[QUOTE="JSMCO, post: 8673243, member: 670938"] Hi Guys, I have a 2008 Dodge RAM 1500. Kenwood Excelon 793, AudioControl three.2, Old school Boston SPZ60 front doors, Boston Pro 6.0 rear doors, Boston 10.5 Pro 2 ohm sub. (Single Voice Coil) Rockford Punch 801x running the mids, Rockford Punch 500S running the sub. I just discovered after about 10 years that the sub is 2ohm, thus the amp is not bridged, just running the sub off one channel, but it hits hard and clean, always has. The sub is in a small sealed fiberglass enclosure under the rear driver's side seat. It's odd shaped to conform to the vehicle, but I'd guess by measuring it's about .35 cubic ft volume. Tiny but the Boston sub never seemed to mind. The amp says it's 250w RMS per channel at 2 ohms, 500w bridged at 4 ohms. The Boston Sub says it's rated for 50-1100w. So I'd like to get use from both channels on my amp, one is just going to waste. I am not sure what would be the best way to go and I'd really like some suggestions, which could include "just leave it as is" which is fine with me if you guys feel I'd see little improvement for extra time & money. Please forgive my noob questions: 1. I actually have another identical Boston sub. I like the one I have so much, I bought this one as a spare in case the old one ever blew. So option 1 would be have another good enclosure built, run the 2nd sub off the amp's other channel at 250w, and put it under the rear passenger seat. 2. I could buy a dual voice coil 2 ohm sub and wire it to present 4 ohms to the amp or a 4 ohm svc sub so I could bridge the amp and just stick with one sub that would get 500w instead of 250.
