What is the best sub and audio system you recomended for a nissan altima 2002?

I just got a nissan altima 2002 and i want to install an audio system,a sub, and speaker that i could blast my music?


What is you guys best advices for me?|||http://spkrbox1.spaces.msn.com/Default.a鈥?/a> for real "sound" advice.





Your system won't mean squat without a well designed box to put your subs in. Some manufacturers have recommendations as to dimensions of various types of boxes. It is best to find someone who builds boxes if you go with something other than a sealed box.





You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as impedance's(resistances).





If your amp is rated at 4惟 don't subject it to 2惟, it will fry.





Here is the formula for subs in parallel:





Z = 1 / (1/sub1 + 1/sub2 + 1/sub3 + ....)





For series, just add them up (sub1 + sub2 + ...).





You can mix and match these equations to get the right impedance required by your amp.





Example: 4 subs @ 4惟 each. If I connect two in parallel and the other two in parallel and tie the two pairs in series, I would have a total impedance(resistance) of 4惟. So to the amp, it's just one sub.





You should use a capacitor as well.





Recommend for every 500 watts MAX you use a .5 Farad cap


Example: 1000 watts MAX - 1 Farad cap





Try http://www.soundomain.com/shop you can find some really good deals, and this site is manufacturer certified. VERY IMPORTANT WHEN SHOPPING ON-LINE!!!





You will also need what's called a "line level converter" if your stock head unit doesn't have RCA outputs or your amp doesn't have high-level inputs.





If you like I can send you some plans for reference. My plans are for a 4-th order band pass bass box that holds two 12's. Also included are java calculators you can use to figure parallel and series values given 惟 values.

My system





Blaupunkt TSw1200 subs with a Sony Xpl艒d XM2200GTX.


My amp is 1200 watts, subs are 600 watts each, cap is 1.2 Farad





SPL is about 112 db





Total cost(so far) = $410|||Anything by Rockford Fosgate ROCKS!!!!|||Get a Jl Audio 12w3, and a 400 watt amp made by a reputable company. For speakers, I would go pioneer or eclipse.
