Sundown sa 10s

[jwalec]

Hey got some few questions about the sundown sa 10 subs. What kind of box should i get for the subs? Also if i get the dual 4ohm subs and the Hifonics BRZ1700.1D, that amp will work with the subs and i load them at 1 coil correct?

2 D4's will make 1 ohm

i got 2 10" D4's in 2.5 cf box tuned to 33hz and it sound awesome. (on hifonics brz1200d)

You might, I'd do the big 3 first tho and then see if you still have a lot of voltage drop first.

just to make sure thats.

1.get bigger wires

2. ho alternator

3. and?

I got 1 kinetik hc1800 and my voltage doesn't drop below 13V

your big three is just upgrading the wires.

1. alternator to battery

2. engine to chassis or battery

3. battery to chassis

The big three is actually adding or replacing three wires under the hood. Alt to battery positive. Batt neg to chassis and Batt neg to engine block which is where your alt grounds. You basically make the circuit more efficient. There's a lot of videos and tutorials for this but each car is different so not all grounds equally effective .
