If so, turn it up to 75%, then adjust the gain on the mids and highs amp to blend with the sub. I like the bass at 75. But I haven’t gotten far enough yet with my doors. They are just “decent” after market doors running off of the amp on my HU. I don’t have a 4 Chanel for them Link to comment Share on other sites More sharing options...

It I set the volume to 28 and have that be my max before clip. Will I be able to turn the gain up on the sub? Or is that not how it works. My thought process is…. If I’m turning the HU volume down almost 10 clicks while turning. I should be able to set the gain higher. Am I wrong? Link to comment Share on other sites More sharing options...
molly4lyfe Posted January 3, 2022 Author Report Share Posted January 3, 2022 Here’s 2 quick pictures to show the completed build. Not factory perfection but I’m very happy with it. Link to comment Share on other sites More sharing options...

Ok, then yes, you should be able to reset the amplifier gain at a different volume to compensate. Just pay attention the the oscilloscope wave. Even at low volumes, you can still clip your subwoofer into failure (which it sounds like you already know). 2011 Chevy Silverado under construction My build log here. Check it out!

I usually see a clip and then turn it down To a clean wave. And then down some more. When I go to 34 or 35 I LOVE the bass. But my door speakers want to cry. I’m thinking about getting a small 4 channel to power the doors but I wanna wait till I do big 3 and alternator upgrade. Link to comment Share on other sites More sharing options...

You probably don't need to wait to get the alternator upgrade to get a 4 channel in there. 4 channel amps (the majority of the time) are a lot more efficient than mono amps playing bass. The big 3 is important though. If you amplify the mids and highs, you'll be able to easily set crossovers for those speakers, that will help protect them from playing too low and playing too high. So that'll help with the harshness of the door speakers as well 2011 Chevy Silverado under construction My build log here. Check it out! Link to comment Share on other sites More sharing options...

Last question I guess is, to wire a 4 channels I need another power wire coming off the battery correct? I don’t want to tap into the existing 4 gauge I have running right?

Yeah, I would either run a new, dedicated 4 awg wire back to the 4 channel, or upgrade the existing 4 awg to 1/0, then get a distribution block, then have 2 4 awg cables coming from that. Either way would be fine. 2011 Chevy Silverado under construction My build log here. Check it out! Link to comment Share on other sites More sharing options...

But I was able to tune the gain but have the HU volume set to 30 instead of 37 so I'm guessing we should be slamming tomorrow. I used the exact same 40htz test tone and the gain went up a pretty decent amount. I was quite surprised to say the least. It was only 7 Degrees when I tuned it and my fingers were shaking. Didn't have the man power to test it out much besides with the truck doors wide open. Ill post an update tomorrow. I wish I did some more documentation of the build but I got super busy and eager to get it in so that just didn't happen. But I'm guessing this thread will close here until I do some Mids. Thanks for the support and tips from my 2 followers lol. Link to comment Share on other sites More sharing options...
