If you want to upgrade your system and are on a budget alpine speakers and subs are the way to go but don't get an alpine amp because they always advertise their amps about about 200-300 watts than what they actually are so go with the rockford or mtx. the sub that I would reccomend is the 12" alpine type R is the best bang for buck and go to onlinecarstereo.com to get everything, all their products are from 30-60% cheaper than any stores or sites that I've looked at so good luck with your stereo project, keep me posted.

 

I second that. Additionally, Im selling my two JL Audio 12w7 subs and my variable impedence Phoenix Gold Ampin the "for sale" forum. Subs are 6 months old. Amp is a year old. $800 shipped for all three.
they take up too much room in my TT and Im ready to have my backseat back.

Just an FYI.

 

Warning: This is a long read, use at your own risk. This is a little hard. The thing with audio is, it’ll cost you what u can afford at the moment. There’s no simple and definite answer. There are way too many variables here. For example: how complex do you want to make the setup? There’s really no limit on what u can sped other than what you’re willing to spend on it. There’s no "best" end-all system out there. The best one for you is the best one u can afford. If u don’t have all the money right away, do it by parts. Start with a good head unit, get speakers, then sub amp and sub, then speaker amp. Do work on insulation, tuning(u might need to get a nice eq). A good way to start planning is to write out a list of things u will buy and then research for best places and deals. Then go to a bunch of audio shows and see what the people have. If you meet a person and ask them about their setup and they start talking, you’ll know if they know what they’re talking about. If the only thing they know is the brand name, say thanks and move on, you won’t get far there. See if you can go to SQ(sound quality) competitions instead of the ones that just have cars meter on a dB meter for loudness. Another piece of advice I can give you is that when you are about to buy a product, check with the manufacturer about next year's line. Most companies update their lines annually and you should see what’s coming out next year, if the info is available. It will help you make a decision about getting this year's model or waiting for the net one. Go to sites and learn as much as you can about terminology. You will need to know that stuff before you start looking at specs for equipment. There will be things that are identical for all brands and some things will be exclusive to a single company. There’s also things that sound exclusive, but everyone has them, just under a different name. Do not just go into a shop and say "I want it to be loud", put down money on the table and leave. This is no way to get equipment. You won’t be 100% happy with that. Pick the stuff that you want. Read about what manufacturers put into their equipment as far as functions and features. Compile a list of the things you think you want and need. Definitely learn what the technology is. If they call something "true bass" for example, learn what that does, do not just go by the name. My eclipse head unit has something like that and if used incorrectly will blow out tweeters and damage door speakers. It has nothing to do with the power output, in this case its crossover setup and eq'ing it right. To me, personally, clarity is the number one priority. So my setup is going to be significantly different from the average setup, plus I plan to compete with the Audi. Make sure you don’t buy things on impulse, because in a month you’ll see something better or a lot cheaper than yours but uve already sank the money. Look at lots of equipment and compare prices, and you’ll see an average price range for all equipment in its class. For most people a speaker is a speaker, which is true to some extent, but not all the time. Their sizes, manufacturers, impedance, materials and etc differ, so the sound will differ also. Keep in mind that all cars sound different. Even its two identical Audis, they will have slight differences in sound. This is normal and is to be expected. To remedy that, get a nice eq and it’ll make up for the deficiencies in sound. I won’t just start listing off brands and what I think of them. I don’t think it’ll do you good. You’ll only thing I’m a snob with money. It’s not true, in reality. Just because my Audi equipment costs more than your neighbor’s civic doesn’t mean anything other than I'm an audiophile. A bunch of people I know ask me about audio advice and consider me a guru, but I don’t think so. There’s people with much more extensive knowledge, I just try to learn as much as I can, so I don’t have to keep asking questions. There’s really nothing wrong with asking questions about something you don’t know, but I digress. In general, I found it extremely helpful to learn everything you can about what you’ve got in your car. I lot of people will just give me the names that are written on boxes or brochures, but they don’t know anything about their car's setup. its not that you’ll be quizzed on it, but that if you decide to change something, or add something, or if something breaks, you’ll be able to figure out most of it by yourself and wont have to go online for hours searching or spending money to get it figured out. Something as simple as a blown fuse can confuse people for a week. If you want to know what I've got planned for my car, the build process or my equipment list, I can tell you all of that and show you photos. It’s not a secret by ay means and I don’t mind helping. The most helpful thing for me is to see the car in person if I’m helping somebody, but if they’re in a diff state then a bunch of photos will work. Also, remember this, more money doesn’t mean more better. Power isn’t everything also. You can have 6000 watts but if it sounds like crap, then what’s it all good for? Why spend the money and time and not get something that you’ll enjoy. When picking out product, keep this in mind: looks should really be last. Most things that are shiny and have lots of pretty lights and flashing things will end up sounding sub par. they only sell because of the chrome trim and the blue glow under it. You don’t always have to buy top of the line product either. There’s no sense for paying for things you wont be using, like some functions in the equipment. Figure out what you want to do first, then find equipment that suits that purpose. Don’t copy somebody's system as is, it wont sound the same for you. Try to see or hear the equipment before buying it. Go into electronics stores and play with a bunch of head units to see what you prefer. Do you want buttons or *****? There’s a ridiculous amount of equipment available to consumers today, so don’t just settle on the first thing u find that seems good, keep it in mind for later choosing. As far as install work goes, if you cant do it by yourself, have a shop do it. Yes it will cost you more, but you wont goof it up and accidentally connect two wires and have a meltdown(literally). Also know thins, Audis are notorious for being tough to work on. I’m learning this more and more as I do work on mine, but it doesn’t scare me, I like a challenge. The thing is, if you plan it out well ahead of time and take your time and do things right, it’ll be worth it in the end. Don’t take shortcuts and cob job things, it’ll backfire on you, you might damage expensive equipment. I’m going to wrap this up, because I don’t think you guys want to read a book on "how to pick out and put together an audio system guide by Vadim". Let me know if you want me to clarify anything or if uve got questions in general. Its fine that you’re new at this, remember all of us were at one point, till we asked questions and got the info. Good luck with your learning, selections, purchasing and building/installation. Keep us in the loop with photos and updates. Hell, I might see you at competitions in the next two years, who really knows?
