Hey ppl. I have a 2 channel Rockford Fosgate 501s amp. The amp specs are:
125 watts RMS x 2 at 4 ohms
250 watts RMS x 2 at 2 ohms
500 watts RMS x 1 at 4 ohms in bridged mode
stereo or bridged mono output
4-ohm stable in bridged mode
I just blew the coils on a Infinity Reference 1230w.
I just bought an Audiobahn AW1206T. The RMS is 1100(so they say). It has dual 4ohm voice coils. My question is: What is the best and loudest way to run this sub to this amplifier? From what the manaul says, the amp is not 1ohm stable. I guess what I'm trying to say is how can I produce a 4 ohm load to this amp with both voice coils being active?
Thanks guys. This amp's manual says not to present a bridged signal that is lower than 4ohms....However I hooked up my friend's Sony's(2 12s) in parallel and presented a 2ohm load and it works fine. If it has been working fine for a couple days is it fine to keep it like that? Somebody told me to just throw in some lower amp fuses to be safe. How true is this?
I have been running a Alpine type R DVC wired at 2 ohms off of a Fosgate 500a2 for 3 years now (in my Jeep). The amp will get very hot and go into thermal shutdown after about 3 songs if there is not a lot off cooling (ie, back seat donw over it). But if the seat is up, the amp will run for several hours before shutting down.
I know it is not recommended, but it works.
I also do the same with my PPI PC2600 and the same sub. It has a fan and has never shut down.
Best option is to exchange the sub or get an amp that is 2 ohm stable.
