what is the best way to bridge my subs

[13sldr]

i have two SPL 15in subs(500wRMS) and a 1200w SPL amp(600wRMS)

i had it proffesionally installed. they bridged for me, they took both positives from the subs and put them in one positive port in the amp, then took both negitive from the subs and put them them in one negitive port in the amp.

i would like to know if there is any better way to bridge my subs.

thats the best wayt to bridge two subs to one channel, if your looking for more power, you can wire your subs in parallel, and this should give you less resistance, therefore giving a little more power. if your amp is not rated for the OHM's that your subs equal when they are wired in parallel, it will most likely overheat and shut down.

anti*commander- his subs are already wired in parallel.
Also this sould be in the audio section, not the new member. Maybe a mod can move it for us.

i forgot to mention that it is two channel and when they wired it up, they have the postives on one side of the amp then the negitives on the other side

if i were to go and get another 1200w 600wRMS, how quickly would it blow my subs if i were to hook one sub up to one amp then hook up the other sub to the other amp

it shouldnt blow your subs quickley, just get all the levels on the amp set correctly and you should be good. if your subs are 500 RMS, then i think a 600 RMS would be ideal, but if its 500 peak, id be careful, and make sure of the ame levels.

distortion is what blows subs usually, not too much power. At least that's what I've always been told. You could put 5x the rated power into the sub and not blow it, but have a lot of distortion and you'll kill it.

i have a switch for the distortion

Welcome to this forum!

a switch for distortion?

 

[13sldr]

yea, i cant think of the names of the setttings, but if it is at one setting then the subs are distorted, but if i move the switch then they arent distored

 

[13sldr]

its call the x-over, and if i have it set to LPF then they are distored, but if they are set to FULL then they arent

I would NOT buy another of the same amp. You would not get the most out of the amps. Not knowing what subs or amps you have I have to guess that you subs are single voice coil that are 8 ohm. So when you parallel the two 8 ohm subs, you get a 4 ohm load to your amp. And your amp bridged to 4 ohms is basically like running 2 ohm stereo. But if you only put one sub on the same amp. You would have 8 ohm bridged or 4 ohm stereo. Your amp puts out 600 watts bridged at 4 ohms so it would probably put out 300-400 bridged at 8 ohms. So like I said to start off with, it is not a goos idea to buy another of the same amp. It would be easier to confirm all of this if we knew what subs and amp you have.

ooooh yeah, forgot about coils, im too used to working with dual/quad voice coils.

if anything you should just keep what you have now, or if you really want to, buy all new subs and amps.

Do NOT listen to this advice. A speaker has no clue if a signal is distorted or not. If that were the case, ANY track on a Linkin Park or Britney Spears album would immediately blow a speaker, but the only time I've popped one was with an orchestral track. The ONLY thing that can blow a speaker is too much power (in a given situation- enclosure is the #1 factor).

I guess I should elaborate instead of just being an #######. A clipped signal (which will definitely sound distorted) can easily blow a speaker, but that's because the amplifier is temporarily putting out 2 or more times its rated power. If you're running a 500 rms amp to a 500 rms speaker, then suddenly the speaker is getting 1000 or more watts, it is easy to see why they go boom.

the owners manual on my subs and amp says that the subs are dual 4 ohms and the amp at 2 ohms 300Wx2CH, 4ohms 250Wx2CH

and the subs and amps are made by SPL

Based on how you described this was wired, its right for what you have. There was another post about not buying that equipt again... I beleive there are different types and qualities out there for sure... but what's most important if that it sounds good for you. Have fun with it!
