I don't cheap subframs would be the right choice. I think you are looking for more popular. Most members here do have DSE, AM, and also Heidts. I personally went the stock sub route for now because it was the best value for PT that was in my budget. And unless you are going all out at track events then a stock sub will be fine with some good upgrades. Well just my .02 and if I were you just search this site for older threads on this topic you will find good reviews on all of the subs it really just come down to what you want.
