[QUOTE="yacob.naif, post: 1711517, member: 565696"] Hmmmmmmm. Well, you want to set a high pass on your drivers depending on the quality of the speakers, and the way they're installed. 99% of the time, door speakers are installed in free-air conditions, so they don't appreciate slammin' really low bass, where the resistance of the speaker drops, and the speakers move around a lot. Without knowing what speaks you have, or how they're installed, i'd tell you to set the HPF @ 80, or if they're in custom kickpods, or sealed enclosures, lower @ 60-70hz is fine. Set the LPF on your subwoofer to the same frequency you set your HPF to. If your subs are in a ported box, you need to find out what the box is tuned to, and set your subsonic filter (could have a different name on your amp) to ~70% of the port's tuning frequency to keep the sub from unloading trying to play frequencies too much lower than tune, not to mention ported enclosures usually have a ridiculous dropoff, with a -3db rolloff around 5% under tuning frequency anyway. Set your x-overs @80 or 60 respectively like i mentioned earlier, and then just play around with them a bit. If you notice bass notes on your door speakers buzzing or rattling, or distorting, turn the HPF up a bit untill it goes away. I wouldn't crank the LPF on the subs up, tho, leave it no higher than 80, a small gap in response wont be noticeable for the most part. As for your tweeters making your amplifier turn off? That's a new one. Make sure they set the gains correctly. Gains are NOT volume controls, there's actually a proper way to set them, you don't just pick and choose a gain level to set an amp at. They can be turned DOWN from optimum setting, but UP can cause damage of your equipment, and fast destruction of your speakers and sub. Also make sure the ground connections are good on the amp. The only other thing i can think of is that the wiring in the car is pinched in a doorjamb somewhere and grounding out, causing the amplifier to self-protect, or you're clipping the hell out of the amplifier (gains too high) which is overloading the amplifier, and causing raw dc current to be sent to your speakers through your channels. Either way, make sure you figure out what's wrong before more than your amp end up broken. Summary: 1st, fix your gains, something's going to break 2nd, speakers hpf 80hz 3rd subwoofer lpf 80hz 4th subsonic filter @ 70% tuning frequency (eg.; 30hz box: 21hz ssf/ 42hz box: ~30hz ssf.) 5th go make some noise. Lastly, i wouldn't advise using bass boost at ALL, unless you have access to a oscilloscope. You want to turn the bass boost to the level you want, or the highest setting even better, download a -3db test tone of the central frequency of the bass boost slope, and set your gains with the oscilloscope with the bass boost ON! Or if you have no idea what i just said, leave it off or you're gonna blow your speakers up and be very sad. [/QUOTE]
