wireing confirmation

drk hitman · 20th August 2012, 02:40 AM

OK so I bought 2 of these:
Rockford Fosgate R2SD4-12 (R2SD412) 12" Prime Stage 2 Subwoofer

And running this amp:
Nitro BMW-482 (BMW482) 2-Channel Amplifier with Bass Remote

Running it wired for 2 ohm into 2 channels. It does not thump at all and sounds like crap. It bumped Harder with the single sub. Seriously my wife's single 10 pioneer slams compared to this.
No I know I need a different amp and plan to get one. Soon as I find a good one.

So can I run this:
Rockford Fosgate® - Woofer WiringWizard

4 Ohm bridged to provide 300w to both subs?

1 of your subs may be out of phase.. Try switching the positive and negative speaker wires around for 1 sub only and see if that helps

Just checked. wires on both subs are wired for 2 ohm. Both subs sound the same.
They produce bass but just dont produce much. I would think at 150w each it would rattle the window pretty good.

Anyone know if I can run this in series at 4 ohm bridged?
That should put 300w to both subs. if I understand it correctly.
