Question about Lanzar OPTI1222D Car Subwoofer
I suggest we go for 2 ohm to preserve the amp and not heat things up so bad.
Your Subs are Dual Voice Coil(DVC) and 2 ohms each coil. I am going to tell you the wiring to insure you get balanced response from both Subs. We will wire the Subs Voice coils in Parallel to make them 1 ohm each. Then we will wire the Amp to the subs in series to make the total load on the amp 2 ohms. When you have series to both subs each sub gets the same current.
Example of my coding :SUB1VC1+ = Subwoofer 1 Voice Coil 1 Postive terminal.
SUB1VC1+ to SUB1VC2+
SUB1VC1 - to SUB1VC2-
SUB2VC1 + to SUB2VC2 +
SUB2VC1 - to SUB2VC2 -
AMP + to SUB1VC1 +
SUB1VC1 - to SUB2VC1 +
SUB2VC1 - to AMP -
This should give you a good repsonse.
Adjust your Bass Gain down very low at first. Also cut you LPF to about 60 hz. Crank up the volume on a bass test Audio track, Adjust the Bass Gain up unitl you get distortion. The turn it back a little. This is proper setting for your Gain.
