I'm going to try my hand at building a DIY sub. My plan is to make a Tempest in an Alignment setup. I don't want to spend a lot on an amp so I am thinking about using the Parts Express #300-792 156-watt amp. Would this amp be suitable for use with this kind of configuration? I'll get the 250-watt if I have to but I'd rather save a few bucks if I can (to use toward another Tempest later on ).
