Nice video! You did a great job explaining our LC7i, and your detail on setting the gains was well done, too. Thanks for helping other car audio enthusiasts with your videos!

@FarAboveDaCloudz 3 года назад

People look at me crazy when I break out my 'Special RCA Cable' for testing line out voltage. Great video!

@brandonthiergart660 3 года назад

I'm an electronics engineer with a small background in analog amplifiers and a life long passion for music and mobile audio. I've been installing audio equipment and setting gains by ear for 25 years. While that has worked pretty well I was blown away by your simple explanation and I'm humbled. Thank you!

@james66872 2 года назад

I totally agree with you.

@julesbruchez-theartofgrapp9646 Год назад

That’s what I thought also. I checked multiple sources and it’s the same process. Problem I ran across was that the volume to the sub was WAY off!!! I set the highs and Mids with my ear and it’s perfect. Doesn’t matter what I do the sun is just low. I simply went back to the old school ear method and the sun came alive

@maniacalmonster2293 7 месяцев назад

If you set anything by ear it's off.

@mattburgess2 7 месяцев назад

Setting the gains like in this video is fine as long as you leave the eq flat and tone levels at minimum. If you set your gains with everything flat and as soon as you start making eq adjustments or bass adjustments now you'll be clipping. Ask me how I know.

@maniacalmonster2293 7 месяцев назад

@@mattburgess2 you just contradicted yourself. the second half of your statement is correct, as to why you want to set EQ before gain. Everything is set before gain.

@JohnKut 3 года назад

most helpful video I have ever seen about LOCs and bass amplifiers combined.

@JohnKut 3 года назад

one question just to make sure: Amplified voltage at a bass frequency, is the square root calculation made by using RMS or max voltage of the sub? you said in the video "max rms".

@HugeGamma 3 года назад

I agree

@surviver5738 3 года назад

Agreed. I have been trying to understand how this all works and I feel more RU-vid creators are more concerned with keeping their secrets a secret or showing off their shop tools that do not make sense for me to buy as a hobbyist. This video was the absolute best quality and most understandable presentation I have seen yet.

My set up has a lot of crossovers, which makes it more complex to set up gains and tune it this video by this man finally help me great job.Thank you

Your explanations are simple to understand and straight to the point. Thank you for explaining why input voltage from both the Radio AND the LOC matters.

@idscomm 2 года назад

Thank you for the great video! Watching your video and other ones including one by JL Audio made me understand how to properly tune my gain! I actually did that last night, tunes my Kicker CX800.1 paired with my Rockford Fosgate 10" subs. Since my amp provides 600 watts at 2 ohms and my subs are 500 watts also at 2 ohms I had to be aware of the difference. Turned out that with a -5db 50Hz test tone, my amp at full gain showed 31.5v which ended up being almost the max power for the subs! I also turned the Bass Boost off as I originally turned it ON to get more bass... I find I lost a bit of "punch" but like you said, most people recommends NOT using the bass boost on the amp. Thanks for the great video (clean install btw).

@johnstevenson7796 3 года назад

This video ABSOLUTELY answered my question to you on your other video where you apply the LC2i (i.e., asked about the sequence of setting Gains). Main takeaway for me was to assemble the proper equipment and information in order to follow the sequence and perform this procedure correctly. Know/have: 1) a Multimeter 2) Know both your Low Level (i.e., RCA) and High (i.e., speaker high-level) input ranges for your devices in play ... here the LC2i, Alpine amp and other Amp (don't recall the name) so you can apply the multimeter with the test tones 3) Know the RMS for your amps and ohm load so you can apply Ohms Law to calculate Gains 3) Speaker frequency ranges so you can set HPF (if relevant) Thanks and Great Channel

Very nice wire management. Excellent explanation. I have not been using the -5db test and setting up at full volume to see an end result of low RMS output, incorrect tuning. Thanks for the video. Will try this method as it is more real world tuning at listening volume of 75% and the source db levels. Appreciated.
