Go ahead and smash me all you want I bought a sony . I had one just like this on 2 Phoenix gold 15'*. It was sweet till it all got stolen. What gauge power wire should I run it with? I was planning on using my 2 gauge but I think that'* gonna be a pain in the *** to tuck and make it look good. Any suggestions will help.

Take a peek at this:

(sorry about the ads)

To determine the current of your amp use this formula:

Max wattage / 12 = Max Current.

Example. 650 max watts / 12 = 54.1667 amps. We'll say 55 amps for the sake of arguement. This means that you need a minimum of 4 gauge wire to run from the battery to the trunk.

These are minimum requirements supposedly from the IASCA rule book.

junk i had one and blew it up once a week

Don't feel bad i run sony all the time and know what it feels like to be smashed on rhalford. I would use the 2 ga but if you find something else use what works best for you.

I used 2 gauge when i had them hooked up. If that amp does make rated power then you should be about fine with it. I think they will be a little under powered but they will last forever like that too. Remember to take the reat 6 by 9s out. thats how i had it when you listened to them when you came over. All the preasure from those subs will destroy them anyway

Yeah I've seen sone 6x9 cones in pieces what a trip.

4 gauge will be fine. If you plan on adding more amplifiers down the road you could go with 2 gauge, but 4 gauge is a beefy wire. That will be fine for now.

And BTW you shouldn't knock Sony too much, they have one of the biggest R&D labs in the electronics industry. They are a VERY powerful company with a huge budget.

I did some looking up cause I thought max wattage rating / 12 was a bit large, and to my astonishment, the actual wattage consumption of an amp at max rating is MAX RMS / 10 !!! I learned something today.

Anyhow, I like Sony for a lot of reasons:
1) reasonable prices
2) quality
3) looks
4) variety of products

It'* nice to have a company that makes so many different electronic gadgets, and to know they will all work together flawlessly That'* one of my biggest concearns...

RMS is an DC equivalent rating mathematically calculated for comparason purposes. Since the signal coming into and leaving the amp is AC, peak and peak to peak ratings can be somewhat misleading. This is why Root Mean Square (RMS) values are used. Your formula is probably acurate but electrically speaking, the current flowing through the power wire should be calculated with the amps maximum power rating. Technically, it should be max power / 13.8 or whatever your alternator voltage is but when using 12 volts your result is a comfortable overestimation of total current.

Ohm'* law is Power(watts)=Voltage X Current so Max current=max power / voltage.

That 2 ga. should be good.
Where do you plan on running it? I got a ton of cable strung through my car it doesnt look messy till it gets to the trunk.
