Go to this topic. Wayne explains how to set your gains, without any tools. Read the whole thread, very interesting.

Well, I just read through the thread but I'm wondering if I could just put the bass at a fairly high level, then put up the gains until the sub sounds bad, is this a safe way to set the gains?

Just wondering, cuz thats what I've always been told.

Current setup:
Sub: 15HC
Sub amp: Lanzar 1200D
Box: 3.33 ft^3 ported tuned to 33 hz

I assume your DEH has separate pre-outs for your sub amp, along with a separate volume control. If so, then you set your gain on you sub amp, by ear, correctly. How are your mids and highs running? You should basicly set them the same way, in order to balanced your system out. But, as long as your happy with the way it sounds, and none of your speakers are distorting, at a volume level your happy with, that's all that counts. Having system hiss between tracks or silent passages in your music, is a good indicator that your gains are not set correctly. In a well level setted system you will here complete silence between tracks and silent passages, when your volume is set at your high listening level. If you have a little hiss this may be ok, only the best SQ systems will achieve 0 db during silent passages.

Well, I HAD a cheap MA 100 x 2 amp for the highs, yet my stock electrical system couldn't handle it, so I have yet to hook them up to my head unit.
