question about dual subs and 4-channel amp

[prophetik]

i've been browsing classifieds for an amp and sub for my 2003 jeep liberty. found a set of 2 10" Powerbass subs in a box with a 4 channel 600 watt Jensen amp. don't have a model on the amp, although i think it's this.

here's my question - can i use this to power either both subs and my four interior speakers (Alpine SPS-600s, two pairs), or one sub and the four speakers? i don't know enough about subs to know if it's worth it.

the reason i'm asking is because he's selling the whole thing for 100$ //content.invisioncic.com/y282845/emoticons/santa.gif.e1ec9cf2e0a0dd232ad35aa594a126d0.gif so if even the amp one of the subs is something i can use, it'd almost be worth it just for that.

edit: alternately, found a guy selling two 12" JL Audio subs and a JL Audio e6450 6-channel amp for 200$. the amp's not a 4/2 amp, but a straight 6-channel, 45w/4ohm or 75w/2ohm RMS per channel. can i bridge the last two inputs for a single basic 10" - like, say, a kicker 10C104 - and sell the two 12" subs? would that be worth it?

Um...if those are you're only choices. I'd probably go with the JL. Assuming the subs are W0s, I would use 2 channels to power your fronts, power your rears off the deck, and bridge channels 3/4 and 5/6 to your subs. This is assuming the subs can be wired probably to a 4ohm load per bridged channel.

But for me, my ultra budget build would work something like a single Infinity Ref 1260/62, Fi X,or CompVRin a ported box.

Use a Rubicon 1.400, Infinity 611A or Alpine MRP-M500. Pick up a Cadence AMP wiring kit and build your box.

Sub - $60-140

Amp-150-170

Wiring Kit -$40

Box - $35

Could have your own better setup (IMO) for $285-$350

what i think i'm going to do is power my fronts and rears off of channels 1-4, and then get a low-power 10" sub like what kicker makes and run that off of channels 5/6 bridged (roughly 180w RMS @ 2ohms, since they're 45w@4ohm now). i'll just sell or barter the 12" box off, as well as the spare kicker sub that comes with the buy-one/get-one deal that's up right now. i don't want huge volume, just some presence, so that'll be fine i think. i'd just need to buy a wiring kit.

That amp wont run at 2-0hms bridged. You could run 150 rms at 4-0hms bridged only.

Agreed. Specs say 150w@ 4ohm. Still, should run a single Kicker Comp.

you're right - i typed it wrong. it'll do 150w @ 4ohms, according to the manual.
