I have:
Head Unit: JVC KW-R900BT
JVC KW-R900BT CD receiver at Crutchfield.com
Component Speakers: Polk DB6501
Polk Audio db6501 6-1/2" component speaker system — also fit 6-3/4" openings at Crutchfield.com
Woofer: JL 10w3v3 2ohm
JL Audio 10W3v3-2 W3v3 Series 10" 2-ohm subwoofer at Crutchfield.com
Amp: JL XD500/3
JL Audio XD500/3 3-channel car amplifier — 75 watts RMS x 2 at 4 ohms + 300 watts RMS x 1 at 2 ohms at Crutchfield.com
I have everything installed now, but I have no idea what to do with HP/LP filters on the amp, or how to set up the gain.
I used the "ear" method to set gains temporarily. Turned down gain all the way, turn up HU 75% of the way, adjust gain until I heard distortion. Problem is, I never really heard distortion, it just got too loud to tolerate. The HU supposedly has 5v RCA outputs, the amp is 4v? I think? Gain should be low, maybe 1/4 of the way up right? I don't get it.
Also, HP/LP... The Polk components have a passive Xover, so I don't use the HP on the amp, or HU right? Just let everything through, and let the Xover do its deal? The sub, what would be a good slope in a small sealed box? 12 or 24? What xover point should I use? I heard 100 was good for that sub?
LAst, setting my EQ on the HU. Should I set it to my preference, or try to leave it flat? What about loudness?
So may questions. Please someone help a confused soul out.
