Would RF T400-4 get enough power for Boston Pro 60’s?

[quick01]

I already have the Rockford Fosgate T400-4 installed in my 05' Ford Focus. RF lists the amp at 60Wx4, but the birth sheet says 75Wx4 @4 ohms. I've read the Pro 60's sound better with a lot of power. How would the 60's sound mated to that amp?

Im sure that would do,but to really wake them up Id run at least twice that.Ive read about people running 250 per side to them without a problem.

One thing Ive learned about car audio is that there is no such a thing as too much power.You just need to know how to set it up.

I had the T400-4 and thought it was a nice amp. Try it out, if you don't feel it's enough juice why not bridge it? It will give you a little more than 200 watts RMS per side.

remember the pros are 3ohm, i think that 75x4 is 2ohms correct?

That is subjective, luckily there is a simple answer plug them in and see.

RF Performance Verification Certificate states:

75 x 4 @ 4 Ohms

125 x 4 @ 2 Ohms

250 x 2 @ 4 Ohms

How accurate are these "Birth Sheets" anyway?

I want to know before I order them.

I think the amp will produce those #'s.

Ok....so that would means approx. 100W@3 ohms to the mids and 75W@4 ohms to the tweeters. Right?

The tweets don't drop to 3 ohms also, do they?

try bridge it!

try bridge it!

*CAUTION!* (noob question)

Bridge and just amp the mid's or both? Please explain.

my pro's definitly needed more power than that.

running gains set at 300wrms per side using -3db 1000hz test tone...

yea i got an orion 8002 on mine that does around 300 per side

i think it will be 6 in a row, or at least im hoping

Sorry, my mistake! Thought you were a "Bamer". Your user threw me off. Let's hope Cox has a good game, sure would help!

Ok...to bridge the Pro60's I should use the provided "Signal Bridge" connector and wire them "Crossover - Single Input" as described in the sparse manual? Right?
