Car audio amplifier help?

Car Audio experts help me i've got some choices of head unit, amplifier, and speakers?

• Hello all that can and willing to share me your general logical thoughts. I will be getting a car in a couple of months and i am willing to buy it a full sound upgrade. I've made some research and realise i need to upgrade everything to the head unit, to speakers itself, and amplifier is a must for beast surround sound. The point i'm trying to do is make it a good surround sound, to defeat local competition, to enjoy every song like it's the first time its listened to, for it to be excellent in well anything and everything. These are the products that I had in mind, they will be bought from amazon and ebay, but are new and they are all Alpine. This would be my head unit , alpine CDE 121 http://www.ebay.com/itm/Alpine-CDE-121-CDE121-In-Dash-CD-MP3-WMA-AAC-Car-Receiver-Head-Unit-/290649105772?pt=Car_Audio_In_Dash_Receivers&hash=item43ac09656c#ht_2322wt_1270 This would be my amplifier, alpine 500w http://www.ebay.com/itm/ALPINE-MRP-M500-CAR-AUDIO-MONOBLOCK-AMPLIFIER-500W-/290649421518?pt=Car_Amplifiers&hash=item43ac0e36ce#ht_2125wt_1037 This is going to be my car speakers, alpine speaker, 80 watts http://www.amazon.com/Alpine-SPS-600-speaker-2-way-coaxial/dp/B0013FMWPC/ref=sr_1_6?ie=UTF8&qid=1324961257&sr=8-6 what do you think?bang for my buck?

• Answer:

  Alpine is a good reputable brand and your selections are all good products. However, the Alpine MRP-M500 amp is a "monoblock" amp intended for powering subwoofer(s). The SPS-600 speakers are 2-way, full-range speakers. You don't show a subwoofer as part of your selections. If you are not planning on installing a subwoofer, you should consider a 2 or 4 channel amp depending on whether you are replacing just the front speakers or both front and rear. http://www.sonicelectronix.com/item_12020_Alpine-MRP-F300.html But, my recommendation would be to keep the selections you list and add this subwoofer. http://www.sonicelectronix.com/item_9331_Alpine-SWS-1023D.html Power the speakers from the head unit built-in amp and the subwoofer with the MRP-M500.
