i just blew my solobaric???

i have a kicker solobaric 12" L7 and just installed a RF bd1000 amp (i was running it with a RF 200.1 amp and it wasnt enough) ok well i turned it up and it sounded like a completely different sub, my whole car shook... worked great for about 30 mins to an hour then after leaving my friends house where i installed it i lost all bass. i pulled off the freeway and checked the wiring and stuff but nuttin... got back in and restarted everytin and it worked for like 20-30 seconds then quit again.

when i got it home i opened up the sub box (sealed) and there was smoke up in there like an electrical burn... and it hasnt worked since... i know the subs have a max rms of 750 but ive known a lot of people runnin 1200.1 amps in a sub like this... where did i go wrong... it was like the sub overheated....

HELP!!!

oh yea... if i dont wanna blow another sub but want more bass do i have to buy 2 subs to make it louder but share the power???

lol this thread can go on for a long time.... but yea you blew it. when u turn up the "gain" on the amps it doesnt provide a constant wattage to the sub. so basically what happened was the amp pushed say 600W of power for awhile durring a musical sequence, but the gain is set to a level beyond that. so when a musical peak happened... the wattage goes to 900W inorder to play that sequence. the RMS on the sub is 750 so beyond that is Peak power territory. Thats why prolonged power beyond 750 will overheat the voicecoil, and lastly, melt and seize the sub, hence blown sub. and thats what you saw from the smoke and stench.

in the future, i'd suggest you tune ur amps both by listening and visually. you can clearly tell when a sub is being overpowered. adjust it at a volume you listen to normally. then keep that in mind. beacuse certain songs have stronger bass thanothers. so sometimes u have to adjust the bass on ur headunit to compensate. Lastly, the crossovers on the amps can have a big effect on the efficiency of the amp and the clearity of the sub. usually cut off points are around 80hz. anything above it would seem BOOMY, anyting below it, will be cutting off some bass tones. so play around with it.

Tuning a system is an art. and needs to be tailored to each indvidual listeners taste. It's an endless ongoing process.

Have fun. Just be easy on the "gain"

How to set gain, lesson 1:

First, gain DOES NOT EQUAL a volume control. Gain is a feature implemented to acheive maximum sound quality and minimum distortion at a given volume level. What is the loudest comfortable volume where you would listen to your music? Ok, find that and put on some bass. Now, go to your amp and turn the gain all the way down. Adjust the gain slowly upwards until you hear the sub(s) start to distort. Distortion in subs can mainly be heard through shaking and vibration and generally not sounding right. If you cannot identify distortion (like if you can't tell how factory systems distort at higher volume) stop reading this and go to a stereo shop. I'm sure they'd be happy to help you. Anyway, basically the way one adjusts gain is to minimize distortion at a desired volume level. For example, my system is set to sound its best at volume level 40 (40 means nothing, just an example). If I were to enter a SQL comp., I would play at volume level 40. I hope this helps.

the solobaric can take a lot of power... instead of getting another one just get the one 15" solo... play around with the gain, have a song with a lot of bass and a friend controlling the gain while you sit in the drivers seat so you can tell when it sounds good... too high and it sounds woolly... Good bass it fast, punchy bass, not bass that makes your ears bleed... Well, not always... =)

ps. are u running caps and an uprated battery in your car? you should be with that much current draw from ur battery.
