Halfway done with complete audio system, need help though
Several months ago, I happened upon a pair of 400 watt (200 rms wattage) 4 way 6x9'* from Lanzar that I stuck in the back of my 95 SE. They sounded great, but they lacked the power that only an amp could give.
A couple days ago I went out and bought a $200 Alpine headunit with 3 preamp outs, a pair of 180 watt 5.25" Sony Xplod speakers for the front, and a 1200 watt (200 rms watts to 2 channels @ 4 ohms) amp for the back. I hooked up the amp and ran the wires (power and audio on separate sides, of course) to the trunk, and when everything was said and done, I fired it up and took it on the road.
The 6x9'* are thumping like crazy, and they sound great. Before adjusting my gain (i think it was the gain, it was a dial measured in V, I assume for volts) i could turn the volume up to 35, which is the max for the HU, and didn't encounter distortion. I adjusted the gain and the bass boost, and now I simply won't turn it up past 28 because it'* waaay too loud to do that. On to the question.
When I turn the volume up past 23 or so and the bass hits, I hear a pop come out of one or both of the speakers. I'm not sure what it is, but I don't want to blow them either. If anyone can help me diagnose the problem, I'd be grateful.
Also, once my installation is finished (I'm going to amp the front speakers cause I blew the current set maxing out the back ones) I'll get some pics up.
Edit: Also, I have 4 gague cable powering an amp that'* putting out 400 rms watts. Can I add another 100-200 rms watt amp to the same cable (via a PDB) or should I run another one?
