Need Help in Tuning

[Italyix]

Hi all.

I am new to this forum and juat installed my system. I am new at this so bear with me.

HU: Alpine 9885

Amps: Arc Audio KAR 300.4 and 300.2

Crossover: Arc Audio MX-1

Speakers: Morel Hybrid Ovations

Sub: Arc Audio ARC12D2

RCA's are for a home theater, Proflex is the brand, gold plated terminals. Wiring is monster cable.

I have the speakers in the stock locations, tweets in the A pillars and mids in the doors.

For some reason, the sound is not what I expected. Can anyone help me with the crossover settings, gains and such?

Right now I have the active xover set at 65hz for the sub with 1/3 gain and 80hz for the mids and highs set at ~1/2 gain. Amp gains are set to min. I also get static noise through the speakers at low volume. Does this have to do with the fact that I am not using car rca's but rather home audio rca's? Its like my tweets are flat and am lacking mids, really bad. Will insulationg the doors help?

Any help is appreciated. Thanks in advance,

-Andrew

Edit: Forgot to specify that I am looking for an SQ setup, not SPL.

booo for apillar tweets.. try putting them in the kicks - i bet they blend better and help the mids stand out... and deadening your doors *can* help

Static noise is likely due to a bad ground. RCA's are RCA's... doesn't matter what "use" they're for. It's all the same.

Did you do the install yourself?

How? The car is a Mitsubishi Lancer. I wanted to put them in kicks, but do not know how.

Yes, I did the install myself. Bad ground u think? I have the amps grounded to the chassis, maybe the HU is grounded bad?

Money's still on bad amp ground. Did you sand away all the paint and attach the ground to bare metal?

Yes.

Have you checked all RCA connections?

Go through and disconnect each RCA to make sure none of them are faulty. Make sure not to "hot swap" them though as you can damage the headunit.

This "static" sound... it's not alt whine is it? Care to explain a bit more?

how? get a screw driver lol.. but seriously before you hurt your car... try it with velcro

When I turn the volume to zero, I can hear a static-like noise. It also happens when I turn the gain higher at the crossover. The higher the gain, the more noise I hear at hogher volumes.

[Etac 10+ year member]
