Levi Leipheimer (RadioShack) sewed up his overall victory in the inaugural USA Pro Cycling Challenge on Sunday as Daniel Oss (Liquigas-Cannondale) won the final stage before a packed house in downtown Denver.

The 73.8-mile sixth stage from Golden to the Mile High City looped to the north and then back through downtown Golden, up Lookout Mountain, past Buffalo Bill’s grave, then back around through Golden once more before heading to downtown Denver for a spectator-lined circuit around the Colorado State Capitol and Civic Center Park.

A huge break early on drew out way too much horsepower — including race leader Leipheimer, best young rider Tejay Van Garderen (HTC-Highroad), Tom Danielson (Garmin-Cervélo) and Tour de France champion Cadel Evans (BMC Racing Team) — and it was brought back, giving a smaller group a chance to get away.

Oscar Sevilla (Gobernacion), Javier Megias (Team Type 1), Lachlan Norris (HTC-Highroad) and Matt Cooke (Exergy) had an advantage of more than two minutes as they led the USAPCC into Denver for the first of six circuits. Sevilla was best-placed in the break, sitting 19th at 3:16.

Liquigas-Cannondale took charge of the chase, with an assist from RadioShack and Garmin. But the gap remained pegged at two minutes as hares and hounds raced around the Capitol and past the original Quiznos store, which opened for business at 1275 Grant Street in 1981.

With four laps to go the gap was down to 1:45 and falling as the peloton drove along at more than 30 mph. Evans, seventh overall at 1:18, had a mechanical and was forced to chase back on with the help of his team. Two-time Giro d’Italia champ Ivan Basso, meanwhile, was on the front and cranking out the watts on behalf of Liquigas teammate Elia Viviani, already the winner of two USAPCC stages.

A lap later the chase was just 25 seconds behind and Megias shot away up the left side of the road, followed by Norris. as for Cooke and Sevilla, they were soon back in the bunch.

With two laps to go Megias was clinging to 25 seconds’ advantage as Norris was pegged in no-man’s land with UnitedHealthcare-Maxxis leading the bunch for sprinter Robert Förster.

The ruthless chase soon enveloped Norris and only Megias remained out front. But not for long — as the peloton prepared for the bell lap, it was gruppo compatto.

Then HTC’s Hayden Roulston attacked with just over five miles to go. the Kiwi pursuiter led the way into the bell lap, chased and eventually joined by Oscar Alvarez (Gobernacion de Antioquia-Indeportes Antiquia) and Ryan Roth (Spidertech-C10).

The trio quickly took 12 seconds over the peloton — Andy Schleck (Leopard-Trek) wearing the orange jersey of the most aggressive rider, tried and failed to bridge — but with a mile to race the bunch was closing in fast.

Roth attacked the break as the catch came, but didn’t seem committed — he kept looking over his shoulder, and soon was pulled back. Then Van Garderen tried an acceleration and Leipheimer was on him straight away.

Headed for the line Liquigas was back at the front, with Oss leading out Viviani as he had twice before — but the thoroughbred double stage winner generously awarded the victory to his workhorse, settling for second ahead of Fred Rodriguez (Exergy).

I need a total of 260 RMS Watts for my speakers and am looking to by like a 400 watt amp. will over powering the speakers ruin or hurt them? thanks.

Yes it can, when you get a sub or amp, always match the RMS power to each other.

Here is an example of what it should look like,

the amp,
1000W 2-Channel A/B Class Amplifier
2-Channel Operation
RMS Power Range : 2×500 Watts

So get subs that do not have more then a 500watt RMS power rating, in other words, like this one,
Alpine
Alpine SWR-1242D – Alpine 12" Type R 1500W Dual 4 Ohm Subwoofer
Power handling: 50-500 watts RMS

Notice how it says its a 1500W sub? but the RMS is 500RMS?
That's because Root mean Square is a formula that provides a reasonably accurate means of measuring and comparing continues AC power.
The use of this measure is preferred when matching system components, like amps and subs.

Max power, the amount of power a speaker is estimated to handle during a brief high-intensity musical burst.
Since this can vary with both frequency and amplitude, it is a much less accurate way to judge speaker durability and performance then RMS.
keep this is mind when choosing subs and amps, and youll be fine.

So find an amp with the same number of channels as speakers you have that runs 250RMS to each channel.

anything over this will blow the speakers.

that 400watt amp's rating is probably inflated like most amp advertisements. see if it is 400watts @1ohm or 4ohm. if it is 400watts rms@1ohm, than it's really around 100watts rms @4ohm. if it's rate @4ohm than yes you have too much power and you should turn the input gain all the way down and slowly turn it up to match the speakers peak volume. if you hear distortion at your prefered max volume setting than the gain is up too high. just turn it down until the speakers stop distorting.

there is really no such thing as an amp that has too much power. all amps have an input gain control that you can adjust from 0-max.
