A capacitor will solve your problem with your headlights dimming. Basically its the same as the battery but is designed to release charge much faster, and is perfect for huge drains of power like when bass drains power.

Make sure that your earth connections are big enough also. Often if the earth for the amp isnt large enough and isnt grounded properly you with cause an unnecessary drain on your battery. Unless you're pulling in excess of 800w RMS then your headlights shouldnt dim unless your current battery is shit, or your wiring isnt up to scratch. Replace your current battery with a deep cycle unit - Odyssey or the like. Use 8 gauge earth wiring on your amps for anything under 800wrms... 4 gauge for anything above that...

Installing a 2nd battery should be your last resort, and you would want to upgrade your alternator to go with it or you're wasting your time really. For cheaper you could make your current system run properly.. Your car uses bugger all driving along anyway, so if you're worried about being able to sit there for a while and play PS3, you're not going to get much benefit from having a SECOND battery... beause the first battery will be almost fully charged when you stop anyway..

Seeing as you already got some cable from work, make up some cable to go from your battery to the chassis. Something like this.

That is 2 x 35mm2 cables. Very much over kill for what I have, but it does the trick :P

      Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P
