Series/Parallel Config ?

[_S7V7N_]

Okay i got myself into a situation to where i can get two sets of these speakers (4 speakers total ) for a decent price. My amp does 87 rms so if i ran these in series parallel i could run these at 4 ohms i shouldn't have a problem with overpowering them would i ?

These are Audiopipes btw

This is a series/parallel connection (below). Connecting individual woofers in a series configuration is not common in car audio. This is a lot more common in musical instrument (guitar and bass guitar) speaker cabinets.




I wanted to go with all Maxxonics products but....this deal was one i couldn't refuse.

considering your amp is a 2 channel amp... and those speakers are 2ohms each... then a series connection (for 2 speakers) would give you two 4ohm loads.

I think that is what you are asking, not quite sure tho. It is very rare for door speakers to be 2ohms... 99% of aftermarket door speakers are 4ohms.

They are 4 Ohms and i'm running it off the other side of my four channel amp. So i'm going to have four speakers. All are 4 ohms. I have two channels left on my amp. Each channel does 87 watts Rms..So i want to run Two speakers to each channel and i want a 4 Ohm load. That's why i'm wanting to do a series/parallel connection.

you need at least 4 voice coils per amplifier channel to get a series/parallel connection.

If you have 4 coils per channel, and they are all 4ohm coils... then yeah... you can have a series/parallel connection that'll read 4ohm nominal.

These guys are right you need 4 4ohm colis on a channel to be able to gat a 4 ohm load but you are using 2 channels. All 4 channel amps are stable to 2 ohm stereo on each channel so just run 2 speakers in parallel on each channel and you will be fine. You will also get more power out of the amp that way.

the question is why? 3.5?

[_S7V7N_]

Why not ? They'll fit perfectly in the C-pillars and anywhere else i can think of to put them.

[talnlnky]

I also was wondering why you were going with 3.5's... If you are doing a pillar install with them, then I'd urge you to just buy 1 pair of those 3.5's, and then find yourself a 6.5"/7"/8" midbass with a low mounting depth to install in the factory door location. You'd need either a passive crossover between the 3.5 & the midbass, or you'd need another 2 channels worth from an amplifier to get the job done. The midbass would do a great job of blending the 3.5's in with a sub.

I'm just using these to fill in the sound since i removed my 6x9's from the rear to get some air out from the trunk since my seats don't fold down. I have the 6.5 hifonics components in each door which sound awsome, but i think the 3.5's will fill in the rear just fine. I got two sets of these for 20 bucks, brand new, reg price is around 25 -50 bucks a set.

talnlnky, has anyone here ever done a 3.5" in the pillar or dash or a 3 way component set? We are picking up Hertz-Audison and I can have a free set of speakers for my car. They have a 3 way component set with a 6 1/2 / 3 / and tweet.

[talnlnky]

You know, I could probably make due with their subs & amps... and the decks are fine.... but the speakers... even if I was working with their flagship components.... I dunno... to me the components are the most important piece of equipment.

[Palmer812]

I agree about the speakers. That's why I said if I do the Kenwood system I will get a set for the rears but run the Hertz-Audison's up front.
