bobonit Posted February 28, 2011 Report Share Posted February 28, 2011 My cd player put out 6V so ur saying my gain should be 0? Cause my amp getting 6V threw my RCA my headunit has gains built in for every rca output, not just sub, i dunno how the new alpine stuff works but mines an oldschool pioneer deck with digital xover kinda like a 360 or imprint type deal sorry if u miss understood Naw ur ok. I have a alpine imprint too with my alpine cda-105 so my amp get 6V threw RCA. I was going to turn my gain up to bout 45% up with my subsonic at 30hz or 28 hz. Alpine Imprint only has 4v preouts, just saying. You are not getting 6v out of it.

General Posted February 28, 2011 Report Share Posted February 28, 2011 Forget the pre-out Voltage... I've just one easy question: Why do you think they tuned your amplifier wrong?

Alpine Imprint only has 4v preouts, just saying. You are not getting 6v out of it. My alpine hu put out 2V so total of 6V. It doesn't work that way. Couple of questions for you. 1. The 2v Preouts are referring to the RCA connections, not the AiNET connection. Are you connecting the Imprint to the RCA's on your headunit for some reason or are you using the AiNET connection? 2. Even if you were connecting to the 2V preouts, you don't just add up the voltages. Whatever the preout voltage on your processor is, thats what it is. It doesn't just add together as if they were batteries in series. Its the same as an amplifier. With your logic, your amp will put out more power if it has a higher input signal which is not true. You have 4v Preouts, not 6v. Quote 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...
CJ18 Posted February 28, 2011 Report Share Posted February 28, 2011 Do you know how to test to see what you RCA voltage actually is? Quote Link to comment Share on other sites More sharing options...

And I was gonna buy a 4V line driver but he said the imprint would be way better and u get more eq on ur hu..thanks man ur helping alot.

Brenton1 Posted February 28, 2011 Author Report Share Posted February 28, 2011 Do you know how to test to see what you RCA voltage actually is? How? I have a dmm. Put it on 200V on my dmm? Quote Link to comment Share on other sites More sharing options...
bobonit Posted February 28, 2011 Report Share Posted February 28, 2011 Do you know how to test to see what you RCA voltage actually is? How? I have a dmm. Put it on 200V on my dmm? Depending on your DMM, you want to choose AC Voltage. If it is autoranging, that is all you need. If it is not, choose a setting that is close to but higher than 4v. Put the positive probe on the inside RCA connector and the negative on either ground or the outside connector. Turn the volume up and you should see how high the voltage goes. Now to see clipping, you should really find someone that has an Oscope. Maybe there is an SMD member with one that is near you?

Tell u the results and I'm put my sub level at 0 the shop had it at +15. I'm be safe and tune my amp like my buddy Andrew Bailey said he good about audio. I'm buy one. Were can I find one and what kind I need? What price I'm looking at? Thinks. Quote Link to comment Share on other sites More sharing options...
