I'm wanting to upgrade to 2 twelve inch watt speakers. From what I've read this will allow me to turn down my gain and still have it sounding like I want without the clipping any suggestions and do you think this will work?
I don't hear it clipping like what I've seen in the videos but I try not to push it because cant afford the speakers for a couple weeks. Our subwoofer shopping guide will help you determine which kind of subwoofer and bass system you need, to get the sound you want.
Here we discuss the most popular fixes for an underpowered electrical system: the big 3 upgrade, a capacitor, a high output alternator, and a second battery. What does the gain control do anyway? This article describes how to adjust your amplifier so that your subwoofer sounds just the way you want it to. This step-by-step guide will help you make sure that your amps and subs are evenly matched and work well together.
We explain how to select one to go with the other. Which subwoofer will sound the loudest? Or the deepest? Which hits harder: one 12" sub or two 10" subs? How much power do I need?
These answers and more in our FAQ. Dual voice coil subwoofers are a popular choice among car audio enthusiasts who want more flexibility in wiring their sound systems. There are many ways to connect subwoofers to an amplifier. Our wiring diagrams will help you find the best way to wire your subs and amps so you'll get the best performance out of your gear.

Just adjust your head unit until you hear distortion, then back it off just a bit, then do the same on the sub amp. It's not gonna do a whole lot, cause, well it's a entry level amp, and sub that's more for just filling in the low's, then moving a lot of air. If you feel you need more bass, just use the amp on your highs and mids only, and buy a dedicated mono amp for your subs so you can feed them some clean power.
And if all that ain't enough, just upgrade subs if you have the funds of course. And if you wanna know if a amp or sub is hot, just touch it. You can feel the dust cover on a sub, and tell if it's getting too hot. I don't know where you heard clipping doesn't kill subs but that's exactly what kills them. The signal is turned into heat and all that heat will burn your coils. But to much power can also kill them by overdriving them into mechanical failure.
So, would i just be able to hookup a D mono amplifer just for my subwoofer? So since my 4 channel amp is RMS per channel. But if i disconnect the subwoofer from it, its only RMS. M5 or someone else who knows this very well, i just read this from another place on internet. It's 1. Basically if thats true My subwoofer is also rated at RMS. Just setting the gain at some arbitrary number is the wrong way to go about doing it if you are trying to reset.
The gain is used to match the amp to the signal it is seeing from the source head unit, processor, phone, tablet, etc. Think of it like a garden hose with on of those adjustable squeeze handle nozzles on the end. The spigot the hose is connected to is the source and the nozzle is the amp.
You turn on the spigot and go to squeeze the handle and just get a mist gain is too low. You then adjust the nozzle until you get that perfect pressure stream you are looking for correct gain setting. Have you ever opened that nozzle all the way?
It's a very rough and general analogy, but hopefully it helps. Yes, that is a very real possibility. It can kill both amp and sub. It also depends on the music you are listening to. If it is a constant heavy bass line then things will heat up quickly. If it is maybe a song with a kick drum being the only real bass signal then it probably wont cause much harm, thermally that is.
It doesn't matter what the signal looks like, whether its a perfect sine wave or a square wave, if the power received over a period of time exceeds the thermal capability of the woofer then it dies. Setting gain on the amp will always result in some level of distortion unless you're super conservative which you should never be.
If the amp is distorting due to clipping you can easily hear it. If the sub is reaching thermal or mechanical limit, you can easily hear or smell that as well. No need to get out the calculators here. That starts by watching out for pop and sizzle sounds. These are trademarks when a subwoofer is not getting enough power. As a result, the music output will not have the detailing it should have for the equipment at hand. The problem is that when this happens, the amplifier goes above and beyond its job description to fix it.
The clipped output signal then puts strain on the subwoofer to over-perform. Now, subs are not meant to extend these services which causes them to overheat or burn out and eventually get torn.
Subwoofer popping is usually an indication of the fact that the cone inside the subwoofer is moving too much. Each of these oscillations makes sure the cone gets pushed and pulled just the right amount to make sure that the sound waves get enhanced the way they were designed to.
When the cone moves a bit too much or too quickly, it makes a pop sound. It means that the signal inside the cone is trying to move at an infinite speed which is not possible. When it does that, the sub gets overheated and might tear itself. Either way, you will end up with a damaged sub.
You might also hear a thumping sound that happens when you change the input parameters on the audio video receiver or AVR which sends the signal to the sub to be reproduced. When you change the receiver settings, the sub just replicates the same. Speaking of pop sounds, sometimes the receiver mutes all the jacks briefly when it loses its input audio signal. Just make sure you get it serviced to contain the problem. In the meantime, you can adjust the bass levels in the receiver to match the gain levels on the subwoofer to reduce the pop sound a little.
Doing that is actually quite simple. Look at each input device and note down the settings. The problem with this setting is that it takes longer for the receiver to detect the input audio signal. In the meantime, the jack gets muted and you hear a thump from the sub. As mentioned before, prevention is a lot easier than cure in these situations. The best way to make sure that none of these mishaps happen is to take care of the signal levels of each of the components of your audio equipment.
The first detail to check is the RMS rating. This is the best way to decide its capacity and check what else needs to be adjusted.
