Please Help!!

i just got a 4 channel 1800 watt crunch p1800.4 amp and i have to 800 watt Pioneer subs now i know not to have the gain up all the way and stuff so i dont blow the subs but im not sure how to wire it if i just wire it normal (conect one to channel one and one to channel 2) or if i need to bridge it witch im not quite sure how to do that really i could really use some help i have about 3 days till i install and i wanna do it right. im not to new to wiring amps and subs just to 4 channel ones.......Please help

Read the manual, it will tell you how to bridge the amp and where to connect the wires. Make sure you do not go below the stable impedance of the amp in bridged mode.

A lot of good information can be found in there.

i know how to bridge it..... and what do u mean?

You could wire them up like you said, each sub to one channel. What are the specs for your amp, the important one being the RMS output x4 and bridged. Being that they are 4ohm subs they could work with you amp in bridged mode. One sub bridged to the front channels and the other one to the rear ones. The only problem might be that your amp might put out too much power for them. Having headroom is good for musical peaks, just be conservative with your gains & volume. Bridging of the amp usually happens when you take the + of one channel and the negative of the other channel. For the correct way to do it on your amp, you will have to look on the amp itself or the manual.

thats the amp stats

and what about a Capacitor? should i get one and if so what size?

unrealii

You wont need a cap. Just make sure you are running a proper size power wire to your amp (or amps if you have more than one).

1996blackmax

Agreed, you won't need a cap.

cadenceclipse

bridged they will see about 500 watts apiece so b careful setting gains. cap won't hurt, battery or alt. upgrade would b better
