Check your main ground, if possible try to read voltage across making sure 12-14v present with load and some signal.

There is a smell in my car every time I play my system for long periods of time. Its a burning smell. Everything is wired correctly and I have a separate battery in the back of my car to power my subs. I...

The problem could either be the amp over-heating or the subs could be over-heating as well. One of my friends owns an Alpine MRD-M1005, and one day they decided to clean it inside and out and realized they had some burnt spots on the circuit board, although they never smelt anything burning, and the amp still works fine.... As for the lights dimming you should probably buy a power Capacitor, atleast a 1 Farad or larger.

Hope this helps.

Makes head lights dim wen bass hits.

You need to install someting called a power cap. the amp needs so much power to produce the big bass thump that the alternator cant keep up. Use a powercap and its like a power reserve.

Amp cutting out when bass hits

With an amp like that you can not pull enough power from you cars battery alone. That is why when it hits hard it drains the amps from your battery and you amplifier cuts out. The light on the amplifier most likely dims when the bass hits. You need to get a capacitor. They are easy to hook up on the main power wire. You can get one from or get a used one off Good luck

Amp clickin in and out

Had a similar problem, mine was a power problem.
Power meaning voltage.
Those big bass speakers draw lots of power. My original alternator couldn't keep up.

Question: Do your headlights dim in rhythm to the bass hits?

If so, your sound system wants more power than your vehicle is producing.

My first solution was a high output alternator. It worked great.

Then I added another amp. Not great anymore.

My second solution was to tie in a large capacitor to the amps power supply. (These a big (1 farad), about the size of a Pringles can)

Your amps power consumption is not uniform. Each time your amp punches the bass, it draws extra power. If that power isn't available, it starves and shuts down (if only for a second) then restarts.

The higher the gain, especially using a low pass filter, the more power needed for each thump. Thats why when you turn the bass down, you can get higher volume from the rest of the system.

How a capacitor can help (simply put):
In this application, the capacitor acts like an auxiliary battery, smoothing out power fluxuations. The capacitor builds up its charge literally between bass hits when power demand is low. Then releases it's charge when the demand is high. Think of it as an on-demand power boost.

Hope this helped
