to send in for repairs. Was customer damaged PEQ's.

What is causing this problem? RCa input is clean. After my test with third amplifier, for a moment i got better sine wave in second amplifier, The problem: Amp blowing speaker much before distortion output, bass is weak / weird, flexing car but i dont hear and fell presure, Wave sine on out amp is rippling like Phase reverse - back normal - reverse - back normal itp. In warm temperature sound (bass) can be much better for a few minutes only. Or sometimes multipe disconect power wires can help back clear sine wave Which issue fits this problem? Input noise, Resistor noise, Thermal drift. And how to solve this problem. Thanks!

Another somewhat nasty thing about these older designs is pretty much no real protection for the switching transistors since they are based on older PWM chips. Sure it will "shut down" but only after its managed to nuke everything downstream. One of the nice features of newer SMPS/amplifier technology is the ability to switch faster and do cycle-by-cycle monitoring to detect faults which allows shutdowns in a matter of a few hundred nanoseconds. This means if something goes wrong it wont blow every single damn transistor that was on at the time of the fault. Car audio stuff really is in dire need of a design overhaul. It would not only make it more reliable, but also potentially cheaper as the designs could be more modular.

It’s 2024 lads! The amp reviewed as per the serial number visible is 2017 (first four digits is the year of manufacture). This model was out in 2014. I’ve used it then and it was a good amp for its time and I personally got very decent support from Zapco. I think it’s not fair to compare it with current offerings and seems rather biased. Old stock capacitors will depreciate over time causing the pops. That’s a known fact. And humidity (especially for us in the tropics, it’s a pain) does not help the board glue, etc. The model reviewed was a good product for its time. We need to move on to more current offerings.

This flaw is a byproduct of "lego" engineering. You have two separate sections, or modules, of the amplifier that are not properly integrated and thus fail to work properly as a system. The use of delay timers and such is a reflection of just how old and simplistic this design is. The correct approach (and what many modern, high quality amplifiers do) is to have an MCU control the relays and the MCU doesn't engage them until all subsystems have reached a nominal state.

Similar prices, what do you think about the Rockford Fosgate 2500.1 bdcp?
@JasonWW20004 ай бұрын
Anyone can tell you, it's definitely a quality amplifier that will probably do closer to 3,000 watts. I'm curious what Sam is going to say about them.

Yeah the Rockford is absolutely lightyears ahead. A proper bespoke designed amplifier using great technology. However, it's still a stupid amount of money to pay for 3krms when you can just get a Smart 3 Bass which is also superb 😂

Anyone know where to get the power and ground connectors they use for amps like these? The pcb mount 1/0 terminals?

Hey man i am about to run 8-4500's a guy told me I can run the dd zvl and set all amps to slave could u do something to demonstrate this I do not understand this
@JasonWW20004 ай бұрын
Are you using a different brand of amplifier than DD? If so, it looks like you can run up to 10 mono blocks from a single dvl. You would turn down the subsonic and turn up the crossovers on all of your amplifiers. The dvl would then perform both of those functions as well as let you use a single remote Bass knob. The one step you'll need to do is calibrate the gain knob on each of your amplifiers to a set voltage so they are all identical.

Why anyone wouldn't run class D in 2024 is beyond me. You almost deserve it. Zapco knows what's up. They're getting it while they still can.

How simple it would be if there was just only ONE amplifier brand with only 10 models available. But the audio world is a huge clusterfuck!
@JasonWW20004 ай бұрын
No, just the opposite. It's good to have a lot of different brands competing with each other. That's what keeps prices low. Imagine there was only one brand, they could charge whatever price they felt like charging and you couldn't do anything about it. Car audio today is the best it's ever been.

@@JasonWW2000Curious: What brands are properly priced these days and not just the same Korean/Chinese crap that people pay $60 an amp for and then sell for 10-20x for?

@@orangejjayIt's all personal preference. The amplifiers that I run are Rockford, Kicker, Arc Audio, Focal, Digital Designs and Alpine. I can definitely recommend these brands. If your wanting extremely low cost amps your gonna have to look at a clone design. A few of the better brands off the top of my head are Stinger, Recoil, Skar and the JP D4S amps. I don't know what your budget is, but buying an amp second hand is a great way to save money.
