I think the blue wire is a standby "on" to be hooked to separate or system switch. Without knowing how you have system wired, I can' offer much. A bit of caution; having a thousand watt amp hooked to 6x9 dooms their fate

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

We installed the amp and bass package and the subs are not nowhere near *** powerful we think its the amp and when the remote bass switch when we turn it it doesnt change


what product brand did you install. do you set the amps x-over and gains a sub sonic filter right
need to see if the amp is on check led light on amp. make sure your subs ohm load is correct for the amp.

let us an example fake amp 500x2channel max output 1000watts

if you wire your subs at 4 ohms you 250x2 rms stereo
if you wire your subs at 2 ohms you 500x2 rms stereo
if you wire your subs at 4 ohm mono you get 1000 watts

if you have the input voltage of 14.4 all the time at the amp

whats the equipment power

What would be the best amp to push 2 kicker 15 L7s


find the ohms on each subwoofer and how much it can handle. If you have two 4 ohm subs get a powerful MONO AMP and hook it up in parallal. If you have two 2 ohm subs get a (1 ohm stable) Powerful MONO AMP and hook it up in parallel or a powerful 2 CHANNEL AMP but the wiring can be a little complicated cause you've got to connect the subs in series and bridge it on the positive of 1 channel and the negative of 2nd channel for maximium benefit without burning out the 2 channel amp. If you got two 500 Watt subs then you got to find an amp that can put out 1000Watts anything less wont sound good and may burn out the subs because of too much distortion cause of lack of power.

Legacy audio LA590 car audio amp protecet mode


Is that on all the time or are you saying the light is on? If that light is always on that just means it's protecting your amp. If it's off and not playing bass then your in trouble

My subs/amp are not working


when you car is running, it charges the battery somewhat. So the voltage problem is not a problem. The red light means the amp is going into ''Protect Mode". This usually happens when something is wrong with the amp. Usually the amp is getting hot. Check all of you connectiong and check the final impedance of the subs. Make sure the amp can handle the impedance of the subs. If you need anymore help, message me.

Amp burned out but fuses still good?


this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

No sound from my front and back speakers in my van ive got subs


Make sure that when you hooked up your 4 channel amp to the remote turn on lead it is the same as the sub. Only hook amps to the Blue w/ white strip. The solid blue is power antenna lead and will lose power when on CD, ipod etc and only stays powered when the Tuner is on. Hope this fixes your problem.
