(2) Alpine Type S 12" 900w i believe 150 rms per voice coil 4 ohm
off of
(2) Kicker ZX350.2 both in bridged mode

i don't wanna run two power cables from the battery, whats the easiest way of doing this without having to jump my car every 5 minutes

Subs
Amps

please help

thanksss

 

Run 1 large power wire from the battery to a distribution block mounted near your amps, then smaller wire from the dist. block to each amp. Here's a link to an inexpensive, yet good quality distribution block;

those amps are going to be working real hard to power those subs...

 

how so? two of those would be 1800 watts and both amps put out 2000 or if i didnt bridge them and just run each channel to a VC?

idk it seems like it would work fine each channel is 175 rms and each VC is 150

 

thank you!
didnt know i could do that, would a 4 gauge main power wire and two 8 gauge going to the amp be ok?
and could i just daisy chain the grounds?

 

How is the amp putting out 2000 watts?

The amp bridged is going to be putting out 120W RMS to a voice coil that is 150W. Each channel is putting out 60W RMS @ 4ohms and 90 @ 2 ohms.

I have the same amp, and it overheated a few times pushing a subwoofer rated at 200W RMS at 4ohms, and 2 speakers up front.

 

Yes, 4ga from batt. to dist.blk., then 8ga from the dist.blk. to each amp. You'd either run separate grounds from each amp to the same ground point, or get another of those distribution blocks (since they cost so little) and wire it the same way (ground point 4ga to dist.blk., then 8ga to each amp).

As for the power of those amps, what TheQuietThings stated is correct, you're apparently getting a bit confused due to both RMS vs "max" output ratings, and the impedance the subs will present to the amps. You can use those amps and they'll drive the subs ok, but you'll need the gains set correctly to avoid distortion and won't be getting all the output the subs are capable of. It'll be ok, but it's less than optimal, you'd be better off with amps that could run bridged 2-Ohm loads, or a single more powerful amp, whether it's a 2-ch or mono model.

Don't pay attention to "max" ratings, look for "RMS", and realize that with most amps, the 4-Ohm output is often only 50-70% of the 2-Ohm RMS spec. Also many amps (like yours) can only handle a 4-Ohm bridged load, they'll have problems if your try to run them 2-Ohm bridged, which is what you'd get if you parallel wire the 4-Ohm VCs on one of your subs.

 

make sure your box is divided and use a dist. block, also you should be able to parallel the rca from one amp to another

 

yeah i currently have one pushing two kicker comps (12 in) and its working fine
but i understand what you mean

 

thanks for clearing that up, im kinda new at this currently my kickers (comp 12) are doing ok i feel its not as good as i want
