Hey car audio folks..

[helhedded]

I'm working on replacing the stock 8" subwoofer in my HHR. The car currently has a 7-speaker Pioneer system that is powered by one little 250watt amp. My plan is to leave the stock amp and door speakers in for now. The stock amp will continue to push the other 6 speakers.

The sub I'm looking at:
TS-SW841D - 8" Shallow-Mount Subwoofer with 500 Watts Max. Power | Pioneer Electronics USA

The amp I'm looking at:
MTX TH350.1D TH Series mono sub amplifier — 350 watts RMS X 1 at 1 ohm at Crutchfield.com


I'm going with the shallow 8" because it fits in the stock sub box and has decent specs. I picked the amp because the RMS matches the 125w "nominal" rating that the sub has and it comes with a fancy remote.


Any thoughts on my selections?

If it was 20 years ago I'd be laughing at your Pioneer and MTX crap.

Too bad you can't fit a DD, Fi, or a SMD in there.

There were some like new mid 90's RF Powers in the Minneapolis craigslist about a month ago and I'm kicking myself for not buying them.

:ror:

I used to get crazy with it too. 2 JL 12's, then 3 Memphis 10's.. all in a tiny hatchback. Fun stuff...until when it gets ripped off.

I had a Kicker Comp 15 w/ 1000watts pushing it, and 2 Kicker comp 10's with 250 watts each in a extended cab S10 Xtreme. It was a little loud. But car seats took place of subs. Now Im down to 2 Blaupunkt 12's and a 850 watt Boss in the back of my Blazer. Im not that anoying kid at a stop light. 33 yrs old and I like a bass to my music when I feel like turning it up. Nothing wrong with that IMO.

I wish I could play music at stop lights. Two yellow tops and I'm dipping into 11 volts if my rpms arnt above 1k

You got a belt on your alternator?

Time to upgrade the alternator(s).:twisted:

For hellhedded:
I helped a friend out with a shallow sub in a small box, had a 10 inch kicker with a 250 watt Apline amp.

What made a great difference was to place sub facing the floor. He has a four door Chevy HD. Placed it under the back seat. With about a 3" gap from floor, don't quote me on that, you can test different space sizes.

160a but I keeps it clean :mrgreen:

 

[EeePee]

Actually, I made a mistake. You said you gotta keep it above 1k RPMs to keep it alive, so obviously you have a belt on your alternator.

So the next question is, do you have an alternator?

I agree with the RF suggestion. I've never been a fan of Pioneer subs.

For the amp, I would go with this one
Amazon.com: JX500/1 - JL Audio Monoblock 500W JX Series Full Range Amplifier: Car Electronics

Shooo, you be talkin bout tha bumpity bumps fo real...

160 amp with 1/0 wire including a extra ground going from the alt to the batt. Trying to keep it in a street class but at this point I doubt I'll be able to keep it there.

And to the op. Any company makes a solid mono amp these days. No need to spend JL money.

Not as brand loyal as i used to be. I have beat my mtx mono block, love it. Would go punch sub. First punch amp and punch subs were bought in 1986! Can you say firebird, mullet or jeans jacket? I know I am old. Second system was all mtx and every one for long time after. To be truthfull, low end crap today works and sounds beter than highest end stuff from five years ago. Time alignment alone used to be hundreds now it comes in radios that ade like $100 . You will be fine with what you picked.

 

[helhedded]

Thanks for the suggestions!

 

[WHITE-TRASH]

The only real issues I see with your selections are they are miss matched. Grab an amp that's rated to push good wattage at whatever ohm rating your sub is. An amp that pissed decent wattage at 1 ohm won't do nearly as well pushing 4 ohms.

 

[Hoyta]

That jl amp is moderately priced for what it is. The pioneer shallow subs aren't bad- the only thing is with shallow subs are that they won't give you that "oomph" that a full basket/come sub would. They basically fill the freq range better than components will.

 

[alabamaman]

This is to go into the factory sub spot ? if you have a momo block amp get a dvc 2ohm per coil if they even make those in shallow. OR get a normal full basket dvc sub with mono block , replace the other speakers with comp. sets and a four chn amp . Lose a lot of cargo room .
