Ok so I plan on running an amp for the speakers then getting an additional amp for a possible stealth box. Ok. So from what I've been reading I would need a 4 gauge running form the battery. But from the distribution block.....can I run an 8 gauge?

Also will using preouts from one sub to the other sound good enough?

 

You can only use 4 awg if your combined wattage is below 500watts. Otherwise you must use larger cable for power AND ground. It's ok to use smaller cable for a short run from a distribution block to each amp, but it must be capable of handling the current draw.

Also, check to see if each amp is internally fused. If they are not, then you must add a fuse at each amp, or at the distribution block. You must also use a fuse at the battery.

I don't understant the question about preouts, so I guess you'll need to describe it better.

 

Ok from what I'm understanding. I have a750w amp and a 240 watt amp. So I would need a thicker cable to run from the battery to a distributor. And from the distributor I could run say an 8 to the 240watt and a 4 to the 750? or would I need a bigger one for the 750 watt amp.

Preouts

I have a preout on one amp (speaker) can i put that preout to input (by RCA) to my sub amp?

 

You are gonna need a capacitor too or lights will dim

 

Waste, it's shown these don't tend to help much.
Best bet is a second battery with an isolator. I'm unsure as to the stock output rating of the 2011 alternator, but if past models are any indication, the alternator likely won't be able to handle this averaged draw without being rebuilt or replaced.

My entire add-ons are <600watts, likely actually utilizing far below 450 of that on average, and I can't keep a battery for more than a year or so without it needing to be replaced. One of these days I'll get my own rebuilt.

 

Danget...never knew adding two amps was such a pain. Maybe I'll just keep stock subs and hope the new polks with amp does it for me.

 

Itīs something in the realm of 85amps for the 05-09īs. Iīd hit up google for the output of the 11īs (or maybe someone can chime in here), likely higher, but I still doubt itīd be able to keep up.

If you can find someone local itīs usually not very expensive to have your existing one rebuilt to output quite a bit more.

 

yea capacitors arent very helpful. if you want to get a capicitor, i recommend on getting a higher power battery first. if lights still dim than upgrade the alternator. then you can do the capacitor.

im runnin a Polk Audio 800w amp, with a Polk audio DXI 12" thats gettin 650w rms. and my lights dim. im gunna be gettin a higher powerd battery soon.

 

Just letting you know you picture distracts me from reading. I like it

 

how bout post the model amps you have
