blown two zx 700.5s and two deq 9200a - Page 9

rolexcomm · 3rd December 2009, 03:07 PM

no, didn't have more than .001 on any channel, Yes the relay clicks in. Now that I have this thing mounted up, It is starting to blow the inline fuse. And makes a hissing sound out of the mosfet area. It won't let me keep it on long enough to determine exactly where it is from. Also the c15a gets really hot real quick. It gives me about 10 secs. before it blows the fuse.

Are all of the insulators in place between the transistors and the heatsink?

There are two screws with lockwashers that must be in place and tight. The washer is vitally important. Are these in place and tight?

Perry, I am sure mine never had those washers on it. We do mercedes, bmw dash work and are very very careful when we take things apart. Mine has two plastic spacers installed that make sure the screw never touches bottom. I have installed the washers and it quit hissing and blowing fuses.

Does it produce audio now?

rolexcomm · 3rd December 2009, 05:14 PM

Amp 1 works all channels. Amp 2 dead. The sub channel works but we have a low voltage and it didn't seem to have enough to keep the speaker moving. I was testing with a woofer. Didn't have anything smaller on hand to try with.

For amp 2, did you try the switches in all positions and the correct set of RCA jacks?

we are using an ipod and had to disconnect from amp 1 and connect to amp 1 to try amp 2. Yes I tried in all positions.

Perry Babin · 3rd December 2009, 05:36 PM

Are the gains at the max position?

Short the shields of amp 1 to amp 2 while driving signal into amp 2. Does amp 2 produce output?

rolexcomm · 3rd December 2009, 06:33 PM

no gains aren't in max, but tried moving up and down. But, this time we turned it on and amp 2 worked. Doesn't sound exactly like it should, not alot of bass but it worked. We let it run for about 20 min and it worked the whole time no smoke or anything..

That !@#$%^& ipod is likely the cause. Try it with a standard head unit that's grounded to the same power supply as the amp. If the crossover is off, it should work properly (although I've seen kicker amps do some strange things on the second 2 channels when there was no shield ground connection to the first two channels).

The problem with the sub channel may be the same as it was for amp 2. Again, try it with a standard head unit.

If you don't have a standard head unit, short the shields of the sub channel to those of amp 1.
