There's more flexability in your wiring options, allowing for a more range of ohm loads. You want to shoot for the lowest ohm load your amp can handle, 1 ohm would be easiest + best to get since you can push more power through it.
Get an amp that has enough RMS output to match or be close to the speaker's RMS ratings. Cadence A7+HC
1400W @ 1 ohm, 0.005 THD, some 95% efficency. Really really nice amplifier, I know because I have one. Cadence's other amps are REALLY nice, but draw a lot of electricity because they arn't as efficent. Acoustic Visions
- If you have the cash, the adire drivers's quality + volume will knock your socks off. I have the bhrama's older brother, the tumult. (made for home use & slightly larger boxes) ::RESONANT ENGINEERING::
- Great drivers, never messed with them in person but many sub enthusiasts I hang around with say they are amazing. XXX is aparrently best for SQ.
Remember: Wattage does not equal loudness.
