Kenwood HU, Blow my system?

[Markjr]

I am planning on buying this Kenwood head-unit. I will eventually get kenwood speakers but in the meantime will I blow my stock speakers by playing music loud through the new head-unit? When I say loud I mean pretty loud but not ear piercing if you know what I mean.
Kenwood - 50W x 4 MOSFET Apple® iPod®-Ready CD Deck with Built-in HD Radio - KDC-HD548U

In case the link didnt work the specs are
Max Watt 50W x4
RMS 22W x4
If anyone know the specs on stock 3rd gen SR5 speakers and HU please share, Thanks!

Max Wattage means NOTHING, just ignore anything that says Max watts.

You should definitely notice an increase in sound quality when upgrading from the stock HU.

If your music sounds distorted, the speakers could blow, if it's not distorted, you're fine. Just be careful with your volume.
