norcal colby Posted November 28, 2010 Report Share Posted November 28, 2010 Hey guys, new to the forum and wanted to start by asking a quick question. Ive done all the calculations and im pretty sure my set up will work, but i just wanted to run it by some more people. I will be going with 2 10w3v3 JL subs with an MTX JH1200 amp. the amp will give me 800watts at 2ohms rms. i want to know if a 4guage input will be enough. it accepts 1/0 guage but i already have some 4guage laying around to use. I have a speaker amp that Ill be giving 4guage already so I will go 1/0 guage to a distributer block to 4guage. Do you think that the amp will require more??

If its OFC Copper wire, 4gauge should handle 150amps of current. As long as the amps draw is less than that you should be ok. I don't think an 800 watt amp would take that much.

Guest Posted November 28, 2010 Report Share Posted November 28, 2010 (edited) just use 1/0 gauge. i dont know why a 1200rms amp needs 1/0 gauge (might be cause its so fucking inefficient, i dont know) but i wouldnt take the risk. i have a feeling you will get mixed opinions on this. edit: damn double ninja'd.

SQMonte Posted November 29, 2010 Report Share Posted November 29, 2010 (edited) If there's no possibility of you ever wiring the amp down to 1 ohm ever, then you'll be fine using 4ga. But if there's any possibility that you'd at some point want to get the max power out of that amp @ 1 ohm then you might as well bite the bullet and use the largest wire the amp will accept.

norcal colby Posted December 5, 2010 Author Report Share Posted December 5, 2010 sorry for not replying guys, i got busy. im using two 4ohm subs single coil so the load will be 2ohm. and the rms from 2ohm is 800w. i asked MTX themselves and they said that the max amp draw is around 80amps. so i figure 4AWG should be fine. thanks for the insight i think the 1/0 guage is just for looks or for those who want to go into 1ohm.

Loudcivic Posted December 5, 2010 Report Share Posted December 5, 2010 its not for looks lol. they have the 1/0 gauge inputs for a reason Quote 2015 silverado crew cab nothing atm but soon... Link to comment Share on other sites More sharing options...
norcal colby Posted December 6, 2010 Author Report Share Posted December 6, 2010 its not for looks lol. they have the 1/0 gauge inputs for a reason alright alright, ill take your word for it I just dont like ponying up haha. considering the fact that im getting a $500+ amp for only 250 I guess I can dish out a bit extra for some 1/0 guage wire. im recieving a Kinetik 2400 battery too (practically new from my brother for free). I just need to find the best solution for wiring it all up. my speaker amp takes 8 guage.. (will probally use 4guage cut at ends to fit...) so ill probally end up just running the wires straight from the battery to the amps instead of using a distributer block.

Why not run less of the expensive stuff and use a distributor block to branch into the cheaper wire? I mean $5-$50 for a distributor is not much. It will make the system a lot better and it won't be ghetto like you plan on doing it. If it's worth doing, it's worth doing RIGHT http://picclick.com/Amazon/Electronics-Computers-Photo/Accessories-Supplies/Car-Electronics-Accessories/Amplifier-Installation/Power-Distribution-Components/ Quote i suck men dry...email me for details Link to comment Share on other sites More sharing options...
