The Aluminums are speced for 500 RMS so he should be fine although I would suggest the JL 1000/1, yeah big suprise there right?
Boston has 3 levels of components, we carry the RC, the Pro and the Z. The RCs should get a good 75 watts rms we have several amps for that and the Pros and Zs should have either the JL 300/2 or the alpine MRVF540 bridged running them. YOu could aslo use the kicker kx600.4 bridged for the most raw power to the components but I would stick with the JL or Alpine.
I will need to know the exact components if you need any help or advice on the proper amplifier for them.
