Probably one of the things people have the most trouble with when installing multiple subs or dual voice coil subs is when it comes to wiring them to the amp. This post will explain what series and parallel wiring is, a little bit on Ohm’s law, the difference between single and dual voice coil subs, and how to wire subs to different Ohm loads.

How to Select Car Audio Amplifier Kits

Once you have selected your amp, you need to select a car audio amplifier kits to wire it into your vehicle. The amp kit includes power and ground wire, a fuse, remote turn on wire, RCAs, speaker wire, and in some cases a few extras or a few of these components missing depending on the kit you get.

Car audio amplifier installation kits, wiring kits, or amp kits, usually include all or most of the things you need to install your amp, but you don’t need the full kit if you already have most of what you need; you can go buy whatever you’re missing separately. It’s usually a lot cheaper to get a kit if starting from nothing. Also make sure the kit you buy includes what you need. For example: most kits only come with one set of RCAs. This is fine for a sub installation, but you will need another pair if you plan on doing 4 speakers on a 4 channel amp.

Basics to Upgrading and Optimizing Your Car Audio System

car audio basics to upgrading and optimizing your sound systemFirst Steps

Start at the Source
When you are trying to get the best sound out of your system, you want to start at the source and work your way from there. The best speakers in the world will sound terrible if you are trying to stream Pandora through them.

CDs or lossless music files are the way to go these days, although most head units still don’t support lossless files. I would say the lowest bit rate you should go on mp3s is 320kbps AAC. Most head units will support this format, and iPods support this format. Most head units have great iPod support. Win-win.
