Amp Tuning

[Sqwirtle]

All went well. I re-wired the wires. Taped them out of the way. Made the remote turn on longer, etc. And now the alternator whine is gone.

I played with the settings a little and will probably continue to do so in the future.

I took out the resistor as well - the chimes and blinker volume is fine. The only problem is that when I push the voice command button, and she goes "Please say a command." That is very freaking loud. (this is the MyLink 2013 w/nav) I'm not sure if a change will be needed to harness for newer cars or what to take care of this.




And my caliper job went beautifully!

Pur3vil,

That was a great write-up with lots of information. I appreciate you taking the time as I am sure that it may also give Sqwirtle some information that could be useful. I know that when I do self installations I like to try to read and take in as much info as possible, even if I don't use it all when I am doing the install and run into an installation it is nice to have a little background. Thank you again.

Sqwirtle,

That looks great, the speaker and amp and the caliper job.

Just a quick comment This thread came just in time. I'll be installing my amp tomorrow so now I will need to ask about tuning the amp. Thanks

Your amp settings should be set according to what the speakers take. For instance, your subsonic level, if the box says the sub plays 38hz-200hz, your subsonic should be near 38hz. This prevents the speaker bottoming out and damage to the speaker. The lpf on a sub doesnt really need to be above 80-90hz because your mids should take over the notes from there. I always run my 4channel amps on my vehicles and customers vehicles at full as long as there are enough tuning options on the amp. You do the same with the mids as the sub, tune to the lowest playable hz according to the speaker specs. As far as gains go, i've oscoped camaros before and the head unit volume was around 35-38 for peak. Set to that level and adjust your amp gains for best performance. For amps to be the most efficient you want the gains as low as possibly required. It cleans up the sound and increases the longevity of the amp.

For the Polk DB1240 that comes with this kit, the specs say that the sub handles 27-200 HZ, so it looks like sub sonic should be set to just under 50% and LPF should be set to somewhere around 85-90% to avoid damage. But as DraggnFrameGMC states, you can set the LPF much lower if you have coverage from the mids. It's always nice to hear from someone who knows what they're doing instead of those of us just muddling our way through it.
