I have the amp stated in the Title. It's a 4-channel, 600w amp, 2 ohm stable, THD less than 0.04%.
I have two questions.
My first question is about bridging the amp I have. On the bottom, it has a diagram that shows I need to hook the + 4/R to the + on the sub, + 3/L to the - on the sub, + 2/R to the + on the sub, + 1/L to the - on the sub. This leaves the - for all 4 channels on the amp not hooked to anything. Is this correct?
My next question is about using this amp with the speakers I have.
I have 2x Pyle PLW12BL 12" subs, max power 800w each. I don't know the RMS, but someone guessed it at around 150w to 200w. If I use this Legacy amp, bridged, will this be a good choice for these speakers? I know the amp is old and the speakers leave alot to be desired, but I don't spend alot of time in my car and I listen to mainly metal and alternative, with some rap thrown in here and there. GRIN

Update: the RMS of the Pyle PLW12BL's I have are apparently around 350w each.

What will really matter is the enclosure that they are in. Normally the best response are in the larger cabinets, thus power handling will be down quite a bit from the rated rms power. However, for these subs I'm concerned. If the website is correct, specs for these suggest they are more suited for infinite baffle, though xmax (suspension throw length spec) is not given either. If they would to be put into the smallest recommended sealed box (Qtc=1.1), the volume would be very big (8.4cft+).
As for the amp, that does not sound correct. Normally a positive and negative are used per bridge. Example: let's just say you are bridging the rear for simplicity. You should have a right and left with a + and - for each left and right, correct? Then you would take the + from the left to the sub + and then the left- to the sub -, Now you are bridge, simple. Still you need to find out if the right or left + is used and - likewise before utilizing this. I checked the website and couldn't locate a manual on that particular amp. You could email them to know for sure. These amps are also over rated as well as the subs and will not put out nor handle what they claim.
At best, I would imagine if ran like stated above (infinite baffle) you would get bass, but at what volume and quality is yet to be determined.
Hope this helps,

Thanks, that does help. I still have questions, but only the ones that you raised in your reply heh.
As for bass, I'm not that concerned. I won't be entering any competitions or anything and mostly I just want a little extra thump when I listen to metal, which is my norm.
I did think that was kind of strange, positives being used on the amp for bridging, leaving out the negatives. I'll keep looking, though.

I have worked with a few Carver amps (120 volts AC) that bridge in this manner. It's not common to car audio practices and not the norm today either.
Did you locate a copy of the manual on that amps?

Unfortunately, I have not been able to find a manual anywhere for this amp. I bought it used from a friend about 7 years ago and he had lost the manual.

A quick trip to a local shop that carries that brand should be able to help you. Just be sure that the installer is at least knowledgable about that brand and the usual way it is ran. I don't think it will be anything out of the ordinary. If not you could contact the manufacturer as stated before.

Try this link and see if you can get the manual for that model:
