I appreciate the offer, But I use TrueRta to do mine.
I'm sure there are others on here that would jump at that offer, though

For tuning the amp "the correct way is to use an oscilloscope". Not sure how to without one.
Personally I would run new wires for them. Just because after spending so much on the components it would be a bit of a waste to not go ahead and run new wires. JMO though.

thank you haha! and do you have to buy one or can you bring it to an audio store and they do it for a price?

Do you use a laptop to do it with TrueRta? and is it an accurate way to tune the amp?

Yes a oscilloscope would be the best way to tune an amp. However with most people not having access to them nor knowing how to use it.

You can either tune your amp with a volt meter or by ear. Doing it by ear you have to listen for distortion and than back your gain off slightly. I have been doing this for years with no problems.

Amp Settings and Gains

So great you got your new amp and are wondering what in the world are all these knobs and switches on it for? Well here is your answer. Gain or volume. Some even say it differently than that but the deal with this is, think of it as a adjustment to insure your not clipping the signal. When you are all done installing your system is it time to put a test disk in of a normal song or a test tone of 80HRZ go to your amp and turn the gain all the way down than go back to the head unit and turn the volume 1/4 to full volume. Now you go back to your amp and slowly start turning up your gain until you hear distortion than turn it back just a hair. This will insure that your speakers are not going to distort or clip.

Now those Low pass and High pass knobs and all. Well a normal setup consists of your fronts being components. "speakers with separate tweeters" So the crossover will take care of the filtering of all that so your front should stay on Full. If you are going with rear speakers I would turn on the High pass filter and dial it to around 80 or maybe a bit higher. What these filter do are basically insure that the speaker will not get frequency's that it can not reproduce. The Low pass filter is fro when running a sub woofer your cut off should be around 60 for your sub.

Alright thank you I think ill just end up doing it by ear!

RonRizz 12-01-2012 08:46 PM

I would never recommend a novice set amp gains by ear.:shakes head: Especially for a sub.
stay the simple course and use your multimeter.

:iagree:
Simple. almost too easy. there are literally dozens of videos on youtube you can watch and learn as well.
just search it.

arnoldas 12-02-2012 08:12 PM

Alright haha thanks

arnoldas 12-04-2012 01:40 PM

Anyone know what the best way to wire the two subs to the mono amp would be?

RonRizz 12-04-2012 05:04 PM

s e a r c h lol
