what should your volume be set to on the head unit when setting the gains??

[jasondigos]

Set the head unit to the max unclipped level. find this with an o-scope.

[jasondigos]

It is a blow thru. we will post pics and vids soon! thanks

thats a cool tool, what rockford should do is build that into there amps so it can auto adjust itself, a new smart amp.

For those that don't have a $2000 O-scope, an alternative, just as effective method is available using a $15 DMM and a free downloadable test tone.

Contact sparky3489 at yahoo for more info.

I went to the website and cant find the download one u said

[stratdude83]

yea but what if you dont have a $300 o-scope...

[xXjaketotheman737Xx]

Use the smd dd1

I dont feel like buying a 400-2000$ meter... is there another method I can use that is a little more "cost effective" for us cheaper folks, to get the same turnout as using a meter? thanks! :)

hello, ive got some cdt hd52 speakers 90watt rms and there powered off a 4 channel vibe spacebox amp, 400watt rms. they distort when headunit is turned up past about 3 quarters of the way up. the gain on the amp is set at min. what roughly should i set the frequency at? dont no why they are distorting. have crossovers that came with the speakers. set to hp on amp 2 channel on amp. realy need help. thanks in advance

@kyle279andrew usually around 75% of max level.

Maybe RF should re-write the instructions found on page 9 of the Punch Amp owners manual. Does everyone own a O-scope?

[sounduser]

@sparky3489 Frequency does seem to change! but only when you're turning the gain up way too much! the 1000hz test tone starts to creep toward about 1200hz.

ive been using your chart for about a year now, (i found you on yahoo answers) ive also got an oscope. but i wouldnt recommend anyone buying one. good amps doesnt clip before the stated wrms these days.

[sounduser]

why do some people use a 0 db test tone and some people us -5 db to fine where the sub out of the deck is clipping??

[sounduser]

@teamfapa dont worry about the ohms.

20 volts is 100 wrms @ 4 ohms, 200 wrms @ 2 ohms and 400 wrms @ 1 ohm.
