I haven't bought the cable yet, but there seems little point running a dizzy block given the tiny distance from battery to amps.

A line of 4 & 8 off a terminal block with inline fuses seems to make more sense and less wiring.

[mini-luke]

Yes, with a Mini it does really.

[Skortchio]

Groovy, that's that covered.

Now to find a battery that's a good upgrade without costing over £200!

[mini-luke]

If you don't plan to run it flat by running with the engine off and draining the battery pick the biggest good quality car battery that'll fit in the hole. I believe an 063 fits, they're about £60 for a Bosch one with a 4yr warranty.

[Skortchio]

The battery is good currently, at least for starting the car etc.

But I'm not planning on using the stereo for any length of time without the car running, no.

If I have a go at a competition and enjoy it, that's a different matter

Cheers for the help.

Don't go there - soon you'll think a £500 set of speakers are cheap!

[Skortchio]

Think I'm safe there then, the comps are only £250 ish and the sub is barely £365 rrp.

It's downhill from there, I'm warning you! Not bought the monster rockford from Ruckus yet then

They will accept.
It will be with you by the weekend.
WIN!

If you don't drive your car everyday I would strongly recommend that you get a CTek mx5 charger as well.
In fact even if you do drive it every day it won't condition the battery like the CTek will.

Using the CTek I can get my DC900's to float at a 0.1 under 13volts....get one.

[Skortchio]

I don't drive everyday, but can't hook up a charger either.

That said I don't appear to have any drain on the current bog standard battery so as long as I'm not playing long periods without running the car I should be okay, yes?

On the battery front, what is the advantage of the one you linked over say, the Pug 306/307 battery people often use in the Mini?
The CCA is higher, but the AH slightly lower which I'm guessing is the relevent part for using it as a power source?

I'd like to understand better the stats that makes it preferable, teach me wise one

[Ruckus]

These are DC batteries, they can be run down very low without damage to there function.
You run a normal battery down 4 or 5 times it will be useless. DC's can be used down to 10volts again and again without problem. And even at 10v they will have enough ampage to start your car.
Also
AGM and Gel batteries have a very low internal resistance so they can charge very quickly and discharge quickly as well. Lead acid batteries are slow in and out, not what a bigger audio system wants. It wants power when it wants it and quickly.

They also float at a higher voltage 13 ish not 12.2ish.

[Skortchio]

That makes sense, cheers fella!

[mini-luke]

Wonder if I can squeeze one in the spare wheel well...

Damn you Ruckus!!

[Ruckus]

Yes you can as they can mount on there side.
This is currently how I have mine when I run both exide's.
I was going to run with the main battery and two 6 volt units in the bottom of each rear bin. But I have an Xbox mounted in one now, so I couldn't do that. But worth a thought.

You can see the optima yellow 6v here:

It's basically just half a 12v unit
