'94 G-Limited. I've got a pair of 6x9s set behind my seats instead of a the rear speakers in the door pillars. At the weekend I fitted an amp to "assist" said 6x9s. The amp is a MaystarQXA250 2 channel so not an enormous amount of power but then I only wanna a little help. The 6x9s are Fusion Powerplant. Anyways, all wired in and working sweet. Then the following day I unlock my car with the key fob remote, never a problem before, but this time the car didn't unlock, the indicators just flashed rapidly and the alarm disarmed. I unlocked it using the key, started the car and drove off. Then I start noticing things. The volt meter drops below halfway for a second when I use the brakes, it bounces when the indicators are on, at a junction when the car is ticking over the rear speakers connected to the amp are cutting in and out like its not getting enough power. Also the alternator belt tends to squeal when I pull away from junctions. When I got home the alarm would set but not lock the doors. I've driven it with the stereo off with not much difference to electric system but I can hear a buzzing from the stereo even though its turned off and the power light on the amp is off. I've taken the fuse out of the amp power wire and lo and behold the alarm locks and unlocks from the remote again. This bit may sound stupid but I've got the power lead coming straight from the battery, should I of taken the power from the + in the engine bay??I'm thinking the amp will be coming back out but I am curious to know where I'm going wrong.
Any ideas?
