Default kicker DX700 problems

I bought this amp awhile ago on ebay, and finally tried messing with it.
The problem is I can only get sound if I ground the rca's to the case.

Try looking under the board for a Pico fuse or a open SMD cap in the RCA ground trace. This is a very common problem on this era of Kicker amp especially after the amp has been abused and over driven into clipping. Hope this helps

If the Pico fuse only has the letters TH than that is my problem.

Might there be a way around that, or is that to keep from wiping out the whole preamp section.

If the fuse opened, it opened for a reason. Generally, when they open, I find shorted power transformers. They will also open if the speaker wires short to ground or if the non-signal speaker wire contacts a 12v source.

The mouser part number is:
576-0468001.NR

Order extras.

To check for a shorted transformer, ground your scope to the chassis ground of the amp. Connect the secondary center tap of the power transformer to the chassis ground via a relatively high value resistor (1k-10k). Connect your scope probe to the center tap of the power transformer. With the amp on and ALL transistors clamped to the heatsink, twist, push, pull on the transformer. If the line on the scope ever moves from its reference point (0v, ground), the transformer is intermittently shorted.

I don't have a scope yet , and I bought the amp on ebay so who knows what happened to it.

Is there anything else I should check before I order the fuses?

You can use a 12v lamp in place of the scope. You can also use your voltmeter set to DC volts but neither of these will be quick enough to catch a really quick pulse.

I replaced the fuse and checked the best I could for the transformer to be shorted.
I didn"t find any thing wrong with the transformer.
It is playing fine with no noise except when I adjust the gain it sounds scratchy.

Theres other fuses on this amp? If so i had no idea because i'm currently having a bit of trouble my self with this amplifer. My problem is trying to find the right Resistance value for the Gain knob. It wont play with out all it just does is make a loud screech sound.

I got it done already with the help of my electronics teacher at school. And i must say this amp is really inpressive and more power than i probably need for two ten inch Rockford Fosgate Punch XLC's. This site is very handy when need and the people are very helpful.
