Amp hurts ECU?

[mtam22]

I've just finished installing a pair of Blaupunkt VR2100 amps (2x200WRMS each) in the trunk. Before I managed to install the capacitors, I start hearing tales from my friends on how such a pair of power hungry amps could destroy my ECU and alternator even with two 1.5F caps installed. Any truth in this?

If you drive a hyundai getz (already everyone pitties you) then ypu definately need to look at a 2nd battery, I drove 1 for work, and had a sub in the back, when I had the sub going to loud, the car was unreliable, it would sometimes switch completely off and I would need to get out, d/c the bttery, re-connect, adn start again.

Apparently, it tripped the safety surge switch (thats what the manufacturer told me anyway).

ecu should be fine, depending on what you are running. unless its like 10 subs or so...2 1.5 f caps will hold it easy, just get a good battery like a oddesy or optima. skyline bateries are known to be shit, as is mine, and having a reliable battery would be a god send(i have no $$$)

i had an excel with two subs running off an oddesy and it never went flat or showed any signs of weakness(lights dimming)

i have a optima yellow top in my skyline, and never seen pulsing and holds a nice 13v+ even when the stereo is cranked up at the lights. well worth the money.

The caps are there to filter out any spikes and also to decress the pulse demand on the battery and alternator. With a decent battery, like the optima, and the two caps that you have stated, you should NOT have any trouble.
