150A would be nice.

Caps on any sub-woofer equipped vehicle are a good idea. I would not install without one. Caculate your entire load at max capacity and judge for yourself. A single, 1 farad bank should help smooth out the demand on a dual channel, 600watt sub easily. Running bigger capacity subs and amps, you will need more than one. At least, you cannot have someone at a mechanic's or dealership point at your stereo and blame your bad alt on it if you got the capacitor(s).

Yeah,
I have my outputs bridged so I "could" run at the 380W continuous/ 760 W max that the pioneer website states (I have 2 12's@ 8 ohms paralleled to 4 ohms). I didn't think that this was too much power, but I guess I should look into buying one of those outragiously priced capacitors.

1 farad per 1000w

That means a 0.5 farad will do the job.

On ebay you can pick up a 1 farad cap very easily and cheaply and I have one on mine and it really tightens up the bass response.

Also, you might want to go away from Pioneer amps for subs, they are not very good and low power.

Trust me, I had a 500watt RMS Pioneer amp and it wasn't putting the power out that my 250watt Kenwood amp was doing.

Sorry for getting defensive, but I got the amp used off ebay and I've had excellent luck with it. I haven't turned up the preamp gain at all and I keep it on low gain from my alpine head and it is plenty loud and produces a quality sound. I wouldn't ever use more power if I was given it. I have had excellent performance from my pioneer.

I just need a capacitor and a new alternator pretty soon. Thanks for the help!

What is powering the subs?

[chcknugget]

Pioneer GM-X862

Looks like a nice amp and sems to be priced cheap.

So you have two 8 ohm suns in parallel hooked up to this?
