Ambassador of Bass Posted August 27, 2012 Report Share Posted August 27, 2012 I just installed my new system and it is REALLY not working right. Ok I have stock battery (Napa the legend 75) under the hood with a Denso 200amp alt. (was there when i bought the truck), big 3 1/0 guage under the hood, Kinetik hc1200 back by amp, Crossfire XP1400d, Fi Q12 dual 2 wired @1 ohm, 1/0 power lead between batteries and 200amp fuses next to each battery, 1/0 ground to the frame from both batts, 4awg wire from Kinetik to Crossfire amp with a 100amp fuse (wires are under 2ft. each), pioneer premier headunit. The problem: I have tried 2 amps out both rated to do 1,400 rms at 1 ohm and when i try to get the gain adjusted i just get clipping. I have a oscilloscope and a dmm. I am getting a clean signal from the rca's coming in (according to oscilloscope) and i have a solid 13.9 volts at the amp and under load it NEVER goes below 13.6...i have tried two GOOD amps and i get clipping WHY??? I put headunit 75% up, eq to flat, 50hz test tone (downloaded from youtube), and turn it up till i get the 1,400watts...even with the speaker unhooked the amp clips! I thought maybe i had a bad ground so i moved the amps ground directly to the Kinetik and moved the Kinetik's ground to the frame...cleaned metal nice and used the right hardware...it's strange both good amps clip at pretty much any headunit volume and/or gain...i have set-up many systems so i know how to do it but this has everybody around here stumped...what's wrong?????????? I thought i had a bad amp so i got this new crossfire amp and same thing...just clipping...ughhhh please help i am having NO luck! Thanks in advance...one CONFUSED basshead.

CDetty Posted August 27, 2012 Report Share Posted August 27, 2012 Could the test tone itself be clipped? 1999 Honda Civic- RIP 2003 Acura RSX Type-S Link to comment Share on other sites More sharing options...

Jessica Posted August 27, 2012 Report Share Posted August 27, 2012 Let me ask this, do you have a clamp meter? You need to know the amperage and wattage. You might be trying to get 1400 watts @ 3ohms with box rise from an amp rated at 1400 @ 1ohm.And also download the tones from here http://damoreengineering.com/dd1.html at the bottom of the page are the dd-1 test tones. Clean and unclipped at various db levels. and that Tony for using his bandwidth lol Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

MrSkippyJ Posted August 27, 2012 Report Share Posted August 27, 2012 Test tone from YouTube. That is the problem.

I added another ground (had extra wire), got a higher quality RCA (JL audio blue-series) and used a GOOD test tone this time and it works!!! So in summary it was the tone...thanks!!!!!!!!! I lost the good tone i had and had to download that one last minute...turns out when you rush something you get a headache lol Audi A6 Quattro Wangin' Wagon Pioneer Premier DEH-P5901B Headunit w/ IPOD control American Bass SQ5.25 in the Doors Compression Drivers and Horns under Dash 2 American Bass SQ475's for Mids/Highs4 American Bass HD 15's American Bass 500.1 17cuft 3/4" Double Baffle Birch Enclosure 240sqin port @38hz1/0 AWG Stinger big 3 under hood4 Runs of 1/0 AWG Stinger Power and Grounds Stinger Fuseblocks(3) XS Power D3100 Powercells120 amp AlternatorBlue Streetglow Underglow and Interior with Music InterfaceEscort Passport 8500 X50 HardwiredScanGuage II with voltage Readout Link to comment Share on other sites More sharing options...
