Bronze Member Username: DchrsfPost Number: 17 Registered: Feb-07 | I am planning to buy the JL XR 6.5" Components http://www.sonicelectronix.com/item_1607.html and I want to get a 4 channel amp to power them and my rear 6x9s. I will use a front fill by fading mostly to front, but I still want rear for when friends are in car and dont want them to break up at high volumes compared to front 6.5" comps. They will be in kick panels with the tweets near the side mirrors inside. Which one out of these I have chosen would provide the wattage I need while not drawing too much amprage (105a alternator). I will have the 4ch and a infinity reference 611a (650wrms @ 2ohm to my sub). Some are underrated I hear so I'm including some amps rated @ lower wattage 4ohms. http://www.sonicelectronix.com/item_8014.html - Infinity Reference 7541a http://www.sonicelectronix.com/item_7044.html - Rockford Fosgate Punch P450.4 http://www.sonicelectronix.com/item_7474.html - Eclipse EA4000 http://www.sonicelectronix.com/item_6718.html - Precision Power PPI A600/4 http://www.sonicelectronix.com/item_2791.html - JL Audio e4300 http://www.sonicelectronix.com/item_7733.html - Rockford Fosgate Punch P8004 $300 max budget, but lower the better. This is my first system. I was looking to get the infinity or RF 450.4 Thanks! |
