I am trying to hook up some subs but they wont go. they are rfp2215's and the amp is t3-500. this should work. the amp is turning on but the subs arent going so I thought it might be my wireing. I wired them 4 times. each differently. first time I wired them to 4 ohm, second to 1 ohm, third time single 4 ohm and forth time I had them at 1 ohm each. not once did the subs turn on. I heard them go before I bought them so im sure there not blown . Im out of ideas of why there not going.

I hook up my other system and everything works fine.

my second problem is that everytime I un-hook the rca's from the amp. it turns off.

I need help getting this going.

how are you grounding this amp? and are you running sufficent power to the amp? what is your headunit, and does it have a filter on? perhaps try making sure your filters are off and then post up some more info on your system/

head unit is am alpine cda 7897, I am grounding it with a wire to the frame in the trunk, same as I had for the other system. im new to the digital amps so I dont know what one says volts. the display on the left says 9 and the display on the right says around 11 if I remember correctly. for power, the power is running right off of the battery. I dont know what else to say..

im stumped to as of why when I disconnect the rca's from the amp..it turns off. when I do that to my previous amp, it stays on but the subs dont do anything.

That is why instantly I thought ground..The rca's are grounded (outter shielding), and if you had a system previously in and grounded to the same spot. it should be fine!!! Try moving your ground to a diff. spot of the vehicle, and if you are running @ 9 and 11, Left is voltage if I am not mistaken and right is tempurature(spell check). You might want to look into that more

hmm..the rca's have a seperate ground, should I use that? I never did on any other systems so I didnt figure I needed it and dont know if I do still.

the number on the right display moves like up and down but the one on the left stays at 9. something I forget.

yea I just grounded it in a diff place, hooked up old system to see if it worked, it did so I hooked up new system and got the same thing. I dont know if its an amp problem which would suck because yet it is new, its second hand so no warrenty but the amp was good when I bought it. he hooked it up to the 1 sub he had to show me it goes, get home and get nothing =(

Sounds to me like the amp is scarooood... if it turning on and off with the rca cables being plugged in or not, then you have a bad ground or a bad amp.

i have a t3-500 and yes the left is Volt, right is temp.... so your amp is reading 9 Volts which is not good..... what gauge wire are you running? have you sanded all the paint off your grounding point?

you should have minimum of 4 gauge power and ground for that amp....

9v lol check to see if your car starts

punk2001

9V with the car on aux. you gave me ideas of why it might be happening. I didnt know the size of the ground mattered sso im going to get 4 guage for that and get 4 guage for power too. right now I had 14 guage ground and 8 guage power so like you said..it could be why its ****ing up. If not..im just going to get someone to re-wire my whole set-up from the deck. (im too lazy to do it again)
