Red LED "Protection Light is on" What is the problem
The red light means the amp is in protection mode. A few things can cause protection mode.....
First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs.
Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood.
hope this helps
Crunch 2000.4 car amp, need help tuneing
re-check the speaker connections are correct and use a matching ohm test speaker on the other connections for a sound check. Sounds like hi frequency output into the sub amp. Sub-woofers are a mono signal!!
Does crunch blackmaxx take aux for iPhone?
The amp is a discontinued model, but I do think I found the specs on it. It will produce :
350 Watts X2 @ 4 ohms
700 Watts X2 @ 2 ohms
1,400 Watts X1 @ Bridged at 4 ohms
It is designed to be ran inline between your stereo and a set of, or a single, sub woofer.
This could be a significant amount of work for a beginner in car audio, but it can be done.
I would do a little research and decide if you want to use this amp. Join in on forums like

I unpluged my amp from
There should be a group of screw terminals. They should say pos or (+), remote, and ground, GND, or (-). This is the power terminal. The power from the battery goes to the (+), the remote turn one (thin wire) goes to the one labeled remote (usually inbetween the ground and power wires), and the ground to the (-). RCA jacks should be labeled input and output. Plug the appropriate colors in the input ones. The speaker terminals are labeled left and right + and -. If it is a 4 channel amp, it will also have front and rear. Depending how you wired your speakers is how they will go to the amp. Follow the speaker wires to the appropriate prongs positive or negative. Hope this helps.
Dont no how to
Please be a little more specific on what you can't hook up.
I have a crunch p1500.1
There a few different issues that could be troubling you.
1. The Amplifier's outputs are no longer working
- To test this, connect the negative probe of a digital multimeter (DMM) to the negative (-) terminal of the amps speaker output. Connect the positive probe of the DMM to the (+) terminal of the amps speaker output. The output terminals you are referencing should be the output to the same speaker. Set the DMM to AC Voltage/lowest setting. If you read AC voltage than the outputs are ok. If you show no reading then the outputs are bad. Stop here and get the amp repaired or use as a paperweight.
2. Check the RCA connections behind the radio. They may have come undone. If so, re-connect and dance for joy as you once again enjoy music in your car.
3. Confirm that your RCA connections to your amp are plugged into the INPUT and not OUTPUT or THROUGHPUT. If in the output or throughput then move to the input. refer to the last sentence in #2 above.
4. Your RCA connections/or RCA cables are bad. Use the above mentioned DMM to check for continuity in the RCA's to ensuyre they are in working condition. You can also use the DMM set to ACC voltage like in #1 above to check to see if voltage (speaker signal) is being sent to your amp.
5. Make sure the amplifier's gain setting is not turned all the way down. If so, adjust accordingly.
If none of these solve your issue then most likely your amp is beyond the do-it-yourself repairs.
