Old School Rockford Fosgate Amp

Recommended Posts

Hey guys I recently got a old school Rockford Fosgate Punch 360a2 amp and could use some insight on how I should hook up my single 12" Eclipse SW8122DVC 4ohm dvc sub. I currently have the sub wired to 2ohm from my last amp but was wondering how I can get the most out of this old school rockford amp with this sub. Ive also heard these older rockford amps are highly underrated and was also wondering how much this amp actually produces...Anyways should I leave the sub wired to 2ohm and bridge it or? It says bridged is 4ohm but each channels can be 2 or 4ohm so I don't know how I should wire and hook it up. If not bridged, what about wiring each 4ohm coil to separate channels or no cause it has 2 gain controls for each channels  (left side gain & right side gain). Hopefully someone can help me out. Thanks for the time.

2 ohm bridged will be running it below what its capable of.  Might be fine, might blow up, im not familiar with thosr amps.  Safest is to run it at 4 ohms per channel.

Acrually that amp is only rated at 90x2 at 2 ohms.  Get a different amp

4 ohms stereo, 2 ohms stereo or 4 ohms mono are your options.

people need to state how many ohms each coil is instead of "4 ohm dvc". Its a dual 4 ohm coil sub, so you can wire it up to 8 or down to 2, neither of which is ideal for that amp. Get a different amp or a different sub. Or keep the amp and get another one for this sub

2 Rockford p3 12s (dual 2 ohm)

Pioneer AVH-2300NEX

2 PPI PC275's running 1 sub each atm, waiting to put the SQ 2200.1 back in and add the PhoenixGold Elite.4 once my electrical is up to snuff

Front stage:PRV Audio 6MB200 6.5 and Massive Audio CT2 tweeters

Rear speakers: stock

I just added 5 SoundQubed stickers, and despite having no equipment upgrades, it added 76 DB!!!

I wouldn't run it at 2 ohm bridged, especially since it's old. Those amp are not cheap to repair and you'd be better off selling the amp and getting a mono block. Once you blow that amp you lose 70% of its value. 

 

You  can run it at 4 ohms per channel if you just want some complimentary bass and not output. But don't expect it to be loud.
