im helping a friend build an economical stereo in his truck. he wants a pair of 10's, a bass amp, and 4 ch for the fronts. the budget is about 600-700 for subs and amps. were more interested in sq than spl. he already has some polk db coaxes up front that are great for the price. weve looked at pg octane amps, us amps xtreme series, and memphis pr amps. subs weve looked at are tc 1000's, idq's and mmats 2.0's or 2.5's. we have about 2 cubes available for the box. these are all similar in price and within reach. any suggestions or oppinions on these?
Well pretty much everything you listed there is good equipment, but USA definitely wins for amps. As for subs I can't say since I don't have experience with any of those or know anyone who runs them.
