I been having trouble with the tweeters in my Polyplaner's. They don't seem to get very loud. not very efficient .

I also need to up grade . I already have the power and subs .JUST need some volume.
someone told me to try the alpine 6 1/2 marine ?. The kickers looked pretty good also.

I guess all are made in japan??

Look at kicker, did a whole boat in kicker it was awesome, or rockford just came out with some new stuff with dual tweeters.

Thanks for all of the advice. Jimmy baja that looks crazy! and yes I am going to have a spacer only have 1.5 inc. of depth. I am wanting marine speakers because my cockpit cover will not cover these When I am pulling down the road. I have all my good speakers down in the cockpit. (6*9- 6.5- 10sub- horn tweeters)

Has any one hear of Image Dynamics sub woofers. I am told they are a top of the line sub.

Infinity makes a marine version of the Kappas ..

I had a set of 6.5" alpine speakers in my old boat that sounded pretty good. Not the best but good for the price ($120/pair)

I would recommend that you use a crossover (active or passive) to filter out the low end otherwise you'll get distortion at high volumes.

I will agree that Image Dynamics makes a great sub. I have been a dealer of theirs for ten years. I sell those as well as numberous brands. Call 813-882-8477 and mention OSO for adeal.

I did a system this past fall w/ Image Dynamics subs (a bed cut in a 1985 Chevy), Fosgate amps. I am not a dealer for either, customer bought the stuff and I built the system... THEY KILL!!
