Car audio questions?

Question:
I have a few question answer as many as you can please... what does bridging mean, and ohm mean and how do you know what watt amp will work with a x amount of watt subwoofer?

Answers:

How do i adjust treble and bass in my car?

Bridging is a type of connection when you use the (+) terminal of one channel and the (-) terminal of the next channel. For example a 4 ch amp can be bridge into 2 ch amps but with double amount of power. In other words the power of 2 ch are now into 1 ch get the point? Ohm's law is a circuit theory law that state voltage = Resistance (Ω ohms) x current (A amperes). Ohm was the name of the scientific who invented it. With that single law you can calculate power, voltage, current , resistance, impedance, conductivity etc. For the sub always try to match your sub rms power with the rms power of the amp. the rms is the real value for the systems specs. Ignore completely the peak max power

Car audio question. Need pros.?

Bridging is the term used for electronicly joining multiple channels of an amp. It "puts them together," combining their output power. Ohms are a unit of resistance, how difficult it is for electricity to flow through the speaker's coil(s). Having too high of a resistance will severely limit the power your amp is capable of producing. Having too little resistance will look like a short circuit to the amp, and it will shut down and possibly be damaged. Follow the amp manufacturer's specs. Make sure that you match RMS power ratings between you amp and woofer(s), not maximum or peak. If you buy a 300 watt amp (300 watts RMS at x ohms bridged mono), than you should buy a 300 watt RMS x ohm woofer. If you want two woofers, than buy two 150 watt RMS 2x woofers.

I want ssum subs in my car?? need some help?

Example:

How do I take out my stock stereo out of my 2003 Nissan Altima?

Amp - 500 watts RMS @ 4 ohm mono

Can I splice aluminum and copper wires?

1 subwoofer - 500 watts RMS 4 ohm woofer.
2 subwoofers - 250 watts RMS (each), 8 ohm woofers (each)
