Amp And Sub Install

[skylinesome]

Hey guys installed a amp and 2 subs on my car and was wondering what guage wire you should use from the sub to the amp?

I just cut up some RCA Wires and hooked it up with them but the subs sound like shit. There not loud at all and sound very distorted, they havnt got the puch of a sub. Any Help would be good.

I have a mono block amp with 3000 watts

and 2 12' 1000 watt subs hooked up to it.

you need this:

that will ensure everyting is working properly.

give us a rundown on what else is in the chain.

I have 4 6" speakers and a pioneer head unit.

I have hooked up the amp and sub it sounds awsome but when i turn the key off I get a loud pop from the sub.

Anyone know what this is caused by.

Your turn off pop could be caused by a lot of things, the main offender is a cheap chinese amp with inferior circuits.

but.....

As your amp is running 3000w rms (claimed) to 2 x 1000w (claimed subs) a prefab box and power kit off the shelf will be no good at all.

You need

Thick Cable.

0-1 guage for power and earth

0-1 guage for earth from battery to chasis and upgrade of alternator wiring

4-8 guage for speaker wiring

10 guage for remote amp tunr on

and rca's would need to be something good, stinger, etc. (dont buy the cheap ones)

If they are 1000w (claimed) subs you will also need to make a fibreglass reinforced mdf enclosure for them. No point spending all these $$ on the good stuff and putting them in a crappy box.

Boxes that have fibreglass reinforced mdf are always custom made. Which is the ideal enviroment for a sub or two anyway.

I would budget $800 on the wiring and another $500-$1000 for the box ( depending on the quality and design)

There is a stack of other stuff, lines drivers etc.

But i'm guessing by now your a little scared by this. So here's what you do.

Quote the rms figures not the peak power figures.

Quote the distance from battery to amp in cm's

Quote the type of enclosure the woofers will be in (needed to establish power handling requirements)

Tell us a little about the bass response you are after

And finally, model numbers of the equipment.

Then...

Well then i can give you a little less scarey answer.

scary alright.

Subs sound good man but just the loud pop when turning it off. It does not do it when you turn it on but.

When you say upgrade the alternator wiring, could you elaborate a bit more?

What i mean is to have thicker cable between the alternator and the battery so that more current is allowed to pass to the battery and help to charge the car more efficiently.
