if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

Im looking at this rockford fosgate p700-1bd amp brand new for $300 it comes with a birth sheet it says 750 rms on a 1ohm load. i cant find any reviews about it 225 rms x 1 @ 4-Ohms 450 rms x 1 @ 2-Ohms...


You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

I have a old 2001 rockford fosgate 2 channel p5002 model in great condition just need to know how many watts is it and which subwoofers are compatible to this amp? thanks


Your amp is rated at 500 watts. Here is the break down of your wattage.

125x2 at 4 ohms
250x2 at 2 ohms
500x1 at bridged 4 ohms

When hooking up the amp make sure to use 4 gauge power and ground wire.

Need to know how many ohms this amp is


Safe down to 2 ohms, NOT a 1 ohm stable amp, it will be pushing it hard even at 2ohms but Fosgate's should be able to handle it providing that the install and all cables,wire,connections,etc. are sanitary!
Good Luck !

I have a four channel rockfor fosgate amp and I need to know hows the best way to connect Infinity Reference 1252w Car Subwoofers


Rockford fosgate usually work best with 2 ohm speakers. Depending on the resistance of your speakers, will then give you best connection. Check the resistance for the subwoofers. If the subwoofers are two ohm then connect them directly right and left. But if they are 4 ohm connect them parrallel (positive to postive, negative to negative and bridge the amp.) Good Luck, please rate.

How do you take the dustcap off a p210d2 rockford fosgate subwoofer


You can do this, and I'll tell you how, but I'd like to know why you'd want to do such a thing - you won't get as much bass out of the speaker, due to the voicecoil vent that is present on most subwoofers. This vent would make the box "leaky" and the bass would be seriously impaired.

Looking at the speaker, it doesn't look easy at all.

My usual method is to use a scalpel, and cut (carefully!!) around the dustcap, until it is removed. Sometimes, it's easier to make a starting hole with a scalpel, then use scissors.

Bridging 800a4


That all depends upon whether or not the sub you are running has dual voice coils or just a single voice coil. The 800a4 is a four channel amp; thus the only way you can bridge it will be 3 channel or 2 channel. If you are running a dual voice coil sub then you can wire the amp two channel and get 400 watts x 2 @ 4 ohms. Make sure that you sub can handle this kind of power though.

Here are the specs:
4 x 100 @ 4 ohms (13.8V - <0.05% THD)
4 x 200 @ 2 ohms (13.8V - <0.10% THD)
2 x 400 @ 4 ohms bridged (13.8V - <0.10% THD)
Fuse: External 60A
Manufactured in 1999 - 2001
