Hi, im running a PV1500 for mid/highs (either a pair of PV115's or a pair of older Hisys 2's depending on which band im with) and a Tapco J2500 for subs (2 x Tapco 6918's). We always have to push the PV1500 till the DDT led flickers to get enough volume for the vocals to be heard so i was wondering whether the PV1500 would be safe running in bridge mode for the mid/highs therefore giving 1500 watts @ 4 ohms headroom. 750 to each speaker right? Is the PV1500 safe running at 4 ohms bridge? Also am i right in thinking that the optimum power amp wattage for speakers is around 1.5 times the rated RMS for the the speaker? The 115's are rated 400 watts RMS and the Hisys 2's are rated 350 watts RMS so this setup should be safe right?

Would this setup be safe for the speakers and amp? I run the crossover (behringer CX2310) at a fairly high frequency, 200 hz, to try and keep as much of the low end out of the mid/tops as possible so amp/speakers shouldn't be working too hard.

My thinking is that using bridge mode at 4ohms the extra load this places on the amp should be more than offset by the fact i shouldn't have to drive it so hard to get the vocals to a high enough level and provide enough headroom for the screamo parts of our set.

Thanx for any advice/suggestions

Wayno.
