I'm a real bass head. My main listening content is drum n bass and currently have a 1200w inphase sub and 900w Amp fitted.

Now, ive had the problem of the headlights / dash dimming for a while when the volume gets pretty...Ahem, LOUD. This is slightly annoying.

Rather than just bodge with a powercap, i'd like to do the job properly and fit a better alternator to solve the problem.

So the question is, where do i source one from?

Cheers.

Carn't see a bigger alternator making much differance as it still won't be able to react fast enough to stop lights dimming,

I wouldn't call a power cap a bodge as thats what there designed to do once there charged up as they can release power alot quicker than a battery or alternator ever would be able to

My sierra used to do it

Was gonna say my sierra used to do it till I put a transit battery in and it cured it

I have a 150amp yummy shiny 1

And a cap

Add that and try a optima bat mate so the power flows rather than pulses then go from there

But then its split charge fiddling im afraid

Pop me your email in a pm mate and i'll forward u my receipt lol

I sent a pic of it to dave

Easier than hunting lol

Power caps are a large farse they aren't efficient enough to stop the dimming you will find that after 5 minutes of booming the lights will dim again

The best solution is a large alt and a second sealed battery in the boot

Diesels have larger rated alternators than their petrol counter parts.

Mine in a 90A unit (038 903 023 L)

I agree with this, split charging system would work best for bigger systems, you could use a deep duty cycle battery in the boot right next to the amplifiers.

I used to have a split charge system in back of my volvo when i was running 3 amps in it, i also had a switch up front aswell so i could control it
