I just need to know if the crossovers that come with the T1652-S Rockford fosgate have fuses . to prevent the speakers and tweeters from being burn out. or for safety purposes


The fuse like componets in the crossover are not fuses and do not provide absolute protection from the speakers blowing. As you turn the volume up you will notice that these fuses will begin to light up along with the music. Whats happening is as they light up they create resistance to help prevent the speakers from blowing.

Burned amplifier and we cant determine what exactly it is,a capacitor or resistor or something.


Hi, capacitor burning is a seldom case. most burns happens on resistor for they handle currents and suffer resistance.

Polk Audio PSW202 subwoofer. Replaced burnt fuse but blows the next fuse after connecting to amplifier and powering on. What else can I do?


Fuse probably went bad because either the large filer capacitors at the edge of the PCB went bad and or the final output IC mounted on the heatsink(15 pin) fried. Check the capacitors and all the semiconductor components on the board for burn marks or corrosion. You have to remove the heat sink clamp from in front of the output IC to adequately visualize its condition. In fact you might have to remove the large aluminum heatsink attached to the chassis to get a good view of the IC. If it or the heat sink clamp show signs of thermal burns you need to replace it. The IC is a TS TDA7294 mono audio amp available at Mouser Electronics. Replace the 35V 4700mF caps with 50V 4700mF caps. You will only have enough space on the top of the PCB for one of the larger caps. I mounted the other on the circuit side of the board. Note the polarity of the original caps and respect it in their replacements. The fuse is a 5 X 20 medium speed slow blow 250V 2.0A glass fuse.

The fuse keep burning


Somethings shorted inside. Could be the output IC or transistor, diod in power supply, power transformer. Somebody will have to open it up to find out.
It could be a cheap fix like a couple $4 transistors or it could be expensive, like a

Sony SA WX 700 - Fuse (6.3 A 125V) keeps burning out


The switching power supply transistors have shorted out. Other parts may be gone also. A difficult fix. Too bad, it's a great sub.

Cannot get mine to turn on!!


If smoke came out of the subwoofer it definitely did not come from the fuse. One of the amplifier ICs blew. If you know someone who can solder ask him to replace the IC, otherwise just buy a new system, these are too cheap and taking it to a repair shop will cost more than it's worth.

Popped fuses


make sure that the amp is properly grounded, paint somtimes makes it hard for the wire to be grounded, scrape off the paint with a screwdriver or whatever. also make sure that none of the wire are crossed exept if that was done on purpose

Burning smell


The amps do have issues that is for sure - That is where I step in - I can repair your amp and make it so it won't burn up (catch on fire) again. When the amp goes it burns a hole in the board - but it can be repaired. I have done several hundred and all customers are happy :) ... Look for my add here and also on ebay

Fuses


the correct size fuse is based on amps, not volts. The correct fuse rating should also be displayed on the chassis of your sub, if in doubt take the original one to an electrical shop and let them identify it for you.
