A cap is not to replace the batt, just to supplement it. If you want high power can get those like Batcaps or chain up a few caps.
All caps have low ESR rate, but the rate of the esr is still different. It depends on what is your objective, if its for audio, SQ or SPL you will probably be looking at different type and need to pick it more carefully.
i know you need cap and battery.. a cap is a device that charges up (calculated in farads or micro/pico/nano farads for small caps) and then discharges when needed... you wire it in parrallel with your battery (positive to positive, negative to negative) and allows your battery to put out higher CCA (cold cranking amps) basically means that under short/snap periods of high current drain (amplifier while heavy bass beat) the voltage won't drop...
has anyone noticed the transmission shifts much smoother with the additional ground cables?
I have a manual, and no, it is not smoother. :)Quote:

haha.. i'm referring to auto. i wasn't expecting the grounding to have any effect, on power, but did noticed the transmission shifts smoother.Quote:

I got mine done at a shop and looks like they have put it somewhere behind the side rest of the back seat but I don't know how to take it off.
My 4 channel amp cuts out when there is:
1. strong bass in the song
2. sometimes when changing gears
The monoblock still powers the subs fine though so I thought if it was a poor ground it would affect both amps.
I have a 1 farad capacitor feeding both amps/
What's the gauge of your power wire? The best ground is the shortest ground to the chassis, behind the seat.Quote:

Do you have any pics of where to ground it?
Lift up the front of the bottom part of the rear seats, there are 2 clips/hooks in the bottom-front of each seat. Then tilt the front up and rear so you get more space at the rear. Then put your finger in the gap below the side bolster and feel for that 10mm bolt. Remove the bolt with a 1/4" drive ratchet and extension, then lift the bolster up and pull out towards the front. Putting it back is the reverse and it is much more difficult to get that 10mm bolt back in. :) Also, when you push down on the bottom seat, make sure the hook lines up with the clip before pressing down.Quote:
