My kenwood kac 9103d just crapped out on me and i am looking to buy a new amp but when i bought my sub the guy specifically wanted to know what type of amp i had to match it to the sub. so now do i have to get the same type of amp? im confused please help!

im not sure what you mean by what size amp....whether you mean physical size or wattage (power) so I have provided a website link for all the specifications that you require..........

try checking the amps fuses

your amp has a output section problem,contact eric @ Capital Audio & Electronics Repair in Tallahassee,FL 850-339-1130 wee repair all brands and models

My best guess is that it would be your ground wire or even the power into your amp. I would check all the connections going to and from your amp

to get the most power to your subs from that particular amp and those 8 ohm coils just wire the coils in parallel and that will give you a 2.66 ohm load. You will be close to the maximum rated rms output power for the amp that way

Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

My recommendation is to get a line level converter. Go to a car audio shop or even best buy and specifically ask for a line level converter. It will have speaker wires in and RCAs out. Connect the speaker wires to the sub woofer speaker wires and then you will have the RCAs to run to your amp. I hope this helped.

What kind of amp is it?
