dagodpere Posted December 27, 2011 Report Share Posted December 27, 2011 (MY SETUP IS BELOW) So I started the distortion test on my head unit and found that one of my RCA outputs was bad so I had to replace the Line Output Converter. After replacing the LOC I found that my head unit clips at 26/32. Then I went to set my bass amp, set all the settings on the amp like the manual specified and started to turn up the gain on the amp and immediately it found distortion somewhere before the first notch mark. That's not even 1/28 of the way up. Not to mention that the DD-1 only detected a signal and not the 40Hz yet. So I shot down to the Best Buy and bought a Kicker DX10001 amp to see how that stacked up against the Alpine and to no avail I ended up with the same result only this time I was able to turn up the gain a little more then the Alpine amp. Has anyone experienced this with any of there amps? I eventually had to set everything up by ear "once again" until i can afford an oscope to insure there is no clipping. I went to Alpines' website and somewhere it states that with there new technology it lowers the amount of distortion i.e. their claim is they have distortion within their product. Anyhow, my suggestion to anyone who decides to by an amp is stay far away from Alpine and Kicker Amps and invest a couple more dollars on some quality products.

C-Fizzy Posted December 27, 2011 Report Share Posted December 27, 2011 Sounds like you're not using the DD-1 correctly. So instead of clowning on companies products, why don't you learn how to use the dd-1 then try it. Because i know i love my alpine H/U. And so what if it distorts at 26/32? better than 15/32. under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy?

Robert8252 Posted December 27, 2011 Report Share Posted December 27, 2011 (edited) Line out converter? Like something that you hook up to speaker wires that then turns into rcas? That's your damn problem. Don't blame it on the equipment. The LOC should have its own "gain" knobs on it. Turn those down and start again.

poorfish88 Posted December 27, 2011 Report Share Posted December 27, 2011 I believe you now have 2 good amps. Maybe not the best amps, but far far from junk. Link to comment Share on other sites More sharing options...

jmilch Posted December 27, 2011 Report Share Posted December 27, 2011 must be a low end loc. But true, it is the loc's issue.

miniSPLlancer Posted December 27, 2011 Report Share Posted December 27, 2011 (edited) Amazing how you are the only one finding these major issues.... NOT TRUE, others are experiencing similar issues, it could be user error though or possibly the LOC, but for example CJ18 is had a problem with his DD-1 similar to this. He talk to D^amoire and it was taken care off Edited December 27, 2011 by miniSPLlancer 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals Link to comment Share on other sites More sharing options...

X 2 Yeah I have ran several different Kicker amps with no problems what-so-ever. I think the real problem here is your knowledge and understanding of what your doing. You should find out before you bash on peoples products. Ever think about how many people here already use Alpine and Kicker? Think they wanna hear their stuff is junk? Especially when it is not!
