    i checked my fuses and my battery connection, the only thing i could find tonight was a wire severly bent that is connected from the amp to the subs. but the wire was still somewhat connected. worth replacing?

    make sure you are getting 12V or battery voltage(I said 12V to simplify everything, a fully charged battery is actually 12.6 and 12volts is actually 10% charged. when the car is running you get around 13.5 to over 14 volts.) the best way to isolate problem, and to simplify eveything. Disconnect your amp. Test it away from the others, If you connected it yourself, that means you pretty much know how to connect them. This is how you test an amp.

    Have a battery ready, and make sure you take your time on this, and have a neat area to test it, don,t do it under your hood, Do it on a table so you can work comfortable.

    Have all your wiring ready to test it. A speaker wich dont really have to be a big one, but you wanna turn the gain down on the amp so you wont burn up the speaker.

    You would really need a digital multimeter, You can buy a cheap one for ten bucks or so, and they are very usefull, you cannot test the amp without that.

    If your sure the connections are good to the amp here is how to test it.

    Remove the amp from the car( it is not a good idea to test it there because all the wiring will confuse you because you have other amps hooked up.

    You will need a pair of RCA cables( the low input cables like the one you use for the amp) If you dont have one( you can buy a pair at a 99 cents store for a buck. Then you need a sound source with an rca output connection.(a cd player, a stereo etc.) You can use an mp3 or ipod, but you need adaptors. Then you need speakers if they are small speakers, ( turn down the gain if you are using small speakers, don't worry it wont burn it out) Last a 12V battery (car battery) and the wires to hook it up( speaker wires and power cables.

    Hook up the spkeakers, power cables etc and the sound source via RCA cables. Doulbe check all connection before powering up( hooking up the remote wire)

    If everything is connected good and no sound, and the light indicates it is on then it is broken. If it is one but there is a protection light that is lit all the time then there is a shorted transistor inside. replacing it would solve the problem. If it is lit but no sound, then either the internal DC_DC circuit or the power to the low signal circuit is malfunctioning. I maybe able to help you fix it if you sent me a photo of the inside at ronald_ross@yahoo.com. I will edit the pic in "paint" and label each circuit section. Then show you what to do. If you are patient, you can do it yourself, and learn how to fix a car amp!! aint that great? Hola bck

My speaker stop workin and the amp is fine and everything is hooked up right


Looks like the speaker is blown , or the wiring inside the speaker is broken. To test if the speaker is working, simply hook up the terminals to the ends of a AA, AAA or C battery. Speaker should make a noise, and the cone should push outwards ( or pull inwards, if the polarity of the battery is reversed). Also test the wires that are hooked to the amplifier with a speaker that you know is good working order, just to make sure that there is nothing wrong on the wiring, on that particular channel in the amp.

Amp is on, but sub wont produce any bass


Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.

I want to hook up my 2 quad coil woofers to a 1ohm amp but


I would look up "series" and "parallel" wiring on the net. Parallel will lower your ohms, which is good- especially for you since your amp is 1ohm. use 1 channel of your amp (unbridged...bridging an amp could increase output, but will Raise the ohms) connect the positive terminal with a wire that goes to the positive on your first sub, and from there, connect a wire from that same positive terminal to the positive terminal on your second sub. do the same thing with the neg. wire. This is called parallel wiring.

Hey thanks alot for the help, the way its hooked up now the amp eventually gets way to hot and the shut-off saftey heat switch just comes on. wondering if you had any suggestions for a good amp along with...


I would definately say, in the world of amplifiers you usually get what you pay for. I would recommend getting a Memphis or MTX amplifier. Go to ebay, specifically search for memphis then in the search options make sure to put in mono or 1 channel. All memphis mono block amps are 2 ohms stable. In particularly I would recommend for you the PR series. it is the Power reference series and they are really boomy for the money. Anything that has the "ST" is getting a little old so I wouldn't recommend it but It still is a good amp, just not sure how long it would last and how badly it's been beaten in the past. Good luck. If you find an amp and are unsure let me know which one and I can help verify it for you.

ELA 500.I


While I don't have any first-hand experience with either Bazooka amps or Memphis subs, this review pretty much says what I initial thoughts were. The amp will do the job without much fuss, so it mainly depends on whether you can get it for a good price.
BUT........
There could be a issue with your sub. According to Memphis, your sub (assuming it's the single voice coil version) is only good for about 250W RMS (let's ignore peak power for now). The ELA500.1, on the other hand, puts out 375W RMS at 4 ohms. You could very easily overpower your sub with that amp.
