Have you had your battery/alternator checked out? Are they charging/holding charge ok?

Does it happen whilst driving? I'll assume it is...Once your car is running the alternator plays a very large part in powering your cars electrics. In fact, you can actually disconnect your battery once your engine is running. But don't do it, as it is dangerous. [:0] It might not be as simple as replacing your battery.

Um hes got a 899cc cinq, it does that even on my 1108cc Sei.

Being as the batterys on Cinqs/Sei's are just about AA size this unfortunetley happens when the tunes are turned up.
I don't know about a bigger battery as theres not alot of room, but you could go for a split charging system and have another bigger battery in the boot, with the two batterys it should help if not cure it.

Happens on my Bravo too. It looks like a mobile disco, lol. Try a power cap. Heard they do the business

Yeah a power cap should be your first option.
You'll need 1 Farad per 500watts of amp power.
If your still having problems then its time to try using an uprated battery and alternator.

Si.
2.0 20v HGT + £2.5k of stereo + NOS (soon)

Get a 1 farad power capacitor. Put it as close to your amp as you can. Ebay do some good ones. This will sort the problem out. you could look at red or yellow top optima batteries. you'll find these are well expensive but will definately give you more than enough clout!

NO!!!! NOT A POWER CAP!!!! That's just something else to charge!

The dipping of lights is caused by a voltage drop in the charging system.

Assuming everything is in proper working order, a way of curing the dip is:

yeah, aren't power caps meant to store charge and then release it to keep the power supply to the audio equipment constant in order to prevent damage?
