Hey guys, im new to the first post here. Im new to the forum and I just got a JL Audio CP112-W0v3 12" slot ported box and a JL Audio JX500/1D amp. The guy that installed it told me to leave the EQ on the headunit at flat. but quite frankly it sounds like factory. I didnt pay $700 for factory and personally i think that is BS. i cranked the EQ up a lil and boy what a difference. this thing is niceeee. my question is, will this damage it? and do you guys have any idea how i could fine tune it to protect my investment. Oh and btw i have a JVC KWR710 head unit in a 2003 Impala. Thanks in advance.

sure. i just took a look on crutchfield for the specs of the HU.

heres what some of the specs say and forgive me for being a beginner but i barely understand any of this, but im trying to learn.

2.5V/4CH Preamp Output: two pair of 2.5V preamp outputs (Front, Rear/SW). You can set the Rear/SW preamp outputs for connecting a pair of full-range rear speakers (through an external amplifier) or for connecting a subwoofer (through an external amplifier). When set for rear speakers, the rear outputs operate with the unit's fader control. When set for subwoofer, the outputs are non-fading.

Subwoofer Controls: When the unit's Rear/SW preamp output is set to Subwoofer, you can set the cutoff frequency of the low-pass filter at 55Hz, 85Hz, or 120Hz. You can also adjust the head unit's subwoofer level between -8 and +8 (separate from the main volume level).

the unit has a low pass filter so im not exactly sure how that works.

Bass EQ's 60, 80, 100, 200 Hz +/- 12 dB (-6 to +6) with Q 1.0, 1.25, 1.5, 2.0

Midrange EQ's 0.5, 1.0, 1.5, 2.5 kHz +/- 12 dB (-6 to +6) with Q 0.75, 1.0, 1.25

Treble EQ's 10.0, 12.5, 15.0, 17.5 kHz +/- 12 dB (-6 to +6) Fixed Q

Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)

Maximum Output Power: 50 watts x 4 channels (200 total watts)

Don't mess with the EQ. Leave it flat. You don't know what you're doing, and it should only be used to cut peaks

google up "how to set gains with a digital mult-meter" and set the gains properly. Most dealers set the gains on the extremely safe side so you dont blow anything.
