I have a kenwood amp with these specs
[align=left] [*] [align=left]Class D Monoblock Amplifier [/align] [*]Maximum Output Power: 1000 watts [/align] [*]RMS Power Output: [ul][*]300 watts x 1 channel @ 4 ohms[*]500 watts x 1 channel @ 2 ohms [/ul][*]2 ohm stable[*]Frequency Response: 5 Hz-200 Hz[*]Low-Pass Filter: 50 Hz-200 Hz, 24 dB/Octave[*]Variable Input Sensitivity: 200 mV - 5 V[*]Line Output Terminals for Extension[*]Infrasonic Filter: 15 Hz, 25 Hz, 18 dB/Octave powering two kenwood subs with these specs

and i would like to bridge it to a power acoustik amp wit these specs
* Full Selectable Crossover Hi/FULL/Low * Three Way Protection Circuit * 2 Ohm Stable Stereo * Tri-Mode Capable * Variable Low Pass: 40Hz-250Hz * Variable High Pass: 40Hz-250Hz

i would like to use the power acoustik to power

2 6x8 4 ohm pioneer premiers, 2 beyma rf one with 110w peak power , or two alpine 6x8 power range: 2-75 watts RMS (230 watts peak power)

when i bridged the power acoustik and the kenwood the subs would beat for a few seconds then stop and one of the two speakers connected to the power acoustik would play significantly louder than the other

whats the problem here?

 

couple of possibilities.... Blown or burned sub - if they are playing at different volumes, from the same audio source(a bridged amp) that would leave me to believe that the subs are either a badley matched pair or that one could be slightly damaged causing it to play different. If you have a ohm meter slap it on the speakers and tell us what you read.


There is always the possibility of bad wiring/connections and that is always were I start. If you have an ohm meter disconnect the speakers from teh amp and and take a reading right there.

 

To me it sounds like your amp isnt powerful enough. I would try wiring the subs in a parallel manner, it will lower the independence of the subs from 4 ohmsto 2 ohms, giving you more juice.

 

Yeah like ttocs said get a meter and check out what the subs read, bc the sub maybe blown or bad. Get the meter and one sub should read around 4 ohms since it is a 4 ohm sub.

 

well i sort of fixed the problem for now

i wired two alpine type s 6x8 and 2 pioneer 6x8s to the power acoustik amp
and left the subs how they were

they worked fine and sounded great until the volume got to 20 or above
when i turned the volume above 20 usually around 22 or 23 the subs would quit but the amp for the subs would stay on and the 6x8s would keep working fine
if i turn it down the subs come back and dont miss a beat subs are brand new and work great without the second amp

 

i just saw the thing about the amp not being powerful enough so i should wire the two subs and one? positive and positive with negative and negative?

 

also i didnt connect the amps through the line in/line out
i used a high low converter to get the RCA's from the rear speaker wires coming from the headset
