Default suitable amp for this subwoofer?

my electronics teacher just gave me a non working subwoofer today, an infinity BU-120. it looks to be not bad. the amp was blown so i tore it out, and covered the back hole with a piece of plexi and sealed it with some bathroom sealer i had laying around. right now im looking to build an amp but i dont know what i should make. ideas?


i cant find too much info on the sub but its 12" and it was originally 150 watts.
from infinity: http://www.infinitysystems.com/homea...&Submit=Submit

sorry if this should be in a different forum, ill go to the appropriate amp forum when i get an idea of what i need. im pretty new at this diy audio stuff, so dont overfill me with jargon

Get an amplifier with an RMS rating close to the RMS rating of the driver in question. Consider excursion also [winisd pro from linearteam.dk]

Plate amps are quite value for money.

Cheers!

Default Sub-Amps

Check out my website at www.apexjr.com
under the amplifier section and I would suggest
either the Apex "Junior" or the AudioFile VRS 1205
to use with the Infinity driver...

I'll suggest to look at plate amps from PartsExpress also.
