Sub install?

[87gtVIC]

I want to know how you guys connected your subs.

I have a four channel amp (http://mobile.jensen.com/jensen/Jens...=POWERPLUS1304) and i will be running the rear deck speakers and my sub (sub will be bridged) off of that amp. The manual for the amp says that it can be done so i shall do it. I am just unclear about a few things:

1. My headunit has a left and right sub out so i guess i would run that to the amp.

2. My amp has a selector that enables me to run 2 channels, 3 channels or 4 channels. If i have my rear deck speakers on channels 1 and 2 and my subwoofer bridged through channel 3 and 4 what mode do i run the amp in? either 3 or 4. That i am really unsure of.

i just use the RCA audio outputs on my deck to run to the amp, just a heads up jensen is known for blowing out one channel when in bridged mode also you might like this amp better

not to mention it is cheaper too. it supports multichannle as well as 3 channel mode too che ck it out i swear by hifonics mang they make some awsome stuff,plus it wont over heat on you.

You will run the amp in 3channel mode, this should bridge only the rear channels.
Looks like as long as your sub is a 4 ohm load you're ok.

i have three sets of rca's coming off my head unit, the front and rear go to a 4 channel amp, the front channels go to the dash and the door speakers, the rear channels go to the rear speakers, the sub output goes to a two channel amp and to a pr of 12" subwoofers.....off the front channels of the head unit i have a pr of satellite tweeters on the b pillars

That is still expensive!

And i would still run the left and right Subwoofer RCA's from the headunit to the amps input on 3 and 4?

Jeez Scott. You just used the world supply of speakers in your car.

not really in comparison for power,quality,and performance the amp above is expensive lol at anyrate you should see the amp im getting it is a monoblock and will run me almost 300 for it it also pushes 1500w @1 ohm RMS!!
rms is what i look for i cant decide if i want to buy an L7 kicker or a hifonics colossus sub both are 15 inch subs im only buying 1 for now lol the amp is also hifonics, btw a monoblock is best for running subs. there is a place in nycity that you might want to check out lemme see here....Mailing Address:

yes indeedey! Dont forget to take the rear channels off 'sub mode' - the 'sub out' RCA's should already have a low-pass filter.
You'll want to use the rear RCA outs for the 6x9's if you want to retain some fade ability, but that will fade out one pair of your fronts if you have them hooked up to the rear speaker outs, but it wont be very significant as long as you just adjust the fade a little.

Stop tempting me. I am cheap bastard trying to get this done for free.

Ok awesome. Really good to know. Still considering purchasing another amp to run the sub though. I will see how spendy i feel after my summer work is over.
