[QUOTE="EpicMango, post: 7620162, member: 639134"] So. I've been doing a lot of research on the sub system that I want to buy for my car. Lets get all of the details out first so you know whats up Car information: *1994 Honda Accord *Stock 80 amp 12v Alternator *Stock Battery *Boss 612UA Headunit *Kenwood KFC-1662S 3 ways in the front *Sony Xplod 4 ways in the rear deck Planned System (Budget *2x Kenwood KFC-3013PS 400 watt RMS 4Ohm 12' Subs - $100 *Kenwood KAC-8105 500 watt RMS 2 Ohms (2x30 amp fuses) - $100 -OR- *Kenwood KAC-9105 900 watt RMS 2 Ohms (3x30 amp fuses) - $170 *Atrend E12DSV Dual 12' Ported Box - $53 *Rockford Fosgate 4AWG Amp Wiring Kit (60 amp fuse) - $30 Prices are with brand new unopened products. If I go with the KAC-8105 Amp, I'll be paying $348 total including installation. System Expectations: *Want the lows, especially in the 30-50hz region to really punch, more emphasis on the 35-45hz hip hop bass, I want the lows to hit nicely, and with a good 115-130dB loudness. Now based on this information I have a couple questions. 1. With my alternator listed above, would my car be able to handle pulling 500/900 watts RMS from the respective amps listed. 2. I don't want my speakers to play bass. I want the subs to play bass, I want the speakers to play everything else, do I need to have a 5 channel amp to achieve this, since my HU doesn't have a crossover, or does the subs amp handle this? 3. For the budget price of no more than $300 what other combination of subs, and amps could I look into? 4. Will the subs listed be able to handle 450watts RMS if I choose the bigger 900 watt RMS amp? 5. Will the subs be noticeably louder with the KAC-9105 at the same volume vs the KAC-8105, or is it just better efficiency at that point? 6. Is the calculation 500 watts / 12 volts = 41 amps correct, will 500 watts RMS pull 41 amps, and will 900 watts RMS pull 75 amps from the alternator? 7. What else should I know, anything, as I want to be as educated on the subject as possible, so I don't have to worry about something going wrong once I do purchase the system. [/QUOTE]
