Right or wrong until this point i have always tuned amps by ear and have have really good luck getting things to sound good. After tons of research and watching various videos on YouTube, i know that I can get more out of my systems. Question 1. When setting amps with the dd1 and other special tools, I see how to tune the amp to the max for the gain. I don't know how that would set that for a particular speaker. For example a 6.5 vs a 8in mid range. Obviously they are going to have different capabilities. Also the difference between various types of speaker frequency. 2. When using a crossover, i know you tune frome the source down the line. How do you know where to put all the crossovers before the amp? 3. When using a crossover before a amp, do you just set the amp as flat with no filters? 4. How do you tune the amp to run certain frequencies as recommended by the the speaker and how the max rms power it can handle?

Currently I am setting my gains on my d-4.800 and I am noticing something I have never seen before. First I use the dd1 on my head unit and I get max hu value of 39 of 40 When I go to the dsp on the d-4.800 I leave the input at 0db. If I go over this the max input light on the d-4.800 lights up. When I try to set the output gains at HU volume of 39 using the 1khz -5db it allows me to set the gain all the way up with no distortion. I think I am doing something wrong. I have used the dd1 before with my 360 and never had this issue. Any advice would be greatly appreciated. Thanks Bret

How should I tune my amp and LC2i using the DD-1? I'm lost on how to tune my LC2i properly, how should i set my Acubass and bass settings along with my bass knob ? AMP-SKAR Rp4500 (Input sensitivity 6V~0.2V) 2 Sundowns U12 D4 wired at 1ohm BOX build to specs at 32,

Being new to car audio, i don't understand what "gain overlap" really means, -10db, -5db, 0db ? What is the best way to tune my system with my DD-1? And what settings should i set all my dials in the amp? This is my first time using this and I don't want to misunderstand steps from the manual. 2sundowns U12 D4 wired at 1ohm Skar rp4500 amp LC2I ACR1 (bass knob) for LC2I

hello I recently purchased a distortion detector and the problem is I have a BMW 3 series and it does not show the volume level, How would I use this properly without knowing the acutally volume level that its at?, it's the navigation headunit type, Plus if I remove the subwoofer speaker wire from the amp, the door speakers still play loud from the Cd tracks is that normal ? becuase in YouTube videos i see online i dont hear any sound while they set their gains. 2 Amps: Mrv500, do I set the LP filter back to 80hrz after its tuned? 2 subwoofers: Pioneer TS-W309D4 12" Champion Series Subwoofer with Dual 4 Voice Coil

I just bought a dd1 distortion detector and I was wondering what track I should play to tune my amp. They have -5db, -10db, and -15db. I currently use a usb with all songs downloaded at -7.5db and want the loudest and cleanest sound I can get out of it. I have 4 skar ddx 15s on a crescendo 4.5k @ 1 ohm. And will using a dd1 make my system much louder if tuned right?

I am currently using only a SoundQubed 120.4 amplifier, with a set of components on the front channels, and a set of subs bridged on the rear channels. If I set both front and rear channels with the DD1 4 channel instructions, I get significantly less output through the subs. If I set the rear channel (bridged) with the DD1 sub amp instructions, the subwoofer output increases. My question is, is it OK to set the bridged rear channels of a 4 channel with the sub tracks, if that's what I'm using the rear channels for, or should I stick to the 4 channel settings regardless? I haven't seen anyone ask about this yet.

Hello everyone im new to the forums just made an account today but I've always looked for info on here just finally made an account. I recently ordered my dd1 recently and finally got it home today. Ive always had friends tune my amps in the past but this time I wanted to give it a try myself. My amps are autotek sm4 1000.4 and autotek MM2500.1 if yall needed to know. When I go and set my gains up on the amps im not sure what to turn up and down. I have went through all the topics and couldn't really understand much so that's why im asking. 4 multi amp it says put in full and db at 0 but for the LPF and HPF do I just crank both all the way or leave it alone? Because it says turn frequency all the way up. Im new to tuning so I am unsure on what to turn up or down on HPF and LPF. Mono 0db subsonic, level, bass nob, and LPF so do I put the bass nob all the way up and crank the subsonic and LPF all the way before I do the ggains? Im not too sure on subsonic and LPF If yall can help guide me through this that would be wonderful and any information is appreciated thankyou everyone!

Is the SMD DD-1 worth the money? I just blew a sub and want to try to prevent this from happening again, and just want better sounds.(mids, highs, ect) Thanks

anyone in oc have a DD-1 they could let me use/help me set my gains? ill drive to you and bring you some beers

okay i just bought the dd1 a few days ago and i had couple quick questions. When tunning the amp should i use cd test track or downloaded versions on phone via bluetooth. honestly i dont listen to cds im either pluged into aux usb or bluetooth does that mean i should tune my amps while playing the track on my phone using aux usb or bluetooth or does it not matter its all them same??? reason i ask is because aux usb and bluetooth are considerably louder than cd i have pioneer 4800 bhs

i put in an audio control lc2 to use my stock radio on my 2017 silverado. my issue is that the dd1 shows distortion before signal detect on 1khz and i can turn it all the way up and it never detects 1khz. Im tapping into my dash speakers for signal since thats where the chimes and bluetooth calls are heard from that way everything still works like stock. i dont have my cd that came with the dd1 im using what i could find on google and youtube either one does the same thing.

Hey Guys, I sent in my DD1 for repair I believe right around the first week in January 2019.. I got a message back from D'Amore Engineering on January 28th stating that it needed some minor repairs and to go ahead and pay for an "Overhaul" and that would cover it. When I went to pay for the "Overhaul" the only payment option was paypal... PayPal closed my account on me because of too many personal transactions. They said I was too high risk for them..lol whatever that means.. So I cant use or open up another paypal account. I replied to the [email protected] email that contacted me about the repair on January 29. I explained that I could not use paypal for payments and asked if there was any other way I could arrange payment for the repair... I have not received any response and have since emailed them again and again. This is in no way a bash post on D'Amore Engineering.. I was just wondering if anyone else has had this issue and if there's any way that I can get a hold of someone over there at D'Amore... I love their products and have sent stuff in for repair in the past and never had an issue... Any help would be greatly appreciated. Thanks, James.
