I went over a bump and heard a pop over the speakers and it stopped working, no rattle, all wires still connected, replaced fuses

That would be the main board. You can get a new one here : TV Parts Universal TV Stands DLP Chips ShopJimmy

That was a DEAD Electrical short. If your talking about all the bulbs, it's probably at a fuse box. Start by checking all the fuses (under the hood too) Ck all the fuses anyway and that's the circuit where the trouble started if you find a bad fuse. More than one or two fuses your best bet is pro help unless you have wiring diagrams, test light & multimeter. Also look for burn marks on the wiring where you heard the POP.

i would suggest replacing it rather than fixing. The cost of the repair will be about the same.
if you went to a passive sub/seperate power amp setup you could get a much higher quality unit, but it would cost you considerably more cash.

Check the convertor in exhaust could be broken up.

Betting that you've got a wiring issue on the back of the radio. Pull the stereo & check your connections. Somewhere the speaker wires came loose.

Check the connection to the bulb, unplug it and put some electrical connection grease on it.

Could be your head unit or the connection to the speaker may be bad. Also if the wire to the speakers in your ceiling is bare and touching any ground it would interfere. Start by checking connections by playing something and messing with wires. Listen for a difference. Next check by putting the wires that power those speakers in a known working output and listen for different quality

No jacuzzi magnums do not have a reset button. First make sure breaker to pool is off, then remove rear motor cover, and take a look. Popping noise sounds like an arked wire. Could be a bad terminal or just aloose power wire. JACUZZI PUMPS ARE GOOD QUALITY, AND USSUALLY RUN FOR MANY YEARS. Pump can be removed for repaair, or motor replacemant by a qualified, and republe pool shop, for rebuilding Ussually rebuilding is about half the cost of new. Kirk
