  1. I have a few 3000 watt RMS amps left. They were samples from a company I was trying to get started. They are an established build house out of China that wanted to come into the US market. Because there is no warranty (new amps) and I don't have replacements I'm willing to part with it for $400 shipped. Paypal only. It will come with a birth sheet of actual power (some of it is written in Chinese)

  2. Cold air can give you more SPL (on the meter), but not be as loud to the ear. I made a topic about this last winter. Warm up the subs before slamming them in cold weather, the spiders especially don't like sub-freezing temps.

    this. there is also the issue of condensation if you don't warm them slowly. you can get moisture buildup on the VC's. water damage is bad. Same goes for your HU. especially touch screens. if you have a remote start...USE IT. if not...GET ONE. 5-10 minutes before climbing into the car will make a world of difference

  3. Basically I've been having problems wiring my head unit in the past because the factory harness was cut out of my car and I can't figure out how to get power to the head unit or the ignition wired. I just bought some Crescendo 6.5's and tweeters with a crossover and have no idea how to wire everything.

    I then called up my local car audio store and told him I had 2 crescendo mids and 2 tweeters with a crossover plus a Hifonics 4 channel amp..he said that the amp is unnecessary and went on about something about the High Pass/Mid Pass/Low Pass and I would only have High Pass if I use that amp. If I connected all the speakers to the head unit, then I would have High, Mid, and Low pass. What should I do in this case? I mounted all the speakers and have wires running into the cabin, and the car audio store said they would wire the head unit to the speakers Monday for $60 but I want to do it myself and by tomorrow. Any suggestions? Maybe someone could give me their number and could walk me through this shit hahaha..thanks.

    I had this issue several times when i first started car audio. Here is the simplest thing in my opinion. The red wire goes from the radio to the positive side of the battery. The yellow wire will go from the radio, to a switch, then to the positive side of the battery. If you think you will have an issue with leaving the radio on when you get out, then wire it to a fuse that cuts off with the car. But I like the switch b/c if you go to a car show, or a parking lot, you can leave the radio on without leaving your keys in your car. Then lastly, run the black wire from the radio to a ground in the car, or the negative side of the battery. One more FYI tidbit, do not run the wires through the door jams. Drill a hole in the firewall, then run the wires through the hole. Make sure you use a grommet on the hole, or cover the wires in split loom. Here is a diagram that might help you out.

    you got that backward....yellow is constant, red is switched.

    @OP - what kind of car...year, model, make, trim level...I'll tell you exactly which wires you need to use. If you can't find a constant signal the fuse is probably blown (this happens when thieves cut the ground and power at the same time)

  4. So your saying just get a 150A then get a second holder and get another 150A?

    no need. as long as the holder can handle the high current (some are rated lower than others due to heat) you can take the plastic off them, or just bent the tabs a little and stack them directly. i've been doing it this way for years without issue, as long as you have a solid connection for them.
