Thread: Amp protect light on :(

it's a 4 channel 1000W amp. When I felt it, it did feel quite hot :S.

Are there any troubleshooting methods u guys have?

I have a blaster bl-1000 amp.

I have the amp plugged into battery through 30A fuse. Sub bridged with 2X250W ports. The 6X9's and 5.25"s are plugged into remaining 2 250W ports.
PC is plugged into battery and ground is in amp ground port (also grounded to chasis).
The amp turns on via PC remote (m4-atx).

Anymore info needed please state

Thanks

are the 6x9's and 5-1/4's wired in series or parallel, and what is the end load on the amp(measured across the output terminals of the amp)?

also, what type of subwoofer(brand, model #) and how is it wired if it has more than one voice coil? and again, what is the end load on the amp?

how hot did the amp get? most amps, when they get hot enough to go into protect will be hot enough to burn you.

I did a very brief search(very brief) and did not see anything about the amp being 2 ohm stable, so i have a hunch that you will find that either the end load is 2 ohms(for either the sub or speakers) or that you have a grounding issue.

The 6x9's and 5.25" speakers are in parallel.
Amp speaker ports (250W) each.
1) One Kenwood KFC-M6942A speaker and Kenwood KFC-1350S speaker both in parallel.
2) One Kenwood KFC-M6942A speaker and Kenwood KFC-1350S speaker both in parallel.
3 + 4) Bridged kfc-w3011

The amp was definately not hot enough to burn me, so I guess that's out of the picture.

How do I measure the end load?

Thanks

o and before I replaced the HU for the computer, I had all speakers except the 2 - 5.25" speakers plugged into the amp all running fine.

to measure the end load, unplug the speakers from the amp, and put a ohm meter across the 2 connections.

I think that this is where the problem is-- having 2 speakers parallel for each channel will produce a 2 ohm load. try hooking the speakers up in series. this should produce a 8 ohm load, but will be alot quieter, and will not send the amp into protect.

ok, I will give that a go. At the moment I'm sorting out yet another problem, hopefully I will get a chance to test it tonight .

Thanks for your help.
