Agree ako na for your 1st time, get a car audio installer to do it for you. Watch them and ask questions. Best way to learn. Better than trial and error.

On its simplest, steps and materials needed to install an amp:
1. disconnect battery - both negative and positive
2. position your amp
3. connect a power cable from + terminal of amp to the + battery terminal. Guage 8 or thicker. Thickness depends on the length of the cable and power needed by your amp. This must be fused within 12 inches of the battery. The amp manual usually says what size of fuse you need. Note this fuse is to protect your car and not your audio equipment.
4. wire your amps remote turn on to the your HU remote turn on wire/output
5. run rca cables from your hu to amp
6. wire your speakers and crossovers.
7. run a ground cable from - terminal of amp to a ground point in your cars body. I like to use same size wire as my + cable. You have to scrape off the paint for a proper ground. Ground must be touching bare metal.
8. reconnect + and - battery terminals.
9. Pray you did it correctly and nothing blows then turn on your hu
10. if it works and your car does not burn to the ground from an electrical fire (joke) set your gains, balance etc...

There are some more technical stuff but thats the most basic way of installing an amp. You also need guts to strip your car of door panels, carpet sidings etc.. to hide the wiring. Tip - put your screws and clips in a container so you dont loose them. Tke note where the screws came from. Very frustrating when you have reassembled your car then find out you still have screws that you did not put back. Trust me I've been there.

House speakers are normally 8 ohms. Car audio is usualy 4 ohms. It will work, but you will loose about half the power of your amp. So if your amp is rated at 200 watts at 4 ohms, your home theater speaker will only get around 100 watts. This is if your home theater speaker is passive. If your home theater sub is active or powered, you will need a 220 volt power source from your car.

mas advisable na hindi sa engine bay located ang fuse ng amp kasi lulutong in the long run ang plastic casing ng fuse.
this may lead to accident can cause short circuit/fire kapag nabasag kusa ang plastic casing at sumayad ang positive wire sa metal surface.

I disagree. The fuse should be as close to the batt as possible. Kung somewhere else ang fuse ang haba ng unfused wire papunta dun. Greater chance of shorts. Get a good quality fuse holder that can withstand the heat of the engine compartment.

The fuse must be located as close to the battery as possible. The fuse is there to protect your car. Just use a good quality fuse holder and properly sized fuseand your good to go. I've been dabling in car audio since the early 90's and I've never had a short bec the fuse got wet. Its also a good idea to wrap your wires with split loom. Protects the wires while maintaing a stock look.

Advice: Seek a professional car audio installer and save yourself the hassle. Invest the time instead elsewhere. Since even until now, I still get headaches on where to look whenever noise starts popping up during my install. So kung may tumopak, you get to blame the installer. Trust me and save yourself a couple of future headaches.
