im thinking about getting this amp, I know its a current hog, but other than that is it a decent amp?

my friend had 18's on his focus and with lowering springs it rubbed pretty bad. stock suspension not to bad. on bags it didnt rub unless it was dropped
you can do subs, box wiring and amp for about 1500 that will slam. now if you need head unit and speakers it can get more pricey. you should have no problem putting a nice complete system together for around 2 grand
