  1. I surrender, setting gains. DD-1

    RF HLC and HLC-4 will likely give you the same problems. The RF BLD should work well for you though.

    Here is the problem, the inexpensive LOCs use a transformer to take the high level signal and reduce it down to low level. Transformers work by creating a magnetic field and transmitting the signal that way. Like wireless communication. As you may be aware wireless transmission works best at high frequencies, at lower frequencies it basically stops working. That is what is wrong with all the inexpensive LOCs out there, they use transformers. It works fine at 1kHz, but below 50Hz the wheels start to fall off. At 40Hz they are so distorted the DD-1 will report distortion at any level. By 20Hz there is nothing that resembles a sine wave coming out of those things. The transformer coupled LOC is a great example of a product designed by a marketing person. No electrical engineer would ever recommend that.

    Tony this information is very informative. Thank you. I just recently purchased a dd1 and i have temp set up in my vehicle and have a pos HLC in it and i experienced the problem you explained, with perpetual distortion at any level at 40hz. This question might be against forum rules as the answer might be construed as bashing, but do know if Audiocontrol uses these "transformers" specifically the LC2i? I could be foolish in assuming it would not since its a powered device, but im no expert. Thanks

  2. Stock alt, high voltage

    in XS Power Batteries / Chargers! (and other stuff too)

    You're fine. Let it run for about 15 minutes

    Thanks bud, granted i havent checked it again since(approx 1pm). Left the meter at work so do know if its changed or not.

    the charging voltage will change depending on the temp of the alt. a cold alt will charge at a higher voltage than a warm alt. so if in your picture the truck hadnt been running and had enough time to cool down, then it is a cold alt. after running for a few minutes the charging voltage should drop a little bit.

    Was not aware that was a thing, but I do now. Thanks for the knowledge

  15. Which brand shall i get

    in Subwoofers / Enclosures

    ive been planning my next system for awhile now and its getting to that point in which i need to start making the final decision's...im doing 2 18's.on 2 AQ2200.1's ...im either gunna do [(2 18" DC lvl 4XL's)] or [( 2 18" FI BTL's fully loaded)] im not really building the system specificly for numbers but that doesnt mean i wont compete ,but im looking more in the massive flex, massive air movement and ofcourse the HAIRTRICKS...i plan on having wicked lows and it will be tuned to about 30hz ....so all im asking is which subs will fit my need the best..
