Hi fellas,
I am wishing to hook up an older model, self amplified 8" Bazooka (EL8A w/built in 50 watt amplifier) behind the back seat of my crewcab Ford. I have a couple of questions, bowing to the knowledgeable gurus here!
It is a completely stock stereo, which I believe is 4 ohm wiring. The manual I've read allows for either low level RCA or high level connection, simply tapping off the rear speakers, I plan to do the latter. The specs for this Bazooka is 2-ohm. Is this a problem? If so, what can I do to correct this mismatch?
Secondly, for power they recommend a direct, fused connection to the battery. I happen to have an inverter under the backseat that has a hot 8 gauge wire to it. Can I just tap into that? I really don't wish to run another wire all the way to one of the batteries again, it's a long way!
Third (and lastly), and since I am so ignorant on all things audio, since the signal to the sub is from the rear speakers, if I cut the bass on the head unit, is that going to negate the bass signal into the sub? How about if I leave the bass up to all four speakers and run bass blockers?
I just want to round out my crappy stock stereo sound inexpensively, but I would like to optimize it as much as I can of course.
I thank you in advance, this is an incredibly valuable forum!
To the best of my knowlledge, most stock stereo's do not run at 4 ohm. Alot of cars i have seen run at 10 ohm, ( no clue why) anyhow. Yea, do believe that if you lower the bass on the speakers, you will also lose the bass from the sub. its just amplifying a certain frequency of the signal it recieves. As for wiring it, i would just run it in series, to be safe, because i could be wrong and you do have a 4 ohm set up. The inverter you have, do you mean like a power inverter for plugging stuff in? If thats the case, I guess you could. I wouldnt see why you shouldnt be able to. if you do, I would still fuse it, just in case. You never know. Good luck man.

Thanks for the reply, Pimp!
Yes, it's just a 400 watt power inverter, very seldom used. It's on a 40 amp fuse at the battery but I would definitely still fuse the sub too.
All I know about the stock system is that the speakers are 4 ohm. I guess it wouldn't matter since the input to the sub is just that, a signal input, it's not driving the sub's power?
I guess I'll try it out without the bass blockers first, maybe I'll just disconnect the rear speakers entirely, since you can't hear them where they're located anyway? It wouldn't be a major loss if the fronts get blown up! lol
Anyone else have an opinion? Thanks!
