another selfish question about my boat...
 
I have 6 cabin 7.7 JL speakers and I would like each of them to see 200+ wrms each. What is the best way (amplifier wise) this could be accomplished?

ie - JL HD750/1 into three speakers (250wrms each) x 2

(2) m600/6's bridged ...IMO

I agree. Dual M600/6's bridged. With a realistic 12.6 V supply you would be getting a true 200 watts to each of six speakers. And in the highpass mode that is about the power handling limit. An HD600/4 on four cockpit 7.7s with an XD400/2 on two bow 7.7s (or the marine equivalent model) will do the same. The strictly regulated HD600/4 does not lose power as the voltage drops and has dual power supplies making it a beast.

Thanks guys!

For a single amp option, Wet Sounds SD-6. 1 amp, 6 chnls 185W rms x 6.

Very true and a good choice.

One more then....
best amp for 2 Bullet hollow point 770 HP's?

That's easy. For a single pair, a bridged JL Audio XD400/4 (same as a M400/4) will give you a realistic (as tested) 200 watts per channel even with a 12.6V supply or 280 watts X 2 with a 14.4V supply (which is unlikely). That's about the top end limit on a 7.7" HLCD. Have heard this same amp on many Rev8s and they rocked! Also heard the XD800/8 bridged into four channels on two pair of Rev8s. Very imprerssive.

Tougher question then - I currently have a ARC audio KS300.2 rated at 180w (independantly tested 167w x 2 @4 ohm @ 12.5v, 222w x 2 @ 4 Ω @ 14.5v)
Would the difference be noticable (worth it)trading out the ARC for the JL?

Okay, so going from 167 watts to 200 watts is less than 1 dB difference and you would not hear that difference.
