boot audio install stupid question time

[oasis6x]

ok, so i bought a car last year with a load of audio in the boot. It consists of:

Pioneer 1000w TS-W306DVC 12" Sub, 1000w max 400w nominal.
www.pioneer.eu/uk/products/archive/TS-W306DVC/page.html

American Pro Bass Machine Amp
400w, 2ch bridgeable,
www.americanproaudio.com/vs-14xx.html

American Pro Power Cap
"Poweramper" 1.0 farad

I wouldnt mind giving the install a go, however:

a) what do i do with the power cap and do i need it?
b) is the amp sufficent to run the sub well?

thanks.

Power cap goes in the bin.

I would run a different amp though.

Power cap will help hold the voltage up / constant ..

Any modern amp will run a modern sub

Is the speaker 4ohm ?
Your amp will only supply the current drawn by the load that is across it .

If the amp is 1000w. @ 1ohm and you put 4ohm across it you will only draw 250 w

So draw about 1/4 of what the amp can do an 1/4 of the current

Remember the earth path is more important than the supply . .

I see it can be 2 ohm or 8 ohm
So wire it using both coils 2ohm . They will give you a drawing of how to do this

Run a fuse close to the batt and a second fuse close to the amp . .

One rule with audio, go simple or go all out. For what youve got, wire the sub bridged across the amp, throw the cap in as its there. Set the gain so you just cant hear a male voice on the sub.. and job done.

I wouldn't bother with the power cap...just something else to draw current.

Take on board the other points about running the sub 2 ohm bridged.

With a little application of Ohms law I doubt that amp is knocking out 500w RMS @ 2 ohm though :-(

[sparkyt]

caps don't draw current they just hold on to the peek voltage to smooth it out . ..

A second battery will do the same thing

I used to run 3 batteries in my nova when I wa a kid
One 15 inch sub
Two 12 inch main speakers
Eight 8 inch mids
Four 2 inch tweets
Made my self 8 x 48w rms ic amps
And ran 2 alternators

The ship rocked

I lost number plates the mirror and my rear light cluster fell out on the drive home from work

in layman's terms the power cap is a must if you wanna drop a very loud 'phat' beat, and not have your lights flash/fade in time with the music

under normal in car listening conditions you'll not notice its effect...

Think I'm going to leave the power cap out tbh after reading up online. Its not going to be the most powerful setup, and it seems that the power cap actually supplies the headlights and systems as opposed to the amp when the alternator cant keep up.

Why do i need a fuse close to the amp as well as the battery? The amp has a built in fuse, and there is a beast of an inline fuse at the battery end of the wiring (ill be installing it today).

Good point on the ground wire through, thanks.
