Too much power??
 

Hello I've been have a nightmare with my boat stereo..... I originally had 1 JL audio 360/4 power 4 hertz 6.5, but it wasn't loud enough... So then I added a kicked 10.5 sub with its own amp... Then I got greedy and wanted more.... My local stereo shop talked me I to buying a second JL audio 360/4 and bridging the 2 amps to run the 4 speakers that I upgraded to the hertz HCX 165... Since doing so two sets of the speakers have fried... So I bought morel tempo coax 6x9's and right after install one set started smoking ..... Ive heard different things from 3 diff stereo shops ...... i need help this system is draining my bank and still isn't reliable ......
Thanks

Doubling the power to the same 4 speakers usually doesn't net a whole lot more volume. Since you already have the power, adding additional speakers is the way to get it louder.

you need additional speakers. In your case maybe going with larger drivers...

Larger drivers are also a lot more efficient (generally), playing louder on less power. Look for efficient drivers. If you look at the sensitivity of a 6.5" driver vs a 8" driver of the same series the 8" will be more sensitive.

I suggest you stop going to car audio shops for advise and try doing some research on what type of system will let you achieve your goals.

This guy needs some pro audio speakers.
Cheap, loud, take power - The End.

So I can see my best bet is to add more speakers .... Bridging the amp really isn't gaining me much?? I'd love to add speakers. But the boat really doesn't allow too many options for speaker mounting....
All advise is much appreciated

You need a car audio friend real fast and unfortunately I'm not that guy ...
Shops are good places to chat with knowledgeable people but at the same time, it sounds like this shop is just letting you buy anything off their rack and letting you blow it up ... which doesn't sound right to me.

You're buying good pieces of equipment, I don't know if that's because you're looking for real SQ or you're just trying to buy "the best" ...
You need to do a little more research all around ...

At the very basic level, even if you buy "the best" and it's a 70 or 100 watt (rms) system, it's not going to be that much better than say an Alpine set that gets you 150 watts (rms) when all you're talking about is being LOUD.
That's why I actually said (and meant) pro audio ... the world of Selenium, Crescendo, etc ... since I would think in a boat you need to hear vocals over the water, as opposed to mid-bass, I don't know ...

You need to stop this bridging bs immediately ... you have good amps, use them direct to the speakers, stop making super amps that you're blowing your stuff up with.

If a car audio shop wants your business, most shops will spend a little time talking to you about your goals and the problems you will run into.
Other shops have you stand in line, take a number and your car will be ready next Tuesday ...
It's your choice what type of shop you go to.

If I were you, I'd look for stronger equipment (rms) and yes, go as big as you can as suggested already ... so if you can do 8" as opposed to 6", do it.
And if you're talking bass louder, if that's what makes your system loud, you probably need something more than the 300-watt sub/amp combo they probably sold you. 600-800 watts to a 12" or 15" ...
