Cheers. Thanks for that. If that's not possible (filters always on), then you'd start with high-pass filters set to their lowest frequency and the low-pass filters set to their highest frequency. Maybe that one speaker wire is picking up noise somewhere in the car? the difference being that the former is the manufacturers recommended limit for "stable" power, and though there may be headroom between that number and the clipping point (your extra found power), it was not necessarily stable there... do you have any insight on that? Fair enough, can you please tell me which oscilloscope you used during your tests? Download this uncompressed low-distortion WAV file for measuring your system distortion level at 1KHz, beginning from the digital source: 1KHz / 0db tone @ 192KHz / 24bit samples - 60 seconds duration (zipped) Below is a sample measurement on Macbook 12" with internal loopback in place with the above WAV file as a sour In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. Since I think the subs will prob Be around 70-80hz LP, the mids 100hz HP and the tweeters 1.5k HP. Buck, I have an LC7i in my system taking the stock headunit speaker level outputs to line levels.

Nathan, It is my understanding that if you use the Auto Setup process for your Key 180.4, you leave the amp gain at minimum and the program automatically sets gain, balance, fade, time-alignment, high-pass filters, and EQ optimized for the front seat position or wherever you put the Setup mic. Pete, That sounds right to me. That translated to about 77 watts. I have read some tutorials stating that you should only use the scope and test tone to set the gain up to the voltage calculated by the units actual power and the 4 ohms, and not the clipping point. Does this mean I leave my amp gain at the lowest setting (4V)? (not test tones) in a car audio system. When you're determining your HU's max clean volume, your gains at that point are at the minimum, right? My JBL 2402 tweeters was replaced with new Diaphragms I am Try amping with a all tube Lucman 3 Way Active Crossover and use a 211 Power out Valve amp for my tweeters 16 Watts class a per channel my tweeters volume is very low even with my years very close to it how can I improve the gain onu tweeters. Thanks, I do not recommend that way of setting gain because it doesn't take into account whether or not the source is clipping, nor the accuracy of the meter at any frequency besides 60 Hz. Our customers were recording studios, nightclubs, and touring bands. Natasha, That's impossible to tell without at least knowing what kind of vehicle you have. Different meters will have different degrees of deviation. I have installed a Pyle 5 channel amp 6800 watts into a chevy cruze.. Powering an alpine 12" sub rated for 1000 rms. Do I put filters on the amps before tuning with the 100hz or after? I really appreciate the clear response (perhaps dumbed-down for me, thank goodness) and the informative article. Next, you turn up the amp's gain until you hear the distortion again, then back it off slightly, and you're done. Thank you to all our front liners who have requested face shields. A sine wave sounds like a hum.

How can you get 17.2V RMS on 13.5 DC power supply? Using a standard hand-held multimeter to measure the voltage of a higher-frequency signal results in readings that are much lower and leads to inaccurate power calculations. John, No. I turned up the gain on the amp and it never went past 10V. I've tried setting by ear but the E60 BMW does not have a visual for the volume so it's difficult to tell when one has hit 3/4 volume etc etc plus the buttons can be pressed til time immemorial without one having the foggiest whether you've hit the top, mid-top, somewhere-top, not-so-top etc. Oh and I have the two 12inch MTX Terminator subs in a box whats a good amp?

Okay so I've been running 2 Infinity Kappa 100.9 W's in a sealed box with passive radiators tune to 27 Hertz and it sounds phenomenal at 600 RMS each even though they're rated for like 375. I noticed you talk about setting the gain at minimum while figuring out the HU clipping volumes but where would the amp's crossover be set during three processes? If I had wanted to, I could have set the amp’s output to exactly 50 watts, by turning the gain down until the voltage read a targeted number, in this case 14.14 volts AC. Is it at 0db or -10db? Kevin, You should set your receiver's EQ and the amp's bass boost to the way you normally listen to your music, before finding maximum clean volume and setting amp gain. With the pioneer I can get 25v from the amp easy, with the JVC it can barely reach 6v, tried a new JVC 2-din with same preout voltage, same result barely 6v output. even without the oscilloscope, the tones made it possible for me accurately set the gain. i can set the rear gains to about half way on their rotation.

SpeakerCompare simulates the sound of home and car speakers through your headphones. And also should the subwoofer be turned off when finding out the max clean volume level that your head unit clips at? Logically it seems appropriate since theres lots of activity going on in that frequency range, normally played at higher levels than 35% HU volume. Most manufacturers recommend playing familiar music with the amp gain low, raising the receiver's volume until the music distorts, then backing it off until the music sounds clean again. By using test tones played through a speaker, I wondered how accurately I could set an amp’s gain as compared to setting it by the other methods. So basically to tune properly the LPF needs to be all the way up along with the volume at the proper level then adjust the gain till it clips/distorts/buzzes right? Surely these speakers should be able to take about 35% of HU volume with no eq boosts and the amp gains turned down. At first, I played a favorite R&B-type song full of percussion, bass, horns, and lots of production — but I couldn’t hear it distort, only get loud. CONSULT A TECHNICIAN. And if I use a oscilloscope to test tone the crossovers should I test the amps along with it first so the amps are at their full potentional before the crossovers?

After turning the receiver down a little, restoring the fine quality of the singer’s voice, I turned up the amp gain until I heard the same thing. Especially for those who leave comments on multiple articles I wrote. Thank you! Two subwoofers that can get wired together to form a 4-ohm load cannot be rewired to form a 2-ohm load - that's impossible. What gives??
