[69halfton]

k so,
in all the confusion, turns out i have 6 1/2 inch pioneers instead of 4x4s, but i was right about the power rating(160 watts max).
while taking apart the old system, i found the old amp, its a two channel amp, 30watts each. which conviently happens to be the running power on these 6 1/2s.
If i go and buy my 6x9s, and buy a four channel amp,
could I: make then new four channel amp "bridged" (is that what you call it?) into three, with the bridged channel running the amp, and then run the other old amp so that it only powers the 6 1/2 inch 2 ways?

question 2: is there any way to test to see if this old amp is any good?

question three: if i were to buy an amp, bridge is, run the sub, and both 6 1/2 speakers...would the 6 1/2 speakers be drowned out do you think?
