Question about Dual 2-Channel Bridgeable MOSFET Amplifier (XPA4100) Car Audio Amplifier
Should've asked more.. LOL.
Depends on a couple things.. I'll try to guide you as much as possible and if you have any question just let me know.
If you are running these subs on a ported enclosure or band pass, do you know the tuning frequency of the box? If it is sealed, I would assume it is 35 Hz + -5.
Also, can you select the frequency for the subs from the Head unit? If so, bring your HU's xover at 50-6- Hz. On the amp itself, turn the gain at 3/4 and you could either get the amp's xover at 50hz or below (that'll depend on your taste). the wiring of the woofer should be in parallel so that you can drop the impedance to 2 Ohms.
The band reject filter is for letting through "other" frequencies than the ones you have specified... which I see it as a good idea so leave it to off,
The band reject frequency, leave it at 40 Hz
Your woofer does great at low frequencies, so the bass boost frequency set it for 60-70 Hz.
Also, since you'll be using this for subs, make sure you have yout dial to LP (Low Pass/Through/Hi Pass)
The high pass dials you don't have to mess with as they aren't used on Low pass.
Something to note. If your stereo has Low Pass frequency adjustment, the amp will already be receiving only low frequencies, so, if you want to leave it in Through (or full) it will not matter, thus I had to admit that this Amp gives you room for seting the audio exactly as you want.
This will be the setting I would use according to my experience and my ear... but, it will depend on your taste as you'll be the one riding it.
if you have any question please let me know.
by the way, hopefully this was useful to you
