Considering upgrading my Amps.

[Radioflyer97 10+ year member]

I'm currently running a pair of Alpine MRP F250 amps to a set of 4 Alpine SPX 177r comp speakers. The amps are bridged at 100 Watts x 2 output. I'm looking at the slightly larger (and reasonably priced since last year) MRP F450. It's only 2 inches wider than my current amps and would fit in the same space in my Amp rack. It would also accept the same KOL 8 power/ground wires i'm using. (my current setup has the amps as the weakest link)

Ideally, the MRP F450 model would supply 200 Watts per channel. The SPX 177r speakers have a peak power handling of 300watts and I feel the Woofers are being significantly underpowered.

Thoughts?

If I'm reading right, their RMS is 75W, which is A LOT under 200W. You are definitely not underpowering them. Next time, don't worry about peak power, just RMS.

True, but then why is the peak power so far off of the RMS?
