Amp hurts ECU?

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)

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.

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
