i cant find anything on this thing.
i got it with the car and i think it's imported from japan as i can't get a local radio station anywhere in oz.
plus another thing... how venerable are subwoovers to shocks?
i recently had a crash and i think the sub took quite a bit of shock from the impact but the casing is not damaged or scratched. i keep it in my trunk. wil the sub and the amp be damaged?
i'm thinking of adding more power for my audio. sub in more particular...
any idea what is best done?

RE: more power for sub
you DEFINITELY need more power, your feeding subs that want 200-600 watts way less than they can handle.... you should buy the amp i have for sale, it's an Alpine MRDM1005 1000 watts rms, with the gain down a little you'll get much better results giving them some nice clean power.
