Car Stuttering And 4wd Turning Off On This Song

[GTAAAH]

One of my mates sent me this song on msn the other day, has some really low frequency bass on it (makes u feel sick after a bit), and sick bass across the range, anyway.. I was driving with it on (got a kenwood excelsior sub and a 500w mono block kenwood amp, new one worth 450ish, gains only at like half so it's not insanely loud but bassy) and was coming onto boost when my 4WD turned off and it started spinning.. i was like wtf, never happened before.. Anyway, so like 20 minutes later i turned it up again, was just cruising on the high way, and the car started stuttering, turned it down went away.. then another 10 minutes same story but on acceleration

Anyway, i don't honestly think it's a power usage thing (brand new larger than standard century battery), the lights aren't dimming at all and i listen to hardstyle (which has very consistent low bass) and rap with the volume up as loud for far longer than i listen to this one song..

Anyway my question is, could the bass being low frequency be screwing with my hicas system somehow? like the G sensor for the 4wd system is in the boot isn't it?

Wiring is all good, it's not wrapped around my ecu or anything, and i dont notice any of the other effects of not having enough power going to sub/amp (my old golf used to almost turn off when the bass kicked in)

willing to upload the song..

It's no biggy but i just thought it was weird.. might have to look at a capacitor if it's screwing stuff up, just odd that nothing else like the lights seem effected.. and that it's loud but still only half gain up

if I had to guess I'd say the bass was shaking a connector that has a dodgy contact.

there are fault codes when something like that happens so provoke it and scan the car,

it might help identify what bit of the system is losing.

Ahh yeh didn't think of something like that.. Guess it would have to be actual ECU to be causing 4wd problems *and* stuttering problems.. ecu is ages away from it though.. i'd have to run the diagnostics while the bass was on i guess? Never ran them before because they're so difficult to get started ;p

sounds like the easier option is not play the song.

This is true, just had me totally confused, thought it might be a common problem, low bass frequencies screwing with in car things.. i want to turn the gain up on my amp more (theres a fair bit to go) but i'll have to sort out exactly what is happening first i guess

cheers dude
