I just got the Sony CDX-H905IP deck, Polk Audio 6.5 Coaxials, Polk Audio 6x9's, and a 4 channel Sony amp. I was wondering if anyone has a similar setup. If you do, are you happy with it or should I get another Sony 4 channel amp and bridge it with (2) 8" subs? Please help, thanks.

Its kinda relative to how you want it to sound and how ya install it. If you want to hear it when the boat is running adding the 8's wont help. That setup should give ya decent sound as long as its installed correct.

Yah, Id say it also depends how many watts the 4 channel is. That CD player will run the 6.5s and even the 6x9s at a decent volume. Any amp will make it sounds better turned up. As far as the 8s go, depends on the watts. I have a sony that ran 4 6x9s in the party barge and it sounds fine. Installed an amp for the highs and an amp for a 12. Sounds great even loud now.

The amp has a 600W max output. I would get the same amp and bridge it and get 2 Polk Audio 8" subs

What boat are we dealing with here ? If its the one in your avatar, forget about good sound when your running across the lake (to much noise from wind and headers). The next thing is speaker placement, if you get somewhere where there not aimed at your feet they will sound better and louder. I personally wouldnt waist the time and money with 8"s, if you going to add some bass to it go with 10"s (up under the bow) and a decent class D mono block amp, I'm sure Sony has an amp to do this if you want to keep it all Sony. The reason for the mono block is because it will have more power, generate less heat, and be more reliable then bridging the 4 ch for bass.
My recommendation to start would be to try running the highs (6.5"s and 6x9s) off the deck (mount the as high and as exposed as possible). Then use a pair of 10's under the bow with an amp for bass (even if you use the one you have). I wouldnt use an amp for the highs unless you really need it, it will be more drain on the batt and you will get less play time.
Another option is to run the 6.5"s and 6x9"s off the 4 ch amps front channels and bridge the rear channels to a pair of 8 ohm woofers (or a good single 10", 4 ohm) up under the bow. This will also keep your current drain fairly low (good play time), and should sound good.

Thanks for your input. It is for a '78 Challenger (loud as hell!). I will run a second battery and I'll have a battery selector switch setup so I'll have plenty of play time :) Im not really worried about having it so loud that I can listen to it when I run, because to be honest with you as much as I love to hear music bumping, I love the sound of the 454 EVEN MORE! I got it more for the time when you just post up and chill somewhere. I may just have to do a quick instal with the amp to the 6.5s and 6x9s to see how it sounds and go from there. Thanks again for your advice.

i have two 200 watt 7.5s and two 500 watt 12s. all powered to the fullest and i can barely hear it when i am under throttle heading up or down the river. but once we stop everyone knows where the party is.

Nice. I ended up getting 2 6.5 Polk Audio, 2 6x9 Polk Audio, 2 8" subs Polk Audio, 2 600w Sony amps, and a Sony deck (AM/FM, CD, iPod). My interior is getting redone right now and theyre also making a custom enclosure for everything and hooking it all up. Can't wait to get out there!!
