FreeZzy Posted November 23, 2013 Author Report Share Posted November 23, 2013 Hello, finally i'll put an Speaker to RCA adapter, optical is complicate and can make electrical problem. tell me if I'm wrong for the installation of power cable? -1/0 from alternator positiv to positiv terminal under the hood (battery positiv extension) -1/0 from positiv terminal under the hood with 1 300A fuse to battery positiv in the trunk (again with 300A fuse?) -1/0 from positiv battery in the trunk with 1 300A fuse to second battery. -1/0 from negativ first battery to chassis -1/0 from negativ second battery to chassis. this is correct ? And which wire size i need ? and how to wire 2x T2D215 (dual 2ohm per sub) if i want use all terminal of amplifier to have 2ohm or 1ohm? or is better to ignore one terminal ?

I'd also include a 1/0 wire from your alternator casing to your chassis. What wire for your subwoofer? Most use 8ga, but it depends on how much power you're running. The extra terminals on the amplifier are for easier wiring configurations. You can use the extra terminal if you'd like but it won't hurt anything if your don't (assuming your overall current draw through the speaker wire matches the wire size). With two Dual-2ohm coils, you can wire the following options: Parallel all coils for a 0.5ohm load. Series-parallel for a 2ohm load. Series-series for an 8ohm load.

FreeZzy Posted November 25, 2013 Author Report Share Posted November 25, 2013 Thank you for your answer. For power is RF T2500 with 2 RF T2D215 ( total 2500 rms ) But how to connect 2 subs on 2 amplifier terminal to have 2ohm load ? i never do that. I always connect the subwoofers together, and for the size of cable I want to take i can't put 2 big wire in 1 terminal of subwoofer so I prefer use all terminal of the amplifier ( again sorry for bad english ) Link to comment Share on other sites More sharing options...

So take the two +'s and two -'s and run them straight to the amp rather then trying to combine them into one wire. If that makes sense.

Wicks Posted November 25, 2013 Report Share Posted November 25, 2013 This image may be more clear (disregard the speaker ohm ratings): See how the four wires route to the amplifier. All four can be connected to the amp rather then combined to fit in a smaller terminal block.

FreeZzy Posted November 25, 2013 Author Report Share Posted November 25, 2013 I think I understand. I need to connect 1 positiv terminal to 1 negativ of each sub and 2 terminal of each sub directly on amplifier right? If i do that I have 2ohm load per subs right?

FreeZzy Posted November 25, 2013 Author Report Share Posted November 25, 2013 I give you a picture, and tell me if it's good how i do? EDIT: You think I need to put a 1/0 ga wire from alternator to positiv terminal under the hood and then 1/0 ga wire directly from this terminal to positiv of battery in the trunk?Or i can just put a 1/0 ga wire from alternator directly to battery in the trunk?

Wicks Posted November 29, 2013 Report Share Posted November 29, 2013 Yes that looks correct. Sure, you could wire straight from the alternator to the trunk and not route to the under hood terminal, but the cable should still be fused.

FreeZzy Posted November 29, 2013 Author Report Share Posted November 29, 2013 Thank you again Fused 1/0gauge wire right? Link to comment Share on other sites More sharing options...
FreeZzy Posted November 29, 2013 Author Report Share Posted November 29, 2013 If I wire subs like that, each subs are at 2ohm right? And if I put all this 4 wire in amplifier, it's loaded at 1ohm or 2ohm or another? Sorry for bad English I try to do my better ^^ Link to comment Share on other sites More sharing options...
