I would like to know how to hook my lanzar amp to the high level outputs in my 2004 grand am gt it has the monsoon sound system, it is going to drive 2 Visonic 10s bridged and a set of Pioneer 3-way 6x9s with it in the high pass mode, i would still like to use the factory amp for the front factory speekers. ANY help please jay

Repair cost would exceed replacement cost. Try disconnecting all the speakers and see if it works then. Try reconnecting each speaker by itself and see if that causes the problem. Most grand am have the monsoon sound syatem...even if they aren't labeled as such. Pull the carpet in the trunk on the left (drivers) side wheel well. The monsoon amp is located over the wheel if you have a monsoon system. If you have to remove the amp then you must change the speakers out or rewire them as the monsoon system uses bi amp speakers. Most of the ga forums have extensive write ups on this system.

Unless the face of the stereo says MONSOON there is no separate amplifier. On a Non-Monsoon Delco system all four amplifiers are built into the stereo, Left front, Right front, Left rear, and Right rear. Monsoon systems do have a separate amplifier which basically boosts the output of the four regular amps in the radio. I can't imagine all four of those amplifier output chips going out at the exact same time. I would pull the stereo and check if all plugs are seated properly. If those were all securely plugged in I would (myself) inspect the inside of the unit for the cause of failure. For example all four amp chips pull power from a common point and if one chip had a severe enough short in it, this may have caused the power feed trace on a circuit board to overload (too much current going through it) and created an open which killed power to all four of them. Any good electronics repair shop worth their salt should be able to repair it if you can locate one willing to try. It may only need a circuit board trace repair and one amp chip replaced.

everything depence of system you putting in your car if u have no amplifire you connecting the speakers to radio as they marked i you putting one in, your speakers wires goes from amplifire to speakers there is no diffrent way of connection. also the diameter of your wires have to be adekwate to power u going to have in your system for optimizing the sound quality let me know if this help ya

Try cleannig the contacts with a soft black lead pencil and see what happens

the 50 C was used as a cheater amp back in the 90. You will be shocked by what this thing is capable of doing you can run an entire system subs mids and highs off of this 50 C. About 1300 watts

did you run direct to the speakers or to the rear of the radio to split factory wiring. Check to make sure that you are connected to the correct side of the wiring behind the radio. If that is correct, then check the input of the amp. Try a different source and see if you get signal. Make sure your wiring is not crimped.

I use my ipod and hook it to an 1/8" x RCA splitter and plug direct in the amp. try to isolate the amp as much as possible. 1 speaker to outputs and 1 source you know works. Then test from there.

Tap into a signal wire (rear speaker wire) using a line level converter.
These convert the High level speaker wire output into low level RCA output that is accepted by your amplifier.
Get a good one Pacific Accessory Corporation (PAC) sni-35 is the best IMO.
The TRUNK-LOC is the SAME as the SNI-35 - but it incorporates a voltage sensing input - so you dont need to run an additional turn-on wire. The voltage is sensed through the speaker wire - and it turns on the amplifier.

Then you will need a fused power wire from the battery,
Ground to chassis, and remote turn on lead (if you use a standard line level adapter).

An amplifier installation kit will give you everything you need to add 1 amplifier (except the converter)

You would need a Line Output Converter (LOC) to convert the speaker level of the head unit to preamp level.

The amp also has speaker level inputs but the LOC will probably produce better results.

Let me know if you have any other questions.

Do you still have the controller??? I need one

Pulling to much power? Do you mean clipping? When an amp is over powered (gains are to high) a amp will distort much like a deck destorts at high volumes and it will sound horrible. Make sure your setup is to within specificatons of the amp. (impediance and such)
