amplifier question

use one channels positive and the others negitive but ur amp must be able to handle it or it will overheat id say it will being a fosgate

check the fosgate website, it should say in the specs of the amp if its bridgeable

Need more info about your amp. What is the range of your speaker power...it says 600 watts rms...but usually there's a range and you want the amp to match about midway in the range at least. In your case, 50% of the max is probably close enough, so 300 watts rms from the amp to each speaker.

Is that 300 watts max power to each channel? If so, bridging your amp is like he said above...you wire both speakers in parallel to the positive of one channel and negative of the other...the instructions of your amp should describe it. Make sure the amp is 2 ohm stable. With 2 4ohm subs, you amp will see a 2 ohm load. If you bridge it and its not an amp set up to be bridged, it will probably end up seeing a 1 ohm load since you're halfing the load once by wiring the speakers in parallel and again by bridging the amp. But it will at least double the power output of your amp, but then again its powering 2 speakers.

So anyways, I have a 200 watt mono Fosgate running 2 12's....bridged....and it pounds, so I"m sure you'll be fine. Fosgate amps are really strong. Besides if the salesguy says it will sound good, and it doesn't, tell him you want your money back!

I just checked their site...the amp is 1ohm stable and bridgeable....bridged power to 1 channel to a 2ohm load is 300 watts...probably plenty of power.

Moved to sound shop and to hopefully get you more information.

I'm not sure about new RF stuff, but the older amps were some fo the best. As for the guy that said "it could over heat" thats bull. It will heat normally, amps get hot.. but I dont think you'll have to worry about it over heating. Naturally, dont put it VERY close to your rear seats or anything like that and you'll be just fine.

The guy at the shop is right, and he's saving you a load on an amp but telling you to go this way. If you're budget can handle more, then there are better options out there.

This way will work, and it will save you money.
