3rd Generation audio question

got a quick question... ok i have this
2 12" dual subs
http://www.bestbuy.com/site/olspage....=1177112903683

and this
Sony Xplod 500 wat 4 channel amp ( yes i know its from wall mart dont flame me)

http://i.walmart.com/i/p/00/02/72/42...32_215X215.jpg


ok so i know its not a good setup but hey most of it was free and it still pounds pretty good

The subs are hooked up to a single 2 wire plugin in the back. so they are crossed over and made into a single channel.. the only problem is that when i put a channel from the amp up to the subs it splits the power between both... right now i bridged my amp so its using 250 watts to the 2 wire plug in which then splits down to half that to each speaker.... i can take of the back 2 wire plugin are and it reveals the 4 wires that are hooked up to it. i still have half the amp not being used and i was wandering if i briged one side 250 watts to one speaker.. and the other side 250 watts to the other speaker... will this work? will my system stay a 4 ohm setup? or will it be downgraded to a 8 ohm? will i get more kick outa it or just the same? HELP ME!

Also another question... just thought about it... could i take both bridged sides and splice the ends together so i have all 4 wires running from the amp to the 2 plug in ports on the back of the subs... will that work? if so that will b way easyer and save me some work

I am upgrading later on to better (already got all planed) so please dont flame what i have!

why are you using a 4 channel amp to power subs?

If you want to work with what you have.............this is probably the best way.

Bridge 2 channels together to power one sub, and then bridge the other 2 channels to power the other sub.

well if u acually read what i wrote... its all i have to work with and i got the AMP FOR FREE... so yea im using it until i can afford another lol

and should i take out the 2 wire plug in and use the 2 bridges to the 4 wires from subs? or should i take the 2 bridge sets and tie them together in the end and plug them up to the 2 wire plugin outlet?

i did read but still didnt know why you would use a 4 channel amp.. how ever you want to bridge, make sure the ohms correspond or your amp/subs (either one) will give.

to be honost with you, dual sucks. Flat out. Anything best buy has in their store is nothing you want. You could be kenwood subs that are 3000 watt peak and an 1800 mono amp and I could out-thump you with my CVR's.

Wattage as claimed by manufacturers completely misguides the customer. If I were you I would stick with top of the line brands if you want your stuff to last.

Kicker, Boston Acoustic, and Kenwood Excelon are the brands I will personally vouch for. My friends say MTX also makes some good quality audio equipment.

When you drop 2k on audio/car electronics at an audiostore, you pick up a few things

if you have DVOM then you can test it. but yeah if it work then leave it.. and becareful with the gain, if your under powering your subs and have the gain to high it, start to clip the sound wave and cause distortion and whill fry your subs.

anything can last if you use it properly. and manufacture put the peak watts for sales purpose. when buying an amp, always look for the RMS rating and if it has sub sonic filter. and you definalty dont need to drop 2k on a system to learn.. and i probably can out-thump you with my 500 watts RMS with 2 12s. just getting a 1000 watt RMS amp wont do you any good unless you get the right amout of voltage going to the amp.

It helps when you dont have any electronics being used to run your vehicle with the exception of the ignition

I could use another battery though

DUALS ARE GOOD FOR THE BOX THEY COME IN!!!!!! I used to work at a electronics store where iused to get half off on car audio and the duals came out to 30 bux 2 12's w/ box! too bad they ran out =( and yeah im not gettin any distortion YET! andi think my setup may just be right i set it up to 4 ohms @ 250x2 and i dont think the 10's are more than 200 rms each so yeah i should be fine

3rd Generation

i agree with everyone. yes i know duals suck... but i only bought them for the box... the speakers just came with it :P i love the box and its asspects of being a 4 ohm compition box.. the specs for that box are outstanding.. just the speakers suck. i am upgrading soon to 2 12" kicker comp vr's now i may have to tamper with the box to get more bass outa it but yea. i have big plans for my system im just going with the stuff i got cheap or free for now cause one day iw as bored and just threw it in one day :P but yea.. i under stand what everyone is saying. now i did try running both bridges and it ended up over powerin the amp some how bright red light came on.. good thing it had back up cause all i had to do was turn the car off and back on to reset the amp.. so im still only running one bridged side ATM but im gettin new amps soon and all that good stuff.. just money is my issue right now

long story short, you need a new amp

http://www.walmart.com/catalog/produ...uct_id=4541642

here are its stats...

it can only put out 200wrms @ 4ohms - presumably, this means when two channels are bridged, since it mentions a low-pass filter

as for if you split the amps, you're right, you'll be splitting each sub to an 8ohm load, so that won't help at all either...it'd still be exactly the same as right now 100wrms to each sub
