Question about JBL BP150.1 Car Audio Amplifier

I need help, amp OVER heating too much (i think)... Please help

Ok, i have a "boss REV-650 4 channel amp" and have 2 audio pipe (dual voice coil). so what i did was to "bridge" the subs thinking i will get more power. so i connected; The first sub: + (on sub) to + on first channel, then - (on sub) to - on second channel of the amp (thats supposed to be briged). So i did the same thing on the other one (but in channel 3 and 4). And yesterday i was driving with the radio at 25 of 34 (a little loud) so i noticed that suddenly the bass turned off, so i turned off the radio scared then like 2 minutes later i turned the radio on again and the bass kicked in again it was like that for like 3 minutes then suteddown again. When i got home and opened the trunk (the trunk actually was hot) so i touched the amp and almost fryed my hand there. So my question is: is the amp damaged?, am i wiring wrong?, what should i do?. If it helps... i dont have an equalizer (preamp) is directly to radio, my radio is a sony xplod cdx-gt100, the power wire is 4 gauge (same as the ground), i dont have a capacitor and the amp says it should be briged that way what id dont know if is because the subs are dual voice coil is different also the amp is 2ohm stable. Thanks in advance

    also i forgot to mention.... im not cheap but my radio has 2 rca's out so y "cutted" the rca's and added 2 more to make it 4 "exits" to have 4 channels. dont know if that affects in anyway in my problem.

I think your load is too low... each sub when wired in parallel can potentially be 2 ohm or 1 ohm depending on if each voice coil is 2 ohm to begin with,,,,this will cause a clipping situation as described and the over heating problem as described,,,,my email is if you have a digital camera send me some pics including speaker model numbers...I await your information so I can help you... good luck

I have 4 wires what do they do I no to of thim will go to my Kicier ame I Ddont no were the other to go

OK, I am assuming that you have 4 wires coming from the subwoofer itself. Your subwoofer has dual voice coils, this means there are two positives and two negatives. Look closely at the posts on the subwoofer and you can tell. These wires will go to your amp, all four of them. Here's the tricky part. You need to know if your amp is a monoblock (single channel) or two channel amp. Also, what ohms is it stable at (4, 2, or 1). If you have a monoblock stable at one ohm, take both positives from the sub and put to the positive of speaker output on the amp. Then put both negatives from the sub to the negative speaker output of the amp. If your sub is dual 4 ohm voice coils, this will give you a 2 ohm load. If you have a dual 2 ohm voice coil sub, this will give you a 1 ohm load. If you amp is 2 channel, just hook one set of positive and negative to one channel and the other set to the other channel. Hope this helps

I have 1 audio bahn eternal series awes15p 15inch subwoofer.I'm having problems hooking it in my vehicle,I don't have the wiring manual.I would appreciate if you can tell me or give me a...

There are some things to think about when you install this.

1. Is the sub a dual or single voice coil?
2. What ohms are the voice coils?
3. Is your amp 2 channel or mono?
4. What are the ohms loads allowed by your amp?

I am going to assume your sub is dual 4 ohm and you want to get as much power out of your amp as you can. I am also assuming the amp is a mono channel amp. (if it's a two channel amp, you can bridge the channels)

Go from the positive of your amp and wire to both positives of the voice coils. Then go from the negative of the amp to the negative of both voice coils. You will have 2 sets of wires to your sub. This is called a parallel set up. This drops the load of one dual 4ohm sub to a 2 ohm load. The lower the resisitance, the more power is able to flow from your amp, giving your more sound. Make sure your amp is 2 ohm stable.

Hope this helps

Can i power 2 12 subs a rockford punch z and a xplode with this amp i found all this **** in my garage and i need to know if it will power all this

First of all. Using two different kinds of sub woofers, is not an option, as these two sub woofers have different specifications and you should never mix sub woofers. Now the better choice from the 2, would probably be the Rockford. (cant be sure without knowing the models, power handling is also a factor in how well either of the sub woofers will play, but Rockford as a rule makes better sub woofers than Sony does) In my opinion, both the sub woofers deserve a better amplifier than what Boss has to offer. However to connect either of these sub woofers, you would need to determine how many voice coils it has and how many OHM the voice coil/s are. If it is a DVC (dual voice coil) and each voice coil is 4 OHM or 2 OHM, then you can connect one voice coil to one channel of the amplifier and the other voice coil to the other channel of the amplifier. If it is a DVC 2OHM you can also connect it wired in Series/Series to give a 4OHM load and should be connected to the BRIDGE dedicated speaker outputs of your amplifier. If it is a SVC (single voice coil) and it is 4 OHM, then you can connect the sub woofer to the designated speaker outputs of your amplifier that states BRIDGE. DO NOT run the amplifier in BRIDGE mode at 2 OHM as this will probably damage the amplifier. dreamsystems

I need help hooking my kicker cvr 12 to my direct 600 amp

Is the sub a single voice coil or dual???? If its a single, just bridge sub to amp....(+ of one channel and the - of the other) amp should show where to bridge with a diagram near speaker outs. If its a dual voice coil, then run one voice coil to the left channel and one voice coil to the right.

I want a reliable system.

if you bought that equipment today then your answer is yes your amp will power the subs but if i was you and you want more bass I would go with a two channel amp or even a mono block amp that will be 1 ohm stable and if you decide to do that you might want to get subs that are dual 4 ohm voice coils and run them in series that will get you 1 ohm of resistance

Volfenhag ZX4725 i am buying this subwoofer and

No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw. WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula) see below.

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you.
Everything is a function of Resistance and Ohms law.
Current (I) = Voltage (E) divided by Resistance(R).
Voltage = Current Multiplied by Resistance.
Resistance = Voltage divides by Current.

Whats the best way to hook up a 12 inch dual voice coil insignia subwoofer spkr to a 4 channel 650 rev boss amp

Well without seeing a spec sheet on the amp and not knowing your voice coil impedance I will assume the following. If the speaker is dual 4 ohm voice coil the in parallel it would present a 2 ohm impedance to the amp. If this amp is stable down to 2 ohms bridged then that would be the hookup of choice. If it is not stable to two ohms with one speaker it will be tough to get full performance out of your amp. You would have to series the voice coils which would then present an 8 ohm impedance to the amp. Just look at your amp's manual before making the decision. My suggestion would be to get another one of those subwoofers parallel the voice coils on each then wire the two subwoofers in series. This would give you a 4 ohm load which your amp is almost certain to be able to drive.

scanman84: i would recommend using the 2 channel 300W amp to drive the dual voice coil alone. i wouldn't combine the single channel amp with the 2 channel. you can't tie the 2 channel outputs together & use that on 1 voice & attach the single channel amp to the other, plus there could be slight differences in amplification & timing which, could cause the sub to have minimal movement or cause a canceling effect which would reduce the spl, sound pressure level. if you need more volume use the lowest impedence speaker recommended by the amp's mfg & if you need serious volume, go with a higher output single 2 channel amp. just make sure you have sufficient wire size to handle high powered amps. example, 8awg wire is rated for 73 amps. also make sure the amp is well grounded with nut & bolt connections to the frame & that there is good ventilation.
