Sure seems that way

How did you set your gain?

Are you using an alpine head unit?

Turn the gain down a little and go higher than 25 on the volume.

Sorry, pics aren't fantastic and I haven't shot a video yet.

Pictures don't really show how big this is, lol

Not super pretty, so I'm thinking about making a beauty panel inside the bed

I installed the diode for my alternator today and it didn't change my voltage at all. Even with the system off and batteries charged, it sits at 13.6-13.7v. Doesn't mater if it's warm or cold. I can't figure out why that is. Hep would be appreciated

Also, I'll be adding length to my port tomorrow. It's really loud in the high 30's, but has no lows, haha

PCM regulated voltage..

You need a external regulator.

Not on his stereo Alt ? separate from stock alt or atleast thats what I thought he said he did ? I second alt fed by original stock harness or did wire it on its own ? only needs one wire to an ignition hot source and then diode on the wire that goes to alt output post.

No alternator is self regulated without getting some input from an ammeter or battery temps.

Maybe like the voltage sense wire that we are putting the diode on ? My stock alt is a 4 pin connector and only uses two wires one going to ignition hot source and one to output post and thats stock factory wiring and stock alt keeps my batterys at 14.2 or so and when I switch on the ignition feed two two stereo alts I charge 14.8-15.2 but thats with the diodes.

You have a 98 and older no?

His is a 06 pcm regulated 2 pin system

Ya its a 96.I wasnt sure about his so I told him to hit you up. But if his second alt is a four pin he could do the same as I did ? Its working awesome for me.

He will have to change the reg on the alt to a 4 pin reg and he could do it. Or use external reg as you said.

Even a 4 pin would still need to have the pcm rewired so it can get a line from the ammeter.. Easiest and fastest way is the ext regulator or voltage module.

If you say so ? I don't get why second alt would need to have anything to do with pcm ? Alt only needs to see 12 volts to turn on and voltage sence will tell it when to turn on and off right ? Atleast it's working for me ?

Less lows (because of the enclosure).


On this though, I've got my sub level on +15 out of 15 and the amp gain is about 2/3. Listening volume is at about 25 out of 35 for most songs.

"The other Side" by Jason Derulo on volume 28 is brutal. I can't take the whole song in the driver's seat with the passenger window down. Lows are lacking, but it's strong up top.

I'll sacrifice some upper bass for lows tomorrow and add some port length

I realized that with my alpine hdd 149bt this week also, 1. It doesnt clip at all, 2. The sub vol is actually at 0 when at +15, 3. I was able to turn my gain alot higher also 2/3 seems about the same for me. This was using a dd-1 and cc-1

you had a FK ton more to go then vs previous settings.

Set gain by ear (yeah, I know). I have a scope, but didn't feel like fuckin' with it last night out in the cold.

Also, when I set my M4a with the scope, I was able to adjust it higher later and still stay below clipping after I got a feel for the limits of my system. I don't like that the TFE doesn't have a clipping indicator :/

Yes, Alpine headunit

Ok, I think I'm going to turn the gain down a bit and listen at a higher headunit volume

Yeah, completely seperate from stock and has a 2 pin connector

Then how does a 2 pin connector work? It just has a hot wire and switched source, right? This confuses me

Ok, I can try turning gain down and headunit volume up more, thanks.

What volume do you normally listen at?

 

[adulbrich 5,000+ posts]

Gain is now at half, and I can go to volume 33 at idle before I drop to less than 13v. It does seem a little louder too

For those who will say to "turn the gain up a bit, 12.9v is nothing", I'm babying this amp, haha. Cost me way too much and I'm going to add another alternator before I drop it down to .47 nominal. Right now I'm at about 1 ohm nominal (1.05, but who cares)

Just went to Kmart and got some more liquid nails and some sand paper. About to add some port length
