Coil Head Amplifier
subwoofer Bass cuts off when i turn up volume?
i have an alpine amplifier (dont know the model out the top of my head) but i think its an 800 watt amp, i have one 12" kicker cvr and a 12" infinity sub (my other kicker's wire from the voice coil detached) but anyways the problem is when i turn up the volume to about 7 or 8 depending on song and bass settings i have, the bass goes out and dosnt come back on until i turn off the car and turn it on again.it happens all the time.i cant go past volume 8 without the bass goin out. it was working fine till about 2 weeks ago, ive had it almost about a year now, does that mean my amp is not good anymore? i berly bought a battery a couple months ago so it cant be that. any one know?
could be as simple as resetting the gain settings (mine got out of whack with no explanation) that would cause your amp to shut down, other than that i don't know what to tell you

Reasons To Have A High Quality Car Stereo System
So you've spent thousands getting your car ready for show. New paint job, tricked out suspension, phat rims, you've got it all. But what about on the inside? A bumpin' system can be THE difference between a cool car and a truly awesome show winner.
While a killer system can make your car that much cooler, having a crap car stereo system can totally kill your cars coolness factor. This is never good if you've already spent a lot of money tricking out your vehicle. Even if you have something less than fantastically good looking, having that killer thump is guaranteed to make more people actually want to ride in your car. By the same token, a pathetic car stereo system can make your car have even less appeal than it does now.
So What Makes a Killer Car Stereo System?
Quality and attention to detail pretty much sums it up. You will never be able to get the best sound out of cheap parts, and they are more prone to failing (usually at the worst possible moment) than the more expensive parts. Little things, like the frequency of a crossover, your EQ settings, and small variations in speaker placement can make a huge difference in the overall sound of your car stereo system.
Listen around and see who has systems that sound good to you. If you can listen to several different systems in the same kind of car as yours, you will be able to get a much better idea of what sounds good and what doesn't. But even if you are listening to different car stereo systems in different vehicles than yours, you can still get a good idea of what brands of gear you like and which ones to avoid cause they sound like crap. Remember, whatever sounds the best to you in your car is the best for you! No one else can tell you what is sounds good, because listening is a very subjective experience.
Car stereo expos and conventions can be another good way of gaining listening experience, and you will usually be able to check out more different systems at one than you can find on the streets.
Whatever you do, unless you have a truly awesome factory car stereo system, you will want to replace that head unit and speakers. The difference, even using factory mounting locations, can be the difference between night and day. Your mids will have more punch, your highs will be clearer and brighter, and the bass will have that bone deep thump everyone loves. Adding at least one amplified subwoofer will make a huge difference as well. You just can't get the same bass out of a 7" woofer as you can out of a 12" subwoofer.
Amplifiers are the driving force behind your car stereo system. Skimping in this area is extremely dangerous, not only to your sound quality, but to your speakers as well. An underpowered or cheaply made amplifier is prone to what is known as clipping. Without getting too technical, what this does is send a large amount of direct current through your speaker, causing the speaker coil to overheat and melt. This leads to the infamous "blown speaker". Coil overheating is the single biggest cause of speaker failure. Putting too large of an amplifier on a speaker can cause the same thing to happen. Always match up your speakers' power handling ratings to the output of your amplifier. For instance, let's say you have a 4 channel amplifier that provides 1000 watts total power. That is 250 watts per channel (1000/4), so your speakers should be capable of handling that much power, or you risk blowing them out.
Having a killer car stereo system is something your can be proud of, and dramatically increases your cars coolness factor and resale value, no matter what vehicle it is installed in.
