those spl subs are no where near top of the line anymore. I run comp's, and trust me not many pioneer. Also im talking about amps, not subs. There amps are garbage unless you spend the big bucks, so trying to buy low end chinease pioneer is dumb imho.

the mb quart will be a better buy and the aq and cadence are korean made and much better quality.

I can also sell him a orion hcca225 which will blow them away also. or an old school cadence q-400 for 40 bucks shipped made in the usa.

also you can call steve mantz at zed audio, makerds of some of the best sq equipment, us acoustics etc. He has overstock of some boss audio equipment he made for boss that boss decided it didnt want to pay for and went cheap back in 1999. its the same exact amp as the us acoustic usx-4065

65watts but rated at 12vs and not 14 like amps nowadays. and very low distortion .01.
