2009 aveo5

running a 1200 watt rms x1 at 1 ohm amp and a 60x2 rms amp for the components

slight headlight dimming when system is cranked

running 1 12" sub now soon to be a 15"

suggestions???

get a good battery and an ho alt

would a new ho alt be enough.. the stock is 95 amps

Have you done the big 3 yet? If you are only getting minor dimming right now it is possible this will take care of it. If you plan on adding any more equipment you will have to do this anyways so you might as well get 'er done.....

I would leave the expensive solution until after I had tried the cheap one, but that's just me.....

as it was suggested do the big 3, especially if your aveo has air conditioning and power everything (window's & locks) . Do this first and foremost, as mentioned previously this is the best thing to do especially if your going to add more to the system down the road, if your not going to add anything else, still do it, the results are worth while especially for the little cost involved in doing the big 3.

I just put a 200 amp alt in my Jeep, which is more my thing when compared to audio lol, but with just a HO alt you shouldn't have a problem running your system while the car is on but a better battery would definitely let you play around a bit in in accessories.

Why is it called the Big 3? Where I come from its just called upgrading your wiring

Because it is the 3 connections that affect your voltage levels under heavy current draw the most. The makers only put heavy enough wire on those points to run the car and it's accessories. If you add a system that may double the current draw at high volume the wires will not be able to supply enough current to prevent voltage sag, which will have an adverse effect on your car and your audio system.

It will not solve every dimming issue but it is mandatory to do this if you are adding a substantial system to your car. Even if your present battery and alt are in good shape the choke point in the current flow is going to be in those wires, so adding extra capacity helps keep things working to their maximum potential.......

Also, for the record adding more generating capacity without having a wire network that can handle the extra current flow is a bit like putting a V10 in a Neon without upgrading the tranny and the tires.....

Not to mention the bad things that happen when wires get overloaded (and hot).

All wiring should be in 1/0 (except speaker amp of coarse)

Extra batt in the trunk.
