Superultrahippo's mini audio build

[superultrahippo]

Wait....if you are bridging the amp, shouldn't you be wiring it:

this way:
x_____x
+ + - -

not this way:

x___x__
+ + - -

Hm... thats how the amp manual wires the schematic for a 4ohm sub. I will try that though.

[superultrahippo]

Tried that.. still nothing.

[superultrahippo]

another thing I noticed is if I switch the low pass crossover switch from 12db to 24 db I can hear a "thump" but no sound.

I am not briging the AMP btw. Everythings set for 4ohms.

Im leaving for a bit but appriciate any other suggestions! Wish I had anouther amp to test.

Amp is mono: bridging is not possible, it is one channel.

The 4 terminals are for looks only, which neg adn which pos aren't important.

The markings on the back of the deck are kind of odd...pic of connections? If you get a thump, you should be live. Plug an MP3 player into the amp if you have to.

[superultrahippo]

Alright.. I guess we're getting somewhere. On notes with bass, sub can VERY faintly be heard and felt. Dont know if it's something I did or just didn't notice. I now have it out of the box for troubleshooting.

I've rechecked receiver settings.. nothing caught my eye. The LED on the "bass control" still wont light up. Almost as if sub isn't getting enough power? My connections to and from amp seem ok. I took a couple pics.. I'm starting to think defective amp?

[superultrahippo]

Fuhhhhhh.. I feel like a dummas.
I started effin with the amp settings on the amp itself(not knowing wth im adjusting btw) But i guess everything was just turn too low? It sounds awesome now! Tomorrow i'll spend the morning cleaning the install up. The stupid bass control unit still isn't powering up(led remains off) but it responds to me adjusting it so eff it.

Hey luke (or anyone else).. any recommendations on the following settings?


On the Head unit.. the HPF?
On the AMP:

Level 6v-.2v
Subsonic Filter 15hz - 50hz
Bass boost 0db-9db
LP crossover 12/24db 30-120hz

Thanks guys. I should have pics of finished install tomorrow.

Set "Level" to 95% of maximum.

Set "Low Pass" to about 75 80Hz at 12db/oct

Do NOT use bass boost until you are used to this: that is a woofer eater in your case.

"Subsonic" should be about 20Hz unless you are listening to a bunch of hip hop, then like 25Hz.

You should have pretty major thunder with that.

Almost done! ..my FM reception went to crap though. Checked for loose connection and found all of em ok. Even the trunk one. Antenna extends and retracts.. grrrrr!!!

[superultrahippo]

It get better.. Reception comes back if I disconnect the ground from the AMP. I eff'd up the crimp connecters supplied in the amp kit so I had to do away with them and hook up the 6g power/ground cables directly to battery. Im guessing this has something to do with it?

[StereoInstaller1]

Wait...did you put the amp near the antenna?

[superultrahippo]

Ran RCA's in clear way from antenna harness.. still get static on FM/AM. Goes away when I take out the AMP. Im running out of ideas..

[superultrahippo]

Wait...did you put the amp near the antenna?

No, the amp is on the lower right side of the backpanel..

[superultrahippo]

Well, im all out of ideas.. RCA's aren't even connected and it still happens. As soon as I disconnect the ground from the amp(turning off the amp) reception comes back. Reconnect---goes away. Connections are good and away from interference. I snapped some pics of the set up as of now. Any ideas? ..bad amp?

[superultrahippo]

Hey luke, I have a factory amp. Could this have anything to do with it? I have all 4 speakers wired from the fader. It's not alternator whine. It sounds as if I have REALLY shitty FM reception.

[superultrahippo]

stumped.
