Dual Amp Installation- How to keep bass going to the sub and not the speakers

[BoxLife]

Hey all! Here's what I've got.

7" JVC in dash. Front Preouts, Rear Pre-Outs, and One Subwoofer Pre-Out. (Meaning its one rca female not two)

15" CVR and (2) 10" CVX

Hifonics 1500 Mono Block

JL Components Front

JL 5 1/2 Rears

Clarion 5 Channel

Right now I have the subs all running on the Hifonics at 1.3 Ohms... sounds great been working for months.

I have the Hifonics amp running to the rear out on the radio. The problem I'm having is my last set of components and my old 5 1/2's blew due to too much bass. But if I turn the bass down, I lose sub sound.

What I want is to wire my speakers to work like they should (on the Clarion), and reliably not blow, and have big boom from the subwoofers.

So how would I go about wiring this?

Thanks in advance.

You have an amp for your highs so just set the crossovers on the amp to cut everything below 100-120hz out.

OK and in regards to RCA hookup. I have a pair for front channels and a pair for rears. Do I then run rca from clarion to hifonics?

You could or you could run a single rca from the sub out and use a y-splitter at the amp to connect to both inputs on the amp. If you want to use your subwoofer control on the hu, you need to do it this way. You have a single rca out for the sub out because it is a mono output. You are using a mono amplifier so it really just coincides with one another. Doing this would also allow you to cut the bass out at the head unit without losing the bass to the sub.

That's what I want to do. I had just heard using a splitter wasn't good.

just use a 2 channel set up using a spliter is only going to cut your imput voltage down.

on the stereo settings set the sw to mono.

Im gunna jump in here and say one more thing as well... Get rid of one set of your subs! Either pic the 15 or the the 10's.....

Why delete one or the other when it comes to subs? They sound good as they are right now, so I'm just curious as to the reasoning behind that.

I heard a system at a show recently, the way it was setup the smaller subs (8's or 10's, I don't recall, hit on the higher frequency bass notes, and his 2 15's hit on the really low frequency notes. And all the mids and highs sounded great.

Also, kramer_212, are you saying switch to a 2 channel amplifier? I'd prefer not to do so. I'd like to use the amps I have if at all possible.
