[QUOTE="adulbrich, post: 8768081, member: 661255"] You probably have a regular flooded lead acid battery under the hood. Bare minimum, it might be a good idea to replace it with an AGM battery, if it's a few years old. You may need to upgrade your alternator if voltage drop is bad. Install a small volt meter to monitor your electrical. [IMG]https://images.crutchfieldonline.com/ca/learningcenter/car/subwoofer_wiring/1-DVC-2-ohm-mono-low-imp.jpg[/IMG] Bridging is combining 2 channels of a multichannel amp. The CAB 22 is a monoblock (one channel amp), so you do not have to worry about bridging Maybe someone else can chime in. On the CAB, I'm not sure if it has a "bass knob" that controls just the "bass boost". I would assume like other good amps, it has a "remote gain" knob that would simply reduce your gain but not exceed the setting on your amp itself. Unless you're burping test tones, it will not be pulling a "constant wattage". DO NOT use the "bass boost" function on the amp. It's something commonly misused. I understand there is a "time and place" for its use. However, that's for experienced users who are trying to get a more level sound quality, and gains are set with this in mind. That is definitely NOT the best guide to tuning an amp that I've ever seen. I'm surprised crutchfield would publish something like that. "Play music through your receiver at about one-quarter volume. Turn up the gain of the subwoofer amp until the sound from your subwoofer completely overpowers the other speakers, without distorting." [B]is NOT how I would recommend setting gains.[/B] When you're at normal listening volume, you could be WAY over-driving your sub or amp. Very disappointed in crutchfield. Also, FORGET about using the bass boost function, if I hadn't made that clear. There are several good ways to set amp gains. Oscilloscope is great, but I understand that not everyone has access to one. Using a voltage meter is a good way. There are several good guides to that online. I've used an O-scope in the past, but I honestly just set gains by ear (unless I'm using multiple amps). Be smart about things. If it doesn't sound right, turn it down. If the amp or sub is getting hot, turn it down. If you smell anything, TURN IT DOWN. [/QUOTE]
