hy , I`m new in this stuff, so if anyone can help me i really appreciate it. so ... I have an amplifier, JBL GTO 1201.1 mono channel , with 787w rms @ 4 Ohm. I think I`m gonna buy a subwoofer Pioneer ts-w3004 spl with 1000w rms @ 4 Ohm to connect it with my amp. also i wanna put 4 speakers , 2 in front doors and 2 in back panel, some Pioneer TS-A1681R 6-1/2" or Pioneer TS-A1682R with 50w rms. I wanna connect these to an dvd-player in-dash , also from Pioneer, maybe a AVH-P4900DVD or a AVH-P5900DVD. I have a VW Golf 4 with 2 doors from 2001. I have only one battery and I wanna put an 1F capacitor. now I`m asking for your oppinion , is this system gonna sound laud and clear? and if not , what do u recommand me to change?
