[QUOTE="chefws, post: 2920448, member: 576147"] Hey to all you car audiophiles. I have patched together a system that pretty much fits my needs, but isn’t of the greatest caliber. I have limited resources (money), so over the past year and a half I’ve been buying cheap stuff here and there to add to the system. Presently I have a JVC head unit, and RF 300w amp for my 4 6x9’s. I have the following subs: 2) 10” RF 8ohm 200w rms/400w max 2) 10” Sony 4 ohm 500w rms/1000w max 2) 12” Sony 4 ohm 550w rms/1100 w max These are running off of a 1000 w amp with the following specs: 4 channels RMS @ 4 Ohms 4 x 125W MAX @ 4 Ohms 4 x 250W At 4 Ohms Bridged 2 x 500W RMS @ 2 Ohms 4 x 200W Min Speaker Impedance 2 Ohm I presently have the 2) 10” RF 8ohm parallel presenting a 4 ohm load on one channel, the 2) 10” Sony 4ohm presenting a 2ohm load on one channel, and the 2) 12” Sony 4 ohm presenting a 4 ohm load on 2 channels. I bid on a pair of 10” RF DVC 2 Ohm speakers, and didn’t think I would win, but I did. I got 2 Rockford Fosgate Punch Stage 3 P310D2 10" 800W Subwoofer 2 ohms for $40 each. The power handling is 400w rms/800w max. If I use only the 10” RF DVC, I can wire each one to present a 4 ohm load, and bridge it on the amp. That is easy. What I am trying to do is get all the speakers to play off of the amp. (Yes, this is stupid, and I acknowledge that) I won’t be able to use the 2) 200w rms speakers for this configuration. I am thinking that if I run 2 each of the Sony 10” subs parallel to make an 8 ohm load, and configure the 2 DVC parallel to present and 8 ohm load, then connect the 2 configurations in series, I will have a 4 ohm load to present it to 2 channels bridged. I am thinking this will give me a 4 ohm load and an output of 500 watts. Does this sound right? Any help would be appreciated. Thank you. [/QUOTE]
