I have a alpine 10" sub and I was planning on just wiring it into the back speakers. I have a 180w head unit. I am planning on going big w/ an amp and professional install. But for now I would like to use what I have. My ? is if anyone know of any type of high frequency in-line blockers. The same as bass blockers for tweets. I appreciate all help.

 

Your HU does NOT have enough power to run the sub, you will only damage the sub or the HU if you try, and adding a coil, [passive lowpass x over] isn't going to help 94

 

Buy a amp because it will cost more to replace everything then just buying an amp and a wiring kit.

At least use something like this:
http://cgi.ebay.com/ebaymotors...wItem
(its something but i dont recommend)
but take a look you might find a deal:

Also check out pepboys, bestbuy, or any audio shop.

If you live in socal i can hook you up with a alpine system:
12" sub w/ incloser
2 amps
front and rear speakers
cd changer
head unti

Sorry i dont know much about it because i never installed it i just heard that we offer a kit like that. the price is 50 dollars but you have to pay for installtion on each item. so in the end it will equal about 350-450 depending on your car/truck

 

What in the world kind of head unit claims to put out 180 watts?

Every head unit does...when it gets struck by lightning...didn't you know that?

 

180/4 max power i.e 45x4 or (20x4 rms)
pioneers are set up to bridge the rear channels to use for a super efficient cub, but who would actually do that (gobs of distortion)

almost any since 98, I had a deh-p315 in 98 that had that function, its so useless tho, the old manager at my job ran a pioneer sub and pioneer components in his crx it worked for that application but thats cuz of the size of the car and cuz its an open area.

 

I can't find a DEH-P315 or any 315 model for that matter at Pioneers website, even their archived manual site does not have one 94

Because theres no pioneer with that model number. I even called them and asked if it was discounted but nope they never had one.

this also what you get from google:
Your search - DEH-P315 - did not match any documents.

sorry, it has been like 7 years since i had that radio, it is deh-345 not 315.
my deh-p6000 did the same thing, as well as my deh-p720 and my deh-p7300.
I have never checked my current radio.
to get to that function in a pioneer radio you have to hold down source for 3 secs then hold down audio for 3 secs then u get a menu that says rear sp/ full, u press right and it goes to rear sp/sw it low passes the rear speakers and you can bridge it. try it on one.

But enough of this, you need to read the post, I am not saying that Pioneer didn't have switchable rear speaker outputs, they did and for some time now, but we are talking about bridging.........

I went and checked some Pioneers including the DEH-P720 and the DEH-P7300 and although you can switch the rear speaker outputs to "Rear SP:S.W." the instruction is, "If you switch Rear Output setting to the "Rear SP:S.W.", you can connect a rear speaker lead directly to a Subwoofer without using an auxiliary amp". that's "a" rear speaker lead, nothing about bridging or how you would do that, I even checked the install manual, and it only shows one sub per output, no bridged mode.
