New Speakers - Polk DB6501?

JMow · 08-25-2014, 08:49 PM

I cut up the stock speakers to make a metal basket for my tweeters. I was thinking of cardboard but thought it would be too flimsy- glad to know it would have worked though. I don't know why it's hard to cut into those stock speakers, but they did fit the DB6501 tweeters perfectly and the stock covers fit right over top. How did you end up mounting your tweeters? By the way after you get the DB6501 setup, your going to need more bass. I have a great subwoofer setup to show when I get the chance to take a pic. You use the spare tire/wheel itself as the enclosure- no fiberglassing required. Just seal the bottom with foam weatherstripping where the wheel makes contact. the rubber tire will seal the top (peace of thick plywood). Cut a hole for the woofer. Crank it down with nylon straps/ratcheting mechanisms. I threw the carpet right on top. The ratchet mechanisms propped it up so it wouldn't touch the speaker.

The cardboard tweeter mounts are flimsy, but they're just tweeters and don't move

Also, pics of your sub setup?

I got a set of Polk audio db6501 and two amps. One for the components and one for my 10 in. Sub.

When the amp is off I can hear a high frequency sound coming from the tweeters. (Only when the car is started, if it's just on the ON position there is no high frequency sound) It's really annoying.

When I disconnect the tweeters from the crossovers there's no frequency sound anymore. I just find it strange that it's making this sound even when I have both the radio and amp off. It may be worth while mentioning that my sub was getting some engine feedback so I checked my ground location and there was some paint so I scrapped it off and that solved it. (I just checked my ground for my component amp and it's also on metal with no paint)

I used a set of $10 RCA's from Amazon to connect the radio to my subwoofer amp and everything sounds good, so I don't think I can contribute the high frequency sound to cheap RCA's for my components amp. (The brand of RCA is Tsunami)

Does anyone know what is causing this and how I can fix it??

You cant be serious......... What is the volume of your "enclosure"? Does it match your subwoofers T/S Parameters?

I'm reminded by his post of all the awful DIY jobs I get coming into the shop for me to fix.
