Just yesterday, my sub amp died in my car. Anyways, I had extended warentee on it, and when I brought it back, they gave me a better one as they didnt have any of mine in stock.
Before we get into the details, im definitly a newbie here. I like building enclosures / boxes and stuff, but I dont have much technical knowledge of this stuff. When I wired up the 1st amp, I followed the directions to the letter, but used bigger wires than reccomended incase I wanted to upgrade.(4 gauge power and ground is what I have in.) This amp had bad instructions.
The new amp is an MTX 4202. Its still quite a low end amp, but its definitly better (Its 200w x 1 compared to my old 120w x 1), and should pound my car much more than my old one did.
I could probably put it in with about 15 min cause the wires are already there. I want to have my subs back!! Anyways, Ive yet to hook it up cause im confused. This amp has a "GAIN" knob that im not quite sure what to do with. My old amp did not have one. My question is, do I need this GAIN? There are no numbers on the knob itself, so how do I do this? I think it has to do with the headunit preout voltage, right? How much do I turn the knob? Is this some sort of guessing game?
According to the manual that came with my headunit:

Preout maximum output level / output impedence = 2.2 V / 1Kohm

Heres a pic of the amp that I found on the web, so you can understand about the GAIN knob.
Audiophiles....no laughing at my amp / subs setup.
The old one sounded pretty good to me, and this should be even better. Im on a pretty tight budget, and not looking to give the whole street a headache from my bass.
Any and all help appreciated.
