Audio guru's advice needed

[Wes Harden]

I am not a car audio efficientato, and I have noticeable hearing damage. 35db above 4k and 20ish db 3k. Am supposed to wear hearing aids. Let me tell you boys and girls Hearing aids suck.


So any way I have custom Audio sound USA-630 head in dash w/ bluetooth add on. Some 6.5 2 way speakers in the lower front doors, 60w rms. Nothing in rear atm. In the past there were 2 6x9's. 1 in right rear barn door, and 1 behind left rear seat, near rear wheel well. Seemed poor placement to me. I plan on putting rear speakers. Not sure where. don't want boxes taking up real estate in the back either.

I do want to add an amp, to clean up the sound at lower volumes. If in the truck alone, I run the volume at @75-80%. If the little women is with me 40-60% depending if we are talking.

I was looking at this one. https://www.crutchfield.com/p_613KAM1814/Kenwood-KAC-M1814.html?cc=01&tp=115.

I want small so I can put it out of the way. Would placing an amp on the inside firewall, where possible heat from heater, or transference from eng/exhaust be bad on this amp?
Can anyone explain the settings? Filters, sensitivity, Freq. and what will adjusting them do.

Mounting it under the dash would work, but under a seat would be better.

I am considering building a plate form for my center console cooler I might be able to fit an amp under that.

What about the adjustments ?

The gain or sensitivity Is hard to set right by ear. Best way that I can say to start is set the deck volume about 1/2-5/8 of the way up. Then turn the gain up to mid way and see how it sounds. Turn up the gain from there NOT the deck volume. Get it as loud as you'll want it, trying to make sure the speakers don't start distorting.

High pass filter blocks crazy low bass from trying to go through your little speakers. Usually for 6.5-6x9 with no sub I go 60-70 hz.

Shouldn't have to worry about any other filter stuff.


Set the high pass filter before you set the gain.
