    good somone with type r's woop my speciality!

    How have you wired your type r's?

    I will say mixing subs on one amp is not a good idea!





    Output 4 Ohms
    600W x 1



    Output 2 Ohms
    1200W x 1



    Signal-to-Noise Ratio
    >100



    Frequency Response (±3dB)
    20Hz - 500Hz



    Total Harmonic Distortion
    0.1%



    Input Sensitivity
    250mV - 4V

    This is the specification for the amp your are currently using.

    So really this will only support 1 type r depeneding on how you have wired it!

    Could you please tell me how your type'r s are wired so i know what ohms ur running? and wat type r's they are its either 4ohm or 2 ohm :)

    thanks

Check voltage on rca outputs on the radio and on the amp and if those are fine it might be your rca cables them selves

Ouku single din no sound from rca cables


Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

How do I hook up a jbl 12 inch subwoffer to a car head unit


The head unit should have a RCA Sub Out. The RCA wire goes to the Sub Amplifier, along with power, ground, and a blue remote wire from the Head Unit. Next, the Sub Amp is wired to the Subwoofer with speaker wire. Without an amplifier your sub won't make any noticeable sound.

I have a jbl gt series gt5 a3011 amp light on top comes on but the power light doesnt fuses are good everything seems to be connected right and no sound to speakers .


Run a jumper between the power wire and the remote (disconnect the remote wire from the head unit first). If the amp turns on, you got a blown fuse, or other problem with the remote turn on from the head unit.

Your amp could be in protection mode! Sometimes turning up to high or wires touching will put in protection mode! It will have to be unplugged for a day or two to drain all power out of the memory. Leave accessorie/ignition wire hooked up, just not power and ground wiring. It should reset itself.

Hello scottsmad1,

You do not specify the make and model of your amp, so it is not possible to point you to specific troubleshooting information. However, some problems are generic and it appears that you have already isolated the problem to the amp itself.

It's still possible that the head unit does not provide a strong enough input signal, but your amp should have a level control that allows you to match it to the head unit. I'd also doublecheck the other amp settings. If the setting check out, it's likely that the amp is defective.

Hope this helps.

PIONEER DEH-P86DHR NO SOUND!!


With these units, the internal amplifier is an IC that fails sometimes. It can leave the rest of the unit working ok, bit will have no audio. There may be audio from the line level RCA's but not from the speaker outs. Smell the back of the unit to see if it smells burnt. Most of the time it will, but not always. The IC is usually something like a PAL007a or similar. If you are good at soldering, you can order the part, and change it yourself. If not, you will need to seek a technician to replace the part. You may also try an external amplifier and RCA's instead of fixing the IC.
