Pairing Polk Coaxials - mistake? (n00b)

[a_caron]

Hey all, audio setups are not my forte, so please bare with my n00b conundrum.

I think I've made a mistake with my lastest coaxial speaker order.

I've got a '77 VW bay window bus that I'm adding a stereo setup in.

To keep a fairly 'stock' look up front (easiest place for thieves to see) my plan was to install a Retrosound Model 2 stereo (6-channel, 25watt rms) along with a pair of side-by-side Polk DB351's (2-way 3.5", 35w peak rms) in the original center dash speaker position, essentially keeping them hidden while directing the sound to reflect off the windshield straight back to the driver/passenger. A lot of bus owners love this speaker position.

With my particular use of the vehicle, and without going in to too many details, I won't have room for an actual sub, nor will the dash speakers do much for people all the way in the rear bench seat. My thought was to pair the front DB351's with two Polk DB691's (3-way 6x9", 100w peak rms) in the back to still get a full range of sound back there.

I figured I'd get a compact 4-channel amp installed under the dash to power everything.

My problem- in further reading, I'm starting to think my same-series Polk speakers are too mismatched peak RMS-wise to properly run on the same amp.

35w and 100w.

I figured they'd be ultra compatible coming from the same speaker series, but maybe I was wrong since they're coaxial and not component.

Have I made a big mistake by ordering the 6x9's with 100w rms? I already have the 3.5's on hand so those are staying.

Or maybe this isn't as big a problem as I think? If not, what would an appropriate amp setup be?

I'm running polk speakers as well in my s10....6.5's in the doors and 4x6's up front in dash.

I've seen a few in the doors but might have to be modified to accept them.

Peak power is something to ignore whereas rms is more important. Even if you got a 50x4 4 ch amp you should be ok. Just keep the gain low, and your speakers should be fine.

Sorry, I yeah I was referring to RMS. Both speakers have an RMS range, so I was using the highest rms value - figured 'peak' rms was appropriate but maybe that's confusing.

peak power is only a few seconds that the speaker can handle. RMS is continuous....as in all day every day even on a holiday //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
