strapping bre2500s

[BlurredVision 10+ year member]

I have a couple of q's on this amp. I'm really thinking about buying a couple of these and strapping had me confused. I've looked at the manual online and I see how it has two strapped with the jumper wire going from one negative to the other, but that is with one sub between the two amps. If I wanted to use two subs, do u run another jumper wire from positive to positive to balance it out? I've also heard these amps are fairly strong. I know it is bridged at 2 ohms, but could I bridge it at 1 ohms with no problems? Or would it have to be a half ohm? I've heard they can handle a half ohm alone

LOL @ whole post. If you ran a jumper between both positive and negative you would short both amps. WTF are you thinking? Also, if they run at 2 ohms strapped, don't go below that for music. You will again blow both amps. The amp doesn't know the difference between 1 speaker and 2 speakers so you would wire it normally.

I guess that was helpful, but that groan was messed up. I've know I've heard on amps being strapped at lower than 2

For burps.... not for music. Huge difference. The groan was deserved. Your owner's manual covered it.

bro... he was just asking a few questions.. dont groan him and yell at him for what he read... Real professional.

OP. to strap the amps, you have RCAs from your HU going into one. then run one linking rca from one amp to the other.

The amp with the rcas from the HU you make it the master amp

and the amp without any rcas from the HU, only from the master amp, "slave"

each amp gets its own power, ground, remote.

however you connect the +'s from the slave to the -'s of the master.

connect the subs to the masters +'s and the -'s to the ground points of your vehicle.

That's not true. If it's a korean board at least, both amps negatives connect together. The slave amp's positives are actually ground. The master's positive are positive. Groaning isn't messed up. It's a feature to use when you feel like it. Mine was warranted as he said he read the manual and still wanted to do two different things that will surely blow the amps. I groaned you as well because I didn't yell. I typed. You also told him to wire for fire.

I see what he meant be playing it safe, but it sounded like the amps were solid enough to try it

I'm by no means saying the amps are junk. I'm saying that when the amps are supposed to be 2 ohms strapped, wiring them at 1 ohm strapped is like running each at .5. That sounds ok to most until you factor in that you have twice the current draw than just 1. So you are compounding your problems and will run into problems. Going even lower to .5 strapped is just not smart.

wait, show me instructions that show an amp that straps like that......... all the amps i've strapped, and seen strapped, you always connect one side of each amp, - on all the ones i've seen together to connect that section of the board together, making it one big amp board. then, one is setup with an opposite phase, so while the + of one amp handles the first half of the wave pushing the sub foreward, the + of the other amp handles the opposite side of the wave, pulling the sub back, essentially, one amp is +, and the other amp is - and the jumper passes the resto of the circuit between the 2 amps. in the end, you are left with a single mono channel, only hook the sub between the 2 positives. in this case, it is a 2ohm stable amp, period. whatever you do, wire the subs to at least 2 ohms. should be able to handle 2-8ohms, and the power will be 2x what one amp is at half the impeedance. also, you never ever want to hook a speaker lead to any amp, or head to ground, on anything with it's own power supply. that was eliminated in the late 70's, to the 80's.
