2nd Amp

[SWE11L]

I want to wire up a second amp to run my subs, does the proper way to wire up the amp include running a new power cable from the battery or can I run one from my existing amp to the new one? Same question in regards to rem cable. Cheers.

Remote cable you can daisy chain.

Power depends on the thickness of the cable and also the amplifiers you plan to run, what size is your cable and what amplifiers are you planning to run?

the power cable i have had run is around 5mm thick. Ill put links to the 2 amps I have. I dont know much about stereos but I do know I can get a monblock to run the subs but I have this spare 4 channel so I'm just planning on using that if possible. The mtx is what I have hooked up atm, the alpine is a gift from a mate.

5mm thick copper? There should be a measurement in gauge on the wire, if yours is 5mm in total diameter it is way too small. Check out the brand / size of your power cable before doing anything else

says 8 gauge

Too small, you'll need to invest in a thicker power cable, which is likely to mean a bigger fuse/fuse holder too. Then you will need some more cable for earths and a distribution block for the power.

I run 2 gauge from bat to distribution block and then 4 gauge to both my amps pulling 1300 watt's RMS and I've never had a problem, Rem cable you can piggy back

And run a new earth to the chasis or can it be 'piggybacked'~'daisychained'?

 

[sweefu]

No, I'd add another cable to the same earth, or add another earth, or buy 2 distribution blocks, use 1 for power 1 got earth.

Yes to all above there are power limits & you need more to run both. I would just run another cable & main fuse if your happy with the way it's currently set up, try this link #16 http://forums.justcommodores.com.au/car-audio/190941-need-advice-system-600-700-budget.html#post2156586 I posted awhile back in regards to running your cable etc
