i found this, so im passing it on..... Car Batteries What you need to know about your vehicle's battery. Most of us don't think much about the battery in our vehicle; we simply turn the key and expect the engine to start. We expect the battery to be reliable, long-lasting and maintenance-free. Once it fails, however, odds are you'll have to replace it, and knowing which type and size battery you need is important. Will it be conventional, maintenance-free or recombination? Conventional Batteries A 12-volt automotive battery has six compartments or cells. Each cell has a series of alternating positive and negative plates separated by isolators. All negative plates in th…

i am writeing this to try and help people understand what the specs of there amps mean. i'm not a expert on amps but i know enough to write this. when chooseing a amp theres many thing to look at like class a/b or class d and if you need a 2ch, 4ch or mono amp it go's on and on. ....so here it go's.... (in random order) you will need to know if you need a class a/b. class d ect ect. they are many types of class's like a, b, , c, a/b, d, t, x but the one's you see more in car audio is a/b and d. now there are more and more class t amps comming out because the price to build them are going down. CLASS A: these amps have an output device that never turns off, so they are a…

Amplifier bridging is simply using 2 driven output channels to drive a common load. For 2 channel amplifiers, one left signal and one right signal is used to drive a mono speaker load. Keep in mind that mono and bridging are not necessarily the same. Mono means that there's only one output signal. There could be more than one speaker but each speaker will have the same output. Bridging means that you are using more than one source of power to drive a load (speaker). The sources of power are one each output from either channel of the amplifier. A long time ago, amplifiers had signal on the positive output speaker terminals only. To bridge one of those amplifiers, you'd hav…
