Amp Guidance

Hello all,

I've just purchased a pair of Shok Industries Triton 12 inch subwoofers. While I'm fairly adept at installing basic stereo systems I've not had a great deal of experience with matching dual voice coil woofers with amps and the most effective way to wire them.

The sub specs are as follows:

The Triton 12″ features a 3 inch dual 4 ohm voice coil rated at 500 watts RMS and a 3.4KG magnet assembly.
Specifications
(VCs in series)
re-7.5ohm
fs-30hz
qts-.50
qes-.55
qms-4.87
vas-1.1cu ft
sens-84.4dB SPL
mms-218g
Mounting Depth : 162mm
Mounting Diameter : 280mm

So the real question is, which amplifier setup will suit these the best considering the power requirements? Will I need a capacitor? I'm currently running only 4 gauge wire. Will this be thick enough? this was in place from a previous install by the previous owner. These will be fitted to the boot of a VL Commodore.

Cheers

setup subs in series, 8ohms per sub x2 will see 4 ohm load at the amplifier. Ideally you want a mono amp capable of 4ohm load at 1000wrms, should be an easy find.

this diagram will help you:

I thought subs like these were meant to be wired in parallel to reduce the impedance, hence providing more power?

Which would mean a requirement for 2000wrms?

Again perhaps I'm naive but I was also of the view that a mono was designed to be wired for a single channel which would mean in parallel that I would require an additional amp?

Sorry about the simple questions!

Cheers

if you want spl and sound quality is not your goal, then you go parallel down to 1ohm with these subs. you would then need a 1ohm stable amp that will push 1000wrms or there abouts.

I am not familiar with these subs, but if they are more SPL design then the above may be better option for you if chasing outright power.
