Bridging 4ch. Amp

[DaveT 10+ year member]

I just bought an american bass sq480 Link To Specs

and I want to bridge it down to 2chs to power my comps how would I go about doing this? would I hook up 2 sets of rcas one to the front channel and one to the rear? would'nt that be powering one side of the comps off of the rear cahnnel and the other off of the front is that bad? or would I just have to set the gains the same with my DMM? or do you think Iwould be better off just not bridging them and just runn them off the front channels my compnents are MB Quart premium 5 1/4s that are rated up to 100 watts rms so I would just set the gains to 20 volts ac for exactly 100 watts.

Thanks For your help

You would only use the front RCA output from your headunit. You would then get a 2 y-splitters, and split the left side RCA to the inputs of both channel 1 and channel 2, and split the right RCA to the inputs for both channel 3 and channel 4.

or would I just have to set the gains the same with my DMM?

If you are a novice, the DMM method is good for giving you a starting point. From there, you can decide if the gain needs a little tweaking (i.e. if it stresses the speakers too early, you can then turn the gain down some and finish the tuning by ear).

or do you think Iwould be better off just not bridging them and just runn them off the front channels my compnents are MB Quart premium 5 1/4s that are rated up to 100 watts rms

Try it both ways, see which you like better. Bridging will give you a little more power, and hence the potential for a little more output.

i believe that amp has a combine switch to where you only need one pair of RCAs.

that would be nice...save me a lil money on the y splitters....I'll see when I actually get the amp
