Adding Aplified 8" Sub To Monsoon
Adding Aplified 8" Sub To Monsoon Hi I have a 99 T/A and when I bought it both monsoon subs were blown so I bought a brand new set of Infinity 62.7 2-ohms and the suck for bass so then I ordered 2 replacement monsoon subs and blew one but I must admit the monsoon subs sound pretty good when both are working so right now I have one monsoon sub and one infinity 62.7 it sounds okay but it isn't enought bass it doesn't give out the kind of bass expected from a factory premium system so here's what i'm planning on doing adding a bazooka or other small enclosure type amplified 8" sub because all i'm looking for is premium bass not ground shaking but just something that gives me some thump the reason is that I dont want to add a box and subs and amps because it would add alot of weight to my car and I would have to pay alot of money to get it installed when ebay has bazookas and other type aplified subs for $120 and below with everything I would need to do it myself so has anyone ever used this set up if so how does it sound, is it a good setup, and how hard is it to install. Thanks

I'm sure someone on here has done it. I have Pioneer TS-M7PRS midbasses in place of the stock subs. IF I ever felt the need for more bass than they give, I'd probably go with a small powered unit like that. SHould be an easy install. Just need to run power and pick off the audio from one of the sail or hatch speakers.
A 8" or 10" tube will give you what you are looking for. Remove the factory sail subs completely, carefully tape off the connectors, and if possible stuff the cavities with fiberfill.
Grab the high-level inputs for the tube off of the radio outputs (tapped at the input harness of the monsoon amp). If you tap them from the speaker connections you're getting an extra layer of distortion from the monsoon amp, and not all of the speakers get a full-range signal.
You are still going to need to run a fused power wire from the battery, and a new ground in the back. Grab a cheap 4 or 8 gauge wiring kit from eBay, and stick a fuse in it 1 step above the tube's fuse rating as close to the battery as possible. DO NOT SKIP THIS STEP! The factory amp power lines will not power the tube, and the fuse is critical to keep you from having a 14 foot heavy gauge possible short circuit wire in your car. Use the search, there are threads showing the best place to get the wire through the firewall.
The tube should have a "auto-on" feature meaning the speaker signals act as the turn-on. If not you'll also need to run a turn on lead.
In the end, I would still recommend going with a stealth box and modest amp. The weight difference is negligible from a performance standpoint. The box will provide more bass, and not take up hatch / t-top storage space the tube would. It will also be able to grow with you if you end up upgrading the whole car's sound system.
A tube makes sense if you are on a terribly strict budget, and don't mind losing the hatch space. If you fit that description go for it - it is the cheapest way to add real bass to a factory setup by far.

You can add 8" subs to were the original monsoon subs were. Just cut the hole bigger. If I was doing that to my camaro, I'd be interested in those 8w7's that JL audio make. Just looking at them, you would be thinking "man I bet those things can HIT!".
I thought about adding 2 low powered 100-150 RMS watt range 8" DVC subs and putting them in a box instead of using the sail panels and usind the stock monsoon amp but I don't know if the monsoon amp is strong enough and I wanted to use the bazooka and other type amplified sub because I wanted to install it my self and dont want to spend more than $200.

Infinity makes a 200w self-amp'd 10in sub. I think there around $300, but you can find lots of them on ebay for way cheaper. And then they have a square shaped one thats 250w and costs a little bit more. I'm sure one of those would be a better buy than a bazooka.

Hi Thanks for all of your help it is greatly appreciated Iwent ahead and ordered a 8" DVC Rampage Amplified Bass tube and boy does it give out alot of bass it makes the monsoon system sound so much better and I would recommend to anyone that an amplified bass tube is the way to go if your not satified with the bass that the factory monsoon system offers and don't want to add alot of wieght , spend alot of money, or add an overkill sysyem to thier f-body I ordered mine off of ebay and I only paid $55 for it brand new in the box it has 200 peak watts and about 100RMS watts and its well worth the money and ebay has more for about $60 +$15 for wiring and I strongly recommend them they won't give you ground shaking bass but they will give plenty of bass. Thanks
