[volts at amp going crazy]

i bet getting rid of that 4gauge and using 0gauge will help.

X2 I also have a t20001bd and it draws a lot of current. It comes with a 250 amp. fuse so you know it needs a heavy wire.

[O/scope gain setting help.]

Thanks to all, now ill try to set it with the -10db and see how it does. Thanks.

[O/scope gain setting help.]

With tha 0db test tones it sounds loud but when playing music sounds really quiet. Any ideas? What or how should i set to make it loud on music? Should i use tha -5,-10,or-15db test tones to set tha entire sistem?

[O/scope gain setting help.]

I got tha 3sixty setup cd and my tpi o/scope and started setting all my gains at 0db and my system was too quiet all boosts at 0 and

tried them at -5db and still too quiet what or how to set them to get loud since before triying it with tha scope it was very loud. Thanks for any help.

Btw. i dont have a 3sixty i just have tha cd to set it up.

[need some help on this im out of options]

Are your subs dual 4ohms or dual 2ohms?

[Stinger Voltage Meter]

I got mine with the blue wire conected to ignition switch that way i know whats my voltage even when tha system's off.

It looks real nice.

[This is what a year of SMD does..]

DC Sub looks like king kong to a monkey when compared to tha Audiobahn sub.

Its huge.

[Amp gets hot]

Check the load on the amp with a digital multimeter to see if your final load is around 4ohms.

[Gain overlap]

0db is for competitors or people who are very scared to turn it up on music, no music is this loud, only sine waves

-3db is good for most people, stuff like Dj Billy E and Bass Mekaniks gets this loud

-4.6db is the test tone i use, it gets the most out of ur amp safely on most music

-5db/-10db RF suggested levels... lots of music is louder than -10db... so i wouldnt use that personally

So where could i find 50hz and 1khz tones at -3dbs and -4.6dbs?

[Gain overlap]

Adding gain overlap when setting amp gains is recomended by Rockford Fosgate they recomend a -10 db of overlap for subs and -5 db for fullrange.

My question is what are tha pros and cons of setting with overlap?

[Burning inputs?]

So if i disconect my subs from tha amp and let the sub signal on will the inputs burn?

[How to know?]

Thanks to all of you guys, i've been working and havent cheked those gains but ill try to do my best with all tha info you gave me. Thanks

[How to test resistance with a DMM.]

Set your amplifier gain

Thanks man.

[How to test resistance with a DMM.]

Thanks to both of you! Got a reading from 1.6-2.4 ohms on the amp.

Now I heard you can adjust your gain using a DMM to check for clipping? How would I go about doing that?

I've been triying to find a step by step instructions cause i want to learn exactly how to do it with a DMM if someone could help us with this we will apreciate it.

[How to test resistance with a DMM.]

You should turn everything off and disconect your subs from the amp and conect your DMM to each sub separately thats how i do it. And has worked for me.

[How to test resistance with a DMM.]

You shoul turn everything off and disconect your subs from the amp and conect your DMM to each sub separately thats how i do it. And has worked for me.

[How to test resistance with a DMM.]

Use tha 200 scale.

[How to know?]

Thanks for tha info i will try to do my best.

[How to know?]

Anyone?

Please i dont want to get my subs blown. A friend of mine told me it could be done with a Digital Volt Meter but didnt told me how, if thats true coul someone tell me how? Thanks.

[How to know?]

I just wanted to know if theres a way to know if my bass amp is clipping other than the osciloscope. I tried my best using the traditional level setup that comes in tha owners manual but i dont feel its 100% acurate and i cant afford buying an o/scope.

Thanks for any help.

[What could be my problem?]

Any ideas?

Im asking for help!

[What could be my problem?]

Thank you guys for your help.

Now that i know im in tha need of a new alt wich alt you think should do the work and how much amps?

Does the cap has anything to do with those voltage drops?

Im asking cause its a 10 farad, isnt suposed to help with it or not?

Should i go with an external regulator so i can adjust the alts output to a higher voltage?

Whould it help?

Your help is and will be apreciated.

[What could be my problem?]

Grounds ok.

Im using tha caddy alt since the stock toyota alt is rated at 70 amps and the caddy is rated at 140.

Whould a higher amp alt help me with tha voltage drops.

[What could be my problem?]

Hi im new here and im having problems with my system it consists of 2 rockfords 15s power dual 2 ohms wired at 2 ohms to a rockford T20001 bd, 4 audiopipe 8 inches wired to a boss 1k amp and 4 tweets wired to a rockford 301s

All of this in a 91 corolla 4d im using a cadillac 140 amp alt 1/0 cable 2 kinetics 1-1800 front and a 2400 rear with 10 farad rockford cap, the subs are in sealed, no space for ported. With the car on system off it reads 14.6v but if i turn the music and start playing it goes down to 11.5v what can i do? Also big 3 in 1/0 g. Any help or advice will be apreciated. Thanks.
