Question about JBL BP150.1 Car Audio Amplifier
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
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 [email protected] 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
